Driving Behavior and Physical Condition in a DUI Case

A DUI case doesn’t start with sobriety tests, it starts with the traffic stop itself.

Why Were You Pulled Over?

Police must have a lawful reason to initiate a stop. Common reasons include:

• Drifting between lanes

• Speeding or driving unusually slow

• Sudden braking

• Rolling through stop signs or signals

If the officer lacked reasonable suspicion, that issue can become a key part of the defense.

What Officers Look For During the Stop

After pulling someone over, officers often focus on behavior, such as:

• Difficulty locating a license or insurance

• Trouble following instructions

• Speech patterns or perceived confusion

These observations are often subjective. Fatigue, stress, medical issues, or simple nervousness can look like impairment, even when alcohol is not involved.

Are Field Sobriety Tests Fair for Everyone?

Field sobriety tests are not designed for all body types, ages, or physical conditions.

For example:

• Older individuals may struggle with balance-based tests

• People with joint pain or mobility issues may have difficulty with agility tasks

• Someone who is naturally uncoordinated or anxious may perform poorly despite being sober

A larger, older, or less athletic person is far more likely to “fail” these tests than a younger, more agile individual. Officers do not always account for these differences, which can lead to unfair arrests.

How B Block Law LLC Approaches DUI Defense

At B Block Law LLC, we do not simply accept an officer’s conclusions at face value. Every DUI case requires careful review.

Our approach often includes:

• Examining whether the traffic stop was lawful

• Reviewing dash cam and body cam footage

• Evaluating how field sobriety tests were administered

• Identifying medical or physical factors that affected performance

Details matter in DUI cases, and small errors can have a major impact.

Take the Next Step

A DUI charge can affect your license, finances, and future but it should not be decided by a flawed test or assumption.

If you’ve been arrested for DUI in St. Louis or Chesterfield, getting clear information early matters.

This article pairs with an informational video explaining how field sobriety tests work and why they are often challenged in Missouri DUI cases.

If You Refuse the Test

Refusing a breath or blood test triggers a different filing and usually different license consequences.

This is known as a license revocation for refusal.

A refusal can result in:

• A one-year license revocation

• No automatic restricted driving privileges

• Stricter reinstatement requirements

Many drivers assume refusing the test avoids consequences. In reality, refusal cases often carry harsher license penalties, and the deadlines to challenge them are just as strict.

Why Deadlines Matter

In both situations—whether you blow or refuse—there are short deadlines to request a hearing with the Department of Revenue. Missing those deadlines can mean losing the opportunity to challenge the suspension or revocation altogether.

License consequences can begin before a criminal case is resolved, which is why early legal guidance matters.

Criminal Case vs. License Case

It’s important to understand:

• A DWI criminal case is handled in court

• A license suspension or revocation is handled administratively

These are two different proceedings, and the outcome of one does not automatically control the other.

St Louis DWI Lawyer: Navigating Your First DWI Charge in Missouri

When you’re faced with your first DWI charge in Missouri, it’s natural to feel overwhelmed and uncertain about what to expect. At B Block Law LLC, located at 400 Chesterfield Center #400, Chesterfield, MO 63017, our St Louis DWI lawyer, Brendan Block, is committed to guiding you through this challenging process. Here’s an overview of what you can anticipate.

Quick Answer: What to expect from your  first DWI in Missouri?

Expect to have two cases: a license case and a criminal case. The license case is
decided by a hearing officer or a civil court judge. The judge in this case can decide to
revoke your license from 90 days up to a year. The criminal case determines whether the DWI will go on your permanent criminal record or background. This case is in state or municipal court and the rules of criminal procedure and evidence apply. Here, in
criminal court, the Prosecutor is held to the high standard of proving every element of Driving While Intoxicated beyond a reasonable doubt.

The Dual Nature of DWI Cases
In Missouri, a DWI charge typically involves two separate but interconnected cases: the license case and the criminal case.

The License Case: Understanding the Stakes
The license case is an administrative proceeding, usually decided by a hearing officer or a civil court judge. The focus here is on your driving privileges. The judge has the authority to revoke your license for a period ranging from 90 days to a year, depending on the circumstances of your case. This aspect of your DWI charge can significantly impact your daily life, making it essential to have a knowledgeable St Louis DWI lawyer by your side.

The Criminal Case: Protecting Your Record
The criminal case is where the potential impact on your permanent criminal record or background comes into play. This case is handled in state or municipal court, where the rules of criminal procedure and evidence are strictly enforced. In the criminal court, the Prosecutor must meet the high standard of proving every element of Driving While Intoxicated beyond a reasonable doubt. This is where the expertise of a skilled DWI lawyer becomes invaluable.

