Understanding DWI Charges in Lincoln County, Missouri

A charge of Driving While Intoxicated (DWI) in Lincoln County, Missouri can have immediate and long-term consequences. In addition to potential criminal penalties, a DWI arrest may affect your driving privileges, employment opportunities, professional licensing, insurance premiums, and personal reputation. Whether this is your first encounter with the criminal justice system or you have prior experience with Missouri courts, understanding the legal process is one of the most important steps you can take.

Although many people use the terms DUI (Driving Under the Influence) and DWI interchangeably, Missouri law generally uses the term Driving While Intoxicated (DWI). Throughout this guide, both terms are referenced because “DUI” remains a common search term used by individuals looking for legal information after an arrest.

Every DWI case is unique. The facts surrounding the traffic stop, the evidence gathered by law enforcement, chemical testing procedures, witness statements, and constitutional protections all play an important role in determining how a case proceeds. An arrest alone does not determine the outcome of a case, and every person charged with a crime is presumed innocent unless proven guilty beyond a reasonable doubt in a court of law.

Attorney Thomas R. Kissell understands that a DWI arrest often creates uncertainty and stress for both clients and their families. Many individuals have never been arrested before and are unsure what to expect. Questions about driver’s license consequences, possible penalties, court appearances, employment concerns, and the future are common. One of the goals of Kissell Law Group LLC is to help clients understand the legal process while providing experienced representation tailored to the specific facts of each case.

This guide was created to provide practical information for individuals charged with DWI in Lincoln County, Missouri, including residents of Troy, Moscow Mills, Winfield, Elsberry, Hawk Point, Foley, Old Monroe, Silex, Whiteside, and surrounding communities. It explains how Missouri DWI laws work, what occurs after an arrest, common legal issues that arise during criminal investigations, and the importance of obtaining experienced legal counsel early in the process.

While this guide provides educational information about Missouri DWI law, it is not intended to replace individualized legal advice. Every criminal case presents unique facts and legal issues that should be evaluated by a qualified attorney.

Why This Guide Was Created

Many websites discussing DWI charges focus primarily on advertising legal services. While obtaining experienced legal representation is important, individuals facing criminal charges also deserve accurate, understandable information about the legal process.

Understanding Missouri DWI Laws

Being arrested for Driving While Intoxicated (DWI) can be overwhelming, especially if it is your first experience with the criminal justice system. Understanding how Missouri law defines DWI, how prosecutors build these cases, and what legal standards apply can help you make informed decisions throughout the process.

Although many people refer to these offenses as “DUI” (Driving Under the Influence), Missouri law generally uses the term Driving While Intoxicated (DWI). Throughout this guide, both terms are used because many individuals searching for legal information use the term DUI, even though Missouri statutes refer to DWI.

What Is Driving While Intoxicated?

Under Missouri law, a person may be charged with DWI if the prosecution alleges that the individual operated a motor vehicle while intoxicated or impaired by alcohol, controlled substances, prescription medications, or a combination of substances.

A DWI case is not determined solely by a chemical test. Prosecutors may rely on several types of evidence, including:

• The officer’s observations.
• Driving behavior before the traffic stop.
• Statements made by the driver.
• Field sobriety testing.
• Breath or blood test results.
• Body-worn camera footage.
• Dash camera recordings.
• Witness testimony.
• Physical evidence collected during the investigation.

Every case is evaluated on its own facts. No single piece of evidence automatically determines the outcome.

The Burden of Proof

One of the most important principles in every criminal case is that the burden of proof rests entirely with the prosecution.

A DWI arrest is not a conviction.

The prosecutor must prove every required element of the offense beyond a reasonable doubt. Throughout the criminal process, the accused remains presumed innocent unless and until proven guilty in court.

This distinction is important because many people mistakenly assume that an arrest means they will automatically be convicted. That is not how the criminal justice system works.

Alcohol Is Not the Only Basis for a DWI Charge

Many people believe DWI charges only involve alcohol.

Missouri law also permits DWI prosecutions based on alleged impairment caused by:

• Prescription medications.
• Controlled substances.
• Illegal drugs.
• Certain over-the-counter medications.
• Combinations of alcohol and drugs.

These cases often involve complex medical and toxicological issues that require careful evaluation of laboratory testing, medical records, and expert opinions.

What Happens After an Arrest?

Following a DWI arrest in Lincoln County, several legal processes may begin.

These often include:

• Criminal charges filed through the appropriate court.
• Administrative driver’s license proceedings.
• Court appearances.
• Discovery of the prosecution’s evidence.
• Pretrial motions.
• Plea negotiations, where appropriate.
• Trial if necessary.

Every case follows its own timeline depending upon the facts and procedural issues involved.

The Role of Evidence

Evidence is the foundation of every DWI prosecution.

Common evidence includes:

Officer Observations

The arresting officer will typically document observations such as:

• Odor of alcohol.
• Bloodshot or watery eyes.
• Slurred speech.
• Difficulty maintaining balance.
• Admissions regarding alcohol consumption.
• Driving behavior before the stop.

These observations become part of the police report but should always be evaluated alongside the rest of the evidence.

Field Sobriety Testing

Field sobriety tests are investigative tools intended to assist law enforcement officers in determining whether additional investigation is appropriate.

These tests are not perfect and may be affected by factors such as:

• Medical conditions.
• Prior injuries.
• Uneven pavement.
• Weather conditions.
• Improper instructions.

Because of these variables, field sobriety testing should be considered within the context of the entire investigation.

Chemical Testing

Chemical testing may involve:

• Breath testing.
• Blood testing.
• Urine testing in limited circumstances.

Testing procedures are governed by legal and scientific standards. An attorney may review whether those procedures were followed and whether the resulting evidence is reliable and admissible under Missouri law.

Constitutional Protections

Individuals accused of DWI retain important constitutional rights throughout the criminal justice process.

These protections include:

Fourth Amendment

Protection against unreasonable searches and seizures.

Legal issues may arise concerning:

• The legality of the traffic stop.
• Searches of the vehicle.
• Probable cause for arrest.

Fifth Amendment

Protection against compelled self-incrimination and certain custodial interrogation issues.

Depending on the circumstances, statements made during an investigation may become subject to legal review.

Sixth Amendment

Individuals charged with criminal offenses have the right to legal counsel and other procedural protections throughout the prosecution.

Understanding these rights helps ensure that important legal decisions are made with appropriate advice and guidance.

Missouri’s Implied Consent Law

Missouri has an implied consent law that applies to certain chemical testing after a lawful DWI arrest. Depending on the circumstances, refusing a requested chemical test may have consequences related to your driving privileges under Missouri law.

The legal and practical effects of a refusal depend on the facts of the case and should be evaluated individually. If you have questions about implied consent, breath testing, or administrative license proceedings, an attorney can explain how these laws apply to your specific situation.

Every DWI Case Is Different

No two DWI cases are exactly alike.

Some cases focus on the legality of the traffic stop.

Others involve scientific questions about chemical testing.

Some depend heavily upon witness testimony.

Others involve constitutional issues or procedural compliance.

Because every investigation is unique, legal advice should always be based on the specific facts of the case rather than assumptions or experiences from another person’s situation.

Attorney Thomas R. Kissell carefully reviews the evidence, applicable Missouri law, and each client’s individual circumstances before recommending a defense strategy. The goal is to provide practical legal guidance, protect the client’s rights, and ensure that every case receives the attention it deserves.

What Happens After a DWI Arrest in Lincoln County, Missouri?

Being arrested for Driving While Intoxicated (DWI) can be one of the most stressful experiences a person will ever face. Many individuals arrested for DWI have never been charged with a crime before and are uncertain about what happens next. Understanding the process can help reduce anxiety and allow you to make informed decisions during every stage of your case.

While every case is different, most DWI prosecutions in Lincoln County follow a similar path. Knowing what to expect allows you to better prepare for court appearances, understand important deadlines, and work with your attorney to protect your legal rights.

Step One: The Traffic Stop

Most DWI investigations begin with a traffic stop.

Law enforcement officers may stop a vehicle for many reasons, including:

• Speeding
• Failure to maintain a single lane
• Equipment violations
• Running a stop sign or traffic signal
• Reckless driving
• Reports from another motorist
• Investigating a motor vehicle accident

Under the Fourth Amendment to the United States Constitution, an officer generally must have a lawful reason to stop a vehicle. Whether that legal standard was met is one of the first issues an attorney may evaluate during a DWI case.

In Lincoln County, traffic stops frequently occur on heavily traveled roadways including:

• S. Highway 61
• Missouri Highway 47
• Missouri Highway 79
• State Route C
• State Route W
• Rural county roads
• Streets within Troy, Moscow Mills, Winfield, Elsberry, Hawk Point, and surrounding communities

Because each traffic stop is unique, the legality of the stop should always be evaluated based on the specific facts of the case.

Step Two: The Officer’s Investigation

After making contact with the driver, the officer typically begins gathering information.

This investigation may include observations regarding:

• Speech
• Coordination
• Appearance
• Odor of alcohol
• Driver’s license and registration
• Statements made by the driver
• Physical condition

The officer may also ask questions about:

• Alcohol consumption
• Prescription medications
• Medical conditions
• Recent activities
• Travel plans

It is important to remember that the investigation is part of the evidence-gathering process.

Step Three: Field Sobriety Tests

If the officer believes additional investigation is necessary, standardized field sobriety tests may be requested.

These commonly include:

Horizontal Gaze Nystagmus (HGN)

The officer observes involuntary eye movement while the driver follows a stimulus.