The Role of Your DWI Lawyer
Having a competent DWI lawyer like Brendan Block is crucial in navigating both the license and criminal aspects of your DWI charge. As a seasoned St Louis DWI lawyer, Brendan brings:

Expertise in DWI Laws: With a deep understanding of Missouri DWI laws, Brendan can identify weaknesses in the prosecution’s case and advocate effectively for your rights.

Experience in Courtroom Advocacy: Brendan’s experience in both administrative and criminal courts allows him to present your case persuasively, seeking the best possible outcome.
Guidance Through the Process: From the initial stop and arrest to court proceedings, Brendan will explain each step, ensuring you understand your rights and options.

Most people charged with a DWI are concerned about one thing: how much it is going to cost. The truth is, the price of a DWI conviction in Missouri goes far beyond court fines. It can impact your job, your insurance, your driving record, and your future for years to come.

At B Block Law LLC, we work with clients across St. Louis Chesterfield and beyond in Missouri, to help them understand the full financial and personal consequences of a DWI and how to minimize the damage through a smart legal defense. Here is what every driver should know about the real cost of a DWI in 2025.

Court Fines and Legal Penalties Are Just the Beginning

For a first-time DWI in Missouri, the fine can be up to $1,000, not including court costs, probation fees, or alcohol education classes. If your BAC was above .15 percent, or if you refused to take a chemical test, you could face additional penalties including longer license suspensions or mandatory ignition interlock requirements.
Repeat offenders or drivers involved in accidents can face substantially higher fines, potential jail time, and felony charges. These outcomes carry serious financial consequences, especially when paired with long-term loss of driving privileges.
At B Block Law LLC, we work to prevent these outcomes by identifying defense opportunities early and handling both the criminal and administrative aspects of your case.

Insurance Rates Can Double—or Worse

If you are convicted of a DWI, your insurance company may reclassify you as a high-risk driver. In St. Louis and Chesterfield, that often means:

• A 100% to 200% increase in your auto insurance premiums
• A requirement to file SR-22 insurance documentation for up to three years
• Denial of coverage from some carriers altogether

Depending on your age, driving history, and provider, this can add thousands of dollars to your annual expenses. In many cases, clients end up paying more in insurance increases than they do in court fees.

Working with an experienced DWI attorney in Chesterfield or St. Louis can help you avoid a conviction and protect your driving record from triggering these rate hikes.

Lost Wages, Missed Work, and Employment Risks

Many clients underestimate how disruptive a DWI can be to their work life. If your job requires a clean driving record, commercial license, or background checks, a conviction may threaten your employment.

Even if your job does not depend on driving, court appearances, mandatory classes, and license suspension can cause you to miss work, lose income, or strain your professional reputation.

At B Block Law LLC, we understand that keeping your job is often just as important as resolving your case. We structure your defense to preserve your record, minimize court time, and protect your ability to stay employed.

Long-Term Consequences That Outlast the Case

In Missouri, a DWI conviction stays on your permanent criminal record and driving record. It cannot be expunged for at least 10 years, and even then, only under certain conditions. This can affect your:

• Housing applications
• Job interviews
• College admissions
• Professional licensing

In addition, Missouri courts take prior DWI convictions seriously. If you are ever charged again, even years later, that prior conviction will be used to enhance penalties and sentencing.

This is why many people in St. Louis and Chesterfield seek out a DWI attorney not just to resolve the current charge, but to protect their long-term options. Preventing a conviction today means protecting your future tomorrow.

You Can’t Afford the Wrong Outcome

The total cost of a DWI in Missouri often ranges from $7,500 to $15,000 when you include fines, legal fees, insurance, lost wages, and long-term financial consequences. These cases are not just about what happens in court. They are about what happens after you leave.

Hiring the right DWI attorney in St. Louis or Chesterfield, MO gives you the best chance to limit these costs, avoid a conviction, and get your life back on track without long-term damage.

Missouri’s DWI laws have evolved in 2025, and these changes could significantly affect the outcome of your case. Whether you were charged in St. Louis or Chesterfield, understanding the updates to the law—and how they are being enforced—can make all the difference.

At B. Block Law LLC, we help clients in St. Louis County and Chesterfield, Missouri, navigate DWI charges with clear strategy and experienced representation. Below, we break down what has changed and what it means for your defense.