Walk-and-Turn Test

The driver is instructed to take a series of heel-to-toe steps before turning and returning.

One-Leg Stand Test

The driver is asked to balance on one foot for a specified period while following instructions.

Although these tests are widely used, performance may be affected by many factors unrelated to alcohol impairment, including medical conditions, injuries, age, fatigue, weather, footwear, and uneven pavement.

For that reason, Attorney Thomas R. Kissell carefully reviews how these tests were administered and whether the officer’s conclusions are supported by the available evidence.

Step Four: Chemical Testing

Following an arrest, an officer may request a chemical test.

Depending on the circumstances, testing may involve:

• Breath testing
• Blood testing
• Urine testing in limited circumstances

Chemical testing can provide important evidence, but it is only one part of a DWI investigation.

A complete review may examine:

• Whether proper testing procedures were followed.
• Whether testing equipment was properly maintained.
• Whether the sample was handled appropriately.
• Whether documentation is complete.
• Whether scientific or medical issues affect the interpretation of the results.

Step Five: Booking and Release

Following an arrest, individuals are generally transported for booking.

Depending upon the circumstances, this process may include:

• Fingerprinting
• Photographs
• Collection of identifying information
• Bond determination
• Release pending future court appearances

The length of time a person remains in custody depends upon several factors, including the nature of the charges, prior criminal history, and bond conditions.

Step Six: Criminal Charges

After the investigation, the prosecuting attorney reviews the available evidence before proceeding with formal criminal charges.

Depending upon the circumstances, charges may involve:

• First-offense DWI
• Repeat DWI
• Felony DWI
• DWI involving an accident
• Other alcohol-related traffic offenses

Every criminal charge must ultimately be proven beyond a reasonable doubt.

Step Seven: Administrative Driver’s License Proceedings

Many people are surprised to learn that a DWI case actually involves two separate legal matters.

The first is the criminal prosecution.

The second may involve administrative action affecting driving privileges through the Missouri Department of Revenue.

These proceedings operate independently of one another. Because important deadlines may apply, it is advisable to discuss driver’s license issues with an attorney as soon as possible after an arrest.

Step Eight: Court Appearances

Most DWI cases require one or more court appearances.

Depending upon the circumstances, these may include:

• Arraignment
• Case management conferences
• Discovery proceedings
• Motion hearings
• Plea discussions
• Trial
• Sentencing, if necessary

Each stage serves a different purpose, and the timeline varies from case to case.

Step Nine: Building Your Defense

One of the most important stages begins long before trial.

Attorney Thomas R. Kissell conducts a detailed review of the available evidence, which may include:

• Police reports
• Body-camera recordings
• Dash-camera footage
• Dispatch records
• Witness statements
• Chemical test documentation
• Laboratory records
• Applicable Missouri statutes
• Relevant court decisions

Rather than assuming every DWI case should be handled the same way, each case receives an individualized legal evaluation.

Potential legal issues may involve:

• The legality of the traffic stop.
• Whether probable cause existed for the arrest.
• Constitutional protections.
• Reliability of chemical testing.
• Accuracy of field sobriety testing.
• Credibility of witnesses.
• Compliance with Missouri law.

This process helps identify strengths, weaknesses, and possible legal strategies based on the specific facts of the case.

Step Ten: Resolution

Every DWI case reaches a resolution, but not every case reaches the same resolution.

Depending upon the facts and evidence, a case may conclude through:

• Negotiated plea agreements.
• Dismissal when supported by the law and facts.
• Trial before a judge or jury.
• Other lawful resolutions permitted under Missouri law.

No attorney can ethically promise a particular outcome. Instead, the goal is to provide knowledgeable legal advice, protect the client’s constitutional rights, and pursue the best available strategy based on the facts of the case.

Why Early Legal Representation Matters

The period immediately following a DWI arrest is often the most important.

Evidence may still be available.

Witness memories are fresh.

Video recordings may need to be preserved.

Administrative deadlines may already be running.

Consulting an attorney promptly allows time to review the evidence, explain the legal process, identify potential defenses, and begin preparing your case.

At Kissell Law Group LLC, Attorney Thomas R. Kissell works closely with clients throughout Lincoln County, including Troy, Moscow Mills, Winfield, Elsberry, Hawk Point, Foley, Silex, Old Monroe, and surrounding communities. Every client receives individualized attention, clear communication, and representation focused on protecting their rights under Missouri law.

Building a Strong Defense in a Lincoln County DWI Case

Every DWI case is unique. No single defense applies to every situation, and no attorney should promise a specific result before carefully reviewing the facts. The strength of a defense depends on the quality of the evidence, the circumstances surrounding the traffic stop, and whether law enforcement followed the legal and constitutional requirements that apply during a criminal investigation.

At Kissell Law Group LLC, Attorney Thomas R. Kissell approaches every DWI case with one guiding principle: careful preparation matters. A thorough review of the evidence often identifies important legal issues that might otherwise be overlooked.

Every Case Begins With the Evidence

One of the most common misconceptions is that an arrest automatically leads to a conviction.

That is not how Missouri’s criminal justice system works.

Instead, prosecutors must prove each element of the charge beyond a reasonable doubt using admissible evidence.

Before recommending any legal strategy, Attorney Thomas R. Kissell carefully evaluates the evidence available in the case.

That review may include:

• The officer’s incident report.
• Body-worn camera recordings.
• Dashboard camera footage.
• Witness statements.
• Dispatch recordings.
• Laboratory reports.
• Breath or blood testing documentation.
• Applicable Missouri statutes and court decisions.

Only after reviewing the complete picture can an attorney provide meaningful advice regarding potential legal issues and available options.

Was the Traffic Stop Lawful?

Every DWI investigation begins with a traffic stop or an accident investigation.

Under both the United States Constitution and Missouri law, law enforcement officers generally must have a lawful basis for stopping a vehicle.

Examples may include:

• A traffic violation.
• Observed unsafe driving.
• Equipment violations.
• A motor vehicle accident.
• Information provided by another officer or witness.

A defense attorney may review whether the available evidence supports the reason for the stop and whether the officer acted within constitutional limits.

Was There Probable Cause to Make an Arrest?

A lawful traffic stop does not automatically justify an arrest.

Before placing someone under arrest for DWI, law enforcement generally must have probable cause based on the totality of the circumstances.

Factors often considered include:

• Driving behavior.
• Officer observations.
• Statements allegedly made by the driver.
• Performance during field sobriety testing.
• Chemical test results, if available.
• Other evidence gathered during the investigation.

Attorney Thomas R. Kissell evaluates whether the evidence, viewed as a whole, supports the arrest under Missouri law.

Reviewing Police Reports

Police reports are important documents, but they should never be accepted without careful review.

The report may contain:

• The officer’s observations.
• Descriptions of the driver’s behavior.
• Statements attributed to witnesses.
• Results of field sobriety testing.
• Chemical testing information.
• Details regarding the arrest.

Whenever possible, these reports should be compared with other available evidence.

If a body camera recording, dash camera video, or witness statement differs from the written report, those differences may become significant during the defense of the case.

Video Evidence Can Be Extremely Important

Many law enforcement agencies now use body-worn cameras and dashboard cameras.

These recordings often provide valuable context that written reports cannot fully capture.

Video evidence may help clarify:

• Weather conditions.
• Road conditions.
• Traffic conditions.
• Officer instructions.
• Driver responses.
• Field sobriety testing.
• The timing of important events.

Sometimes the recordings support the officer’s report.

Other times, they raise questions that deserve additional investigation.

Witnesses Matter

Passengers, bystanders, and other motorists sometimes observe part of a DWI investigation.

Depending upon the circumstances, witness testimony may help explain:

• The driver’s condition.
• The events leading to the stop.
• The officer’s interactions.
• Environmental conditions.
• Statements made during the investigation.

Each witness should be evaluated individually based upon credibility and the specific facts observed.

Constitutional Issues

Constitutional protections exist to ensure that criminal investigations are conducted fairly and lawfully.

Depending upon the circumstances, legal issues may involve:

Fourth Amendment

Questions concerning:

• The legality of the stop.
• Probable cause.

Fifth Amendment

Issues relating to:

• Custodial questioning.
• Certain statements made during the investigation.
• Due process protections.

Sixth Amendment

Questions involving:

• The right to legal counsel.
• Criminal proceedings.
• Fair trial protections.

Every constitutional issue depends upon the specific facts of the case.

Scientific Evidence Requires Careful Review

Scientific evidence often plays an important role in DWI prosecutions.

However, scientific evidence should always be evaluated carefully.

Potential areas of review include:

• Breath testing procedures.
• Blood testing procedures.
• Instrument maintenance records.
• Laboratory documentation.
• Chain of custody.
• Sample preservation.
• Operator certification.
• Scientific interpretation of the results.

Not every irregularity affects the admissibility of evidence, but careful review may identify issues that deserve further legal analysis.

Looking at the Entire Investigation

No experienced defense attorney evaluates only one piece of evidence.

Instead, the entire investigation should be reviewed together.

Questions often include:

• Why was the vehicle stopped?
• What did the officer actually observe?
• Does the video support the written report?
• Were standardized procedures followed?
• Are witness statements consistent?
• Does the scientific evidence support the prosecution’s allegations?
• Were constitutional protections respected?

Looking at the case as a whole often provides a more complete understanding than focusing on any single fact.

Every Defense Strategy Should Be Individualized

One-size-fits-all legal advice rarely serves clients well.

Some cases involve constitutional questions.

Others involve scientific evidence.

Some depend primarily upon witness credibility.

Others involve procedural issues or legal interpretation.

For that reason, Attorney Thomas R. Kissell develops defense strategies based on the unique facts of each client’s case rather than applying the same approach to every DWI charge.

The objective is straightforward: provide knowledgeable legal representation, explain available options clearly, and protect each client’s rights throughout every stage of the criminal justice process.

Preparing for the Next Step

Once the evidence has been thoroughly reviewed, the next stage involves evaluating one of the most important aspects of many DWI prosecutions: chemical testing.

In the next chapter, we’ll explain how breath testing works in Missouri, how breath test evidence is used in court, common misconceptions about breath testing, and why careful review of testing procedures is often an important part of preparing a DWI defense.

Understanding Breath Testing in Missouri DWI Cases

One of the most common pieces of evidence in a Missouri DWI prosecution is a breath alcohol test. Many people assume that a breath test result automatically determines whether someone is guilty of driving while intoxicated. In reality, breath testing is only one part of the evidence, and like any scientific procedure, it must be conducted in accordance with legal requirements and accepted testing protocols.

Understanding how breath testing works—and its limitations—can help individuals better understand the issues that may arise during a DWI case.

What Is a Breath Test?

A breath test is designed to estimate the amount of alcohol present in a person’s breath and use that measurement to estimate blood alcohol concentration (BAC).

In Missouri, approved breath-testing instruments are used by trained operators who follow procedures established by state regulations. These tests are commonly administered after a person has been arrested for DWI.

Breath test evidence is often presented alongside other evidence, including:

• Officer observations.
• Driving behavior.
• Field sobriety testing.
• Witness testimony.
• Video recordings.
• Statements made during the investigation.

A breath test is one piece of evidence—not the only evidence—in a criminal case.

What Is Blood Alcohol Concentration (BAC)?

Blood Alcohol Concentration (BAC) is a measurement of the amount of alcohol present in a person’s bloodstream.

For most adult drivers in Missouri, a BAC of 0.08% or higher may be used by the prosecution as evidence under Missouri law. Different legal standards may apply to commercial drivers and drivers under the legal drinking age.

However, a DWI charge is not based solely on a BAC number. Prosecutors may also rely on evidence of impairment, including driving behavior, officer observations, and other evidence gathered during the investigation.

How Breath Testing Is Performed

Before administering a breath test, officers are expected to follow established procedures designed to promote reliable testing.

Depending on the circumstances, those procedures may include:

• Confirming the testing instrument is approved for use.
• Following required observation procedures.
• Operating the instrument according to training and applicable regulations.
• Recording the test results.
• Maintaining required documentation.

Because breath testing is a scientific process, compliance with applicable procedures is important to the reliability of the results.

Factors That May Affect Breath Test Results

Although breath-testing technology has advanced significantly, several factors may affect the interpretation or reliability of breath test evidence.

Depending on the circumstances, these factors may include:

• Instrument maintenance and calibration.
• Operator training.
• Environmental conditions.
• Certain medical conditions.
• Mouth alcohol contamination.
• Timing of the test.
• Documentation errors.

Not every issue will affect the admissibility of a breath test, but these are examples of factors that an attorney may review when evaluating the evidence in a particular case.

Reviewing Breath Test Evidence

A thorough review of breath-testing evidence often includes examining the documentation associated with the test.

Depending on the case, Attorney Thomas R. Kissell may review:

• Maintenance and inspection records.
• Test administration records.
• Instrument documentation.
• Officer reports.
• Applicable regulations.
• Video evidence documenting the testing process.

The purpose of this review is to determine whether the evidence supports the prosecution’s allegations and whether any legal or factual issues require additional investigation.

Breath Tests Are Not the Only Evidence

Many people believe that a breath test determines the outcome of a DWI case.

That is not accurate.

Missouri courts consider all of the admissible evidence presented in a case.

For example, prosecutors may rely on:

• Officer testimony.
• Driving behavior.
• Witness observations.
• Field sobriety testing.
• Chemical testing.
• Video recordings.
• Physical evidence.

Likewise, the defense evaluates all available evidence when preparing a legal strategy.

No single piece of evidence should be viewed in isolation.

Common Misconceptions About Breath Testing

“If I failed a breath test, I will automatically be convicted.”

Not necessarily.

A breath test is one piece of evidence. The prosecution must still prove every element of the offense beyond a reasonable doubt, and the defense may evaluate whether the evidence was obtained and presented in accordance with Missouri law.

“Breath tests are always perfect.”

No scientific testing method is infallible. Like other forms of scientific evidence, breath testing depends on proper equipment, training, procedures, and documentation.

“If my BAC was below 0.08%, I cannot be charged.”

Not necessarily.

Depending on the circumstances, Missouri law permits prosecutors to rely on evidence of impairment in addition to chemical test results. The facts of each case determine what evidence may be presented.

Why Careful Review Matters

Every DWI case should be evaluated individually.

Attorney Thomas R. Kissell carefully reviews all available evidence—not just breath test results—to determine whether legal or factual issues may affect the prosecution’s case.

That review may include:

• Constitutional issues.
• Police procedures.
• Scientific evidence.
• Witness testimony.
• Video evidence.
• Applicable Missouri law.

Careful preparation allows clients to understand the strengths and weaknesses of the evidence before making important legal decisions.

Looking Ahead

While breath testing is one of the most common forms of scientific evidence in Missouri DWI cases, some investigations involve blood testing instead.

Blood testing presents different legal, scientific, and procedural issues.

Understanding Blood Testing in Missouri DWI Cases

Although many Missouri DWI cases involve breath testing, some investigations require a blood sample instead. Blood testing is commonly used when an officer suspects impairment from drugs, when a breath test is unavailable or impractical, or when additional scientific testing is necessary.

Blood test evidence often plays an important role in DWI prosecutions, but like every other type of evidence, it should be evaluated carefully and within the context of the entire case.

When Is a Blood Test Requested?

A blood sample may be requested under several circumstances, including:

• The officer believes alcohol alone does not explain the driver’s condition.
• The investigation involves suspected impairment by prescription medication or controlled substances.
• A serious traffic accident has occurred.
• A breath sample cannot be obtained.
• Additional testing is considered appropriate under Missouri law.

Every investigation is different, and the circumstances surrounding a blood draw may affect how the evidence is evaluated.

How Blood Samples Are Collected

Blood testing differs significantly from breath testing because it requires collecting and preserving a physical sample.

Depending upon the circumstances, trained medical personnel may collect the sample using procedures intended to reduce contamination and preserve the integrity of the evidence.

Documentation typically accompanies the sample throughout the testing process.

This documentation may include:

• Collection date and time.
• Identity of the person collecting the sample.
• Transfers between individuals.
• Laboratory receipt.
• Testing information.
• Storage records.

Maintaining accurate documentation helps preserve the integrity of the evidence throughout the testing process.

Laboratory Analysis

After collection, the blood sample is generally analyzed by a laboratory using accepted scientific procedures.

Depending upon the circumstances, laboratory testing may evaluate:

• Alcohol concentration.
• Controlled substances.
• Prescription medications.
• Other substances relevant to the investigation.

Laboratory reports often become important evidence during criminal proceedings.

Chain of Custody

One important concept in blood-testing cases is the chain of custody.

Chain of custody refers to the documentation showing how the blood sample was collected, transferred, stored, and analyzed.

Proper documentation helps establish that the sample tested by the laboratory is the same sample collected during the investigation.

When reviewing a case, an attorney may examine whether the available records adequately document the handling of the evidence. Whether any issue affects admissibility or the weight of the evidence depends on the specific facts and applicable law.

Sample Preservation

Blood samples should be handled and stored according to accepted procedures.

Depending upon the circumstances, documentation may include information concerning:

• Collection methods.
• Storage conditions.
• Laboratory receipt.
• Testing procedures.

Reviewing these records helps ensure that the testing process can be evaluated accurately.

Prescription Medication Cases

Not every DWI investigation involves alcohol.

Some cases involve allegations that prescription medications affected a person’s ability to safely operate a motor vehicle.

Examples may include medications prescribed for:

• Pain management.
• Sleep disorders.
• Seizure disorders.
• Other medical conditions.

Taking medication exactly as prescribed does not automatically prevent a DWI investigation if impairment is alleged. These cases often require careful evaluation of medical records, prescription information, toxicology results, and the surrounding circumstances.

Drug-Related DWI Investigations

Drug-related DWI cases often differ from alcohol-related cases.

Unlike alcohol, where a BAC measurement may be available, drug-related cases frequently require interpretation of laboratory findings together with other evidence.

Prosecutors may rely on:

• Officer observations.
• Driving behavior.
• Toxicology reports.
• Witness testimony.
• Other available evidence.

Because these cases often involve complex scientific questions, consultation with qualified experts may be appropriate in some circumstances.

Reviewing Blood Test Evidence

Attorney Thomas R. Kissell carefully reviews blood-test evidence as part of a comprehensive evaluation of every DWI case.

That review may include:

• Collection procedures.
• Laboratory documentation.
• Chain of custody records.
• Toxicology reports.
• Applicable Missouri law.
• Other evidence gathered during the investigation.

Rather than focusing on a single document or laboratory result, the goal is to understand how the evidence fits within the overall case.

Blood Testing Is Only Part of the Investigation

A blood test does not automatically determine the outcome of a criminal case.

Like every other form of evidence, blood-test results are considered together with:

• Police reports.
• Witness testimony.
• Video recordings.
• Physical evidence.
• Field sobriety testing.
• Officer observations.
• Constitutional and procedural issues.

Each piece of evidence should be evaluated within the context of the entire investigation.

Why Early Review Matters

Blood-test cases often involve scientific records that require careful examination.

Consulting an attorney early allows time to obtain records, evaluate laboratory documentation, review applicable Missouri law, and determine whether additional investigation may be appropriate.

Every DWI case deserves an individualized review based on its specific facts, the available evidence, and the applicable law.

Understanding Field Sobriety Tests in Missouri DWI Cases

One of the first questions many people ask after a DWI arrest is whether they “failed” a field sobriety test. Television shows and movies often portray these tests as definitive proof of intoxication, but in reality, field sobriety tests are investigative tools that officers use as part of a larger DWI investigation.

Performance on these tests does not automatically determine whether someone is guilty or innocent of a criminal offense. Instead, the results are considered together with all of the other evidence collected during the investigation.

Attorney Thomas R. Kissell carefully reviews field sobriety testing as part of every DWI case because the way the tests were administered—and the conditions under which they were performed—may become important during the defense of the case.

What Are Field Sobriety Tests?

Field sobriety tests are physical and cognitive exercises used by law enforcement officers to help evaluate whether further investigation for impaired driving is appropriate.

The three standardized field sobriety tests most commonly used in DWI investigations are:

• Horizontal Gaze Nystagmus (HGN)
• Walk-and-Turn Test
• One-Leg Stand Test

These tests were developed to provide officers with a standardized method of making observations during roadside investigations.

They are investigative tools—not medical examinations.

Horizontal Gaze Nystagmus (HGN)

During the HGN test, the officer asks the driver to follow a moving object—such as a pen or small flashlight—with their eyes.

The officer observes involuntary eye movement while the eyes track the object.

The officer records observations according to standardized procedures.

Although HGN testing is widely used, interpretation requires proper administration and training.

Walk-and-Turn Test

The Walk-and-Turn Test requires a driver to:

• Listen to instructions.
• Walk heel-to-toe along an imaginary or designated straight line.
• Turn using a prescribed method.
• Return in the opposite direction.

The officer observes whether the driver follows instructions and completes the task according to the standardized procedure.

This test evaluates divided attention because it combines physical movement with the ability to process and remember instructions.

One-Leg Stand Test

During the One-Leg Stand Test, the driver is instructed to raise one foot while counting according to the officer’s directions.

The officer observes factors such as balance, coordination, and the driver’s ability to follow instructions.

Like the other standardized field sobriety tests, this exercise is intended to assist the officer during the roadside investigation.

Factors That May Affect Performance

Many factors unrelated to alcohol consumption may influence how a person performs during field sobriety testing.

These may include:

• Age
• Prior knee injuries
• Back problems
• Hip problems
• Arthritis
• Neurological conditions
• Inner ear disorders
• Vertigo
• Fatigue
• Anxiety
• Stress
• Poor lighting
• Rain
• Snow
• Ice
• Uneven pavement
• Gravel roads
• High heels or restrictive footwear
• Obesity
• Certain prescription medications

Because every person is different, performance should always be considered within the context of the entire investigation.

Roadside Conditions Matter

Field sobriety tests are frequently administered outdoors.

Environmental conditions may affect performance.

Examples include:

• Heavy traffic
• Passing vehicles
• Wind
• Darkness
• Flashing emergency lights
• Cold temperatures
• Wet pavement
• Uneven shoulders
• Loose gravel
• Construction zones

Lincoln County includes rural highways, county roads, residential streets, and commercial areas, all of which present different roadside environments.

Conditions on Highway 61 may differ substantially from conditions on a rural road outside Hawk Point or Silex.

These differences may become relevant when evaluating how testing was performed.

Medical Conditions

Many medical conditions may affect balance or coordination without indicating alcohol impairment.

Examples include:

• Diabetes
• Multiple sclerosis
• Parkinson’s disease
• Recent surgery
• Head injuries
• Chronic pain
• Vestibular disorders

If a driver has a medical condition that may affect physical performance, it is important for an attorney to understand those circumstances when reviewing the case.

Following Standardized Procedures

Field sobriety tests are intended to be administered according to standardized procedures.

Attorney Thomas R. Kissell carefully reviews available evidence to determine whether the officer:

• Explained the instructions clearly.
• Demonstrated the test when appropriate.
• Allowed the driver an opportunity to ask questions.
• Selected an appropriate testing location.
• Recorded observations accurately.
• Followed accepted procedures.

Video recordings often provide valuable information during this review.

Body Camera and Dash Camera Review

Modern technology has changed how DWI cases are evaluated.

When available, body-camera and dash-camera recordings may provide additional information regarding:

• The officer’s instructions.
• The driver’s responses.
• Environmental conditions.
• The testing surface.
• Traffic conditions.
• The overall interaction.

These recordings often help place written police reports into context.

Common Misconceptions

“If I failed the field sobriety tests, I will be convicted.”

Not necessarily.

Field sobriety testing represents only one part of the evidence considered during a DWI prosecution.

The prosecution must still prove every required element of the offense beyond a reasonable doubt.

“Field sobriety tests are perfect.”

No.

Like other investigative tools, field sobriety tests have limitations.

Performance may be affected by numerous physical, environmental, and medical factors unrelated to alcohol impairment.

“Everyone performs the same.”

No.

Every individual has different physical abilities, medical histories, and life experiences.

What may be easy for one person may be difficult for another.

For that reason, field sobriety testing should always be evaluated within the context of the entire investigation.

How Attorney Thomas R. Kissell Reviews Field Sobriety Testing

Every DWI case receives an individualized review.

Depending on the circumstances, Attorney Thomas R. Kissell may examine:

• Police reports.
• Officer training records when relevant.
• Body-camera recordings.
• Dash-camera footage.
• Witness statements.
• Medical issues affecting performance.
• Weather conditions.
• Road conditions.
• Applicable Missouri law.

The objective is not to assume that any single issue determines the outcome of the case.

Instead, the goal is to carefully evaluate the evidence, identify potential legal issues, and provide clients with informed advice based upon the facts of their individual case.

Key Takeaways

• Field sobriety tests are investigative tools, not definitive proof of intoxication.
• Performance may be influenced by medical, environmental, and physical factors unrelated to alcohol or drug impairment.
• Video evidence, police reports, and witness statements should be reviewed together to understand the complete circumstances of the investigation.
• Every DWI case should be evaluated individually based on the totality of the evidence.

Frequently Asked Questions

What is the difference between a DUI and a DWI in Missouri?

Missouri law uses the term Driving While Intoxicated (DWI). Many people use the term DUI (Driving Under the Influence) when searching online, but both terms are commonly used to describe impaired driving offenses. Throughout this guide, “DWI” is used as the primary legal term because it reflects Missouri law.

Should I hire an attorney after a DWI arrest?

Every case is different, but a DWI charge can have significant legal and personal consequences. An attorney can explain the charges, review the evidence, protect your constitutional rights, and advise you on the legal options available based on your specific circumstances.

What should I do immediately after being arrested?

After a DWI arrest, you should:

• Keep all paperwork you receive.
• Write down everything you remember about the traffic stop.
• Avoid discussing your case on social media.
• Attend all scheduled court appearances.
• Contact an attorney promptly to discuss your rights and any important deadlines.

Will I lose my driver’s license?

Driver’s license consequences depend on the facts of the case and applicable Missouri law. Administrative proceedings involving driving privileges may be separate from the criminal case, and important deadlines may apply.

What happens if I refuse a chemical test?

Missouri’s implied consent law may affect your driving privileges if you refuse certain chemical testing after a lawful arrest. The legal consequences vary depending on the circumstances, so you should discuss your specific situation with an attorney.

Can my DWI charge be dismissed?

Some cases are resolved through dismissal, while others proceed through plea negotiations or trial. Whether a dismissal is possible depends on the facts, the evidence, and applicable Missouri law. No attorney can ethically guarantee a particular outcome.

How long does a DWI case usually take?

The timeline varies depending on the complexity of the case, court scheduling, discovery, motions, and other factors. Some cases resolve relatively quickly, while others require additional time if hearings or a trial are necessary.

Can a first-time offender go to jail?

Missouri law authorizes a range of penalties for DWI offenses, and the outcome depends on the facts of the case, prior history, and applicable law. Not every first-offense DWI results in incarceration.

Can prescription medications lead to a DWI charge?

Yes. Missouri law permits DWI charges based on alleged impairment from alcohol, controlled substances, prescription medications, or a combination of substances. Taking medication as prescribed does not automatically prevent a DWI investigation if impairment is alleged.

What evidence is commonly used in a DWI case?

Evidence may include:

• Police reports.
• Officer testimony.
• Body-camera recordings.
• Dash-camera video.
• Witness statements.
• Field sobriety test observations.
• Breath or blood test results.
• Laboratory reports.
• Photographs and other physical evidence.

Are field sobriety tests always accurate?

Field sobriety tests are investigative tools that may be affected by medical conditions, injuries, age, weather, fatigue, uneven surfaces, and other factors. They are only one part of the evidence considered in a DWI case.

Can I refuse field sobriety tests?

Whether field sobriety tests are voluntary and the legal implications of refusing them can depend on the circumstances. Because these issues are fact-specific, it is best to discuss them with an attorney familiar with Missouri DWI law.

What happens at my first court appearance?

The first court appearance is often an arraignment or an initial hearing. The court may advise you of the charges, discuss your rights, and address scheduling or procedural matters. Your attorney can explain what to expect based on your case.

How much does it cost to hire a DWI attorney?

Attorney’s fees vary depending on the complexity of the case, whether expert witnesses are needed, and whether the matter proceeds to trial. During a consultation, Kissell Law Group LLC can explain its fee structure and available payment options.