Stricter Penalties for High-BAC and Fatal DWI Incidents

Missouri House Bill 87, introduced earlier this year, increases penalties for drivers with elevated blood alcohol content who cause serious harm. Drivers with a BAC of .15 percent or higher who are involved in fatal crashes could now face Class A felony charges. Cases involving multiple fatalities may also be prosecuted more aggressively.

If passed, this legislation will give prosecutors greater discretion to pursue felony charges—even for first-time offenders. As a St. Louis DWI attorney, B. Block Law LLC closely monitors proposed changes like these and adapts our defense strategies accordingly.

Hands-Free Law Increases DWI Traffic Stops

Missouri’s hands-free driving law, effective January 1, 2025, prohibits drivers from holding cell phones while operating a vehicle. While not a DWI-specific law, it has led to a sharp increase in traffic stops across St. Louis County and St. Charles County.

In practice, this law gives police more opportunities to initiate stops that could lead to sobriety tests or DWI arrests. If you were pulled over for phone use and then charged with a DWI, your attorney will need to examine whether the stop was lawful and whether proper procedures were followed. B Block Law LLC frequently defends clients in these scenarios throughout St. Louis and Chesterfield, Missouri.

Core DWI Law Structure Remains, but Enforcement Is Tighter

The foundation of Missouri’s DWI law has not changed. Drivers with a BAC of .08 percent or higher, or those who refuse a chemical test, still face administrative license suspensions. The penalties vary:

• 90-day suspension for a first DWI
• One-year suspension for test refusal
• Criminal penalties including fines, jail time, and possible ignition interlock requirements

While these penalties remain, they are being enforced more aggressively in 2025, particularly in St. Louis County and St. Charles County. Working with an experienced Chesterfield DWI attorney can help ensure you respond to both the criminal and administrative aspects of your case.

Ignition Interlock Requirements and Restricted Licenses

For many DWI offenses, an ignition interlock device (IID) is required before a person can regain full driving privileges. In Missouri, first-time DWI offenders with a high BAC may face mandatory IID installation for 90 days or more.

At B Block Law LLC, we help clients obtain restricted driving privileges and guide them through the compliance process. Whether your arrest happened in downtown St. Louis or the suburbs of Chesterfield, we focus on reducing long-term consequences and preserving your ability to work, drive, and support your family.

2024 has been a year marked by significant achievements and notable victories for Attorney Brendan Block of B Block Law. Serving the St. Louis and Chesterfield, MO areas, Brendan Block’s dedication, strategic acumen, and pursuit of justice have resulted in favorable outcomes for his clients across a variety of challenging cases. Below are some of the key successes that highlight his expertise and commitment to defending his clients’ rights.

2024 Accomplishments: Recent Client Successes from B Block Law 

Unlawful Use of Weapon Case: A man charged in 2022 with the felony of unlawful use of a weapon found himself in a dire situation after allegedly following another man along Highway 64 and pointing a gun at him. Initially, his bond was set at $50,000 cash only. Attorney Brendan Block intervened, successfully reducing the bond to $40,000 with only a 10% payment required, allowing the defendant to post a $4,000 bond. In a significant victory, just days before the trial in 2024, the case was downgraded to a misdemeanor peace disturbance, demonstrating Mr. Block’s effective legal strategy and advocacy.

DWIs: In another challenging scenario, a client with five DWIs within a five-year span managed to retain his driver’s license without facing the typical five to ten-year suspension. Under normal circumstances, such a record would result in a lengthy license suspension and a challenging path to reinstatement. However, through Brendan Block’s strategic defense and advocacy for his client’s treatment and rehabilitation, the client avoided severe penalties and served only 10 days in jail on weekends.

Shoplifting Cases: Brendan Block has consistently demonstrated his ability to navigate complex legal situations with skill and compassion. Over the past five years, he has handled numerous shoplifting cases, ensuring that none of his clients faced jail time. His meticulous efforts in negotiating dismissals and deferred prosecution agreements have preserved his clients’ dignity and freedom, even when the evidence of guilt appeared strong.

DWI Breathalyzer Case: One of the most restrictive penalties for a second DWI offense is the mandatory installation of a breathalyzer in the offender’s vehicle. Due to updates in the DWI statute effective from 2013, defendants can be held accountable for decades-old offenses. In 2023, a client charged with a DWI from an incident in 2008 found himself in a precarious position after another charge. Brendan Block’s adept legal maneuvering led to the exclusion of breath test results, preventing the imposition of an ignition interlock device and amending the DWI charge to a no-point violation.

Attorney Brendan Block’s accomplishments in 2024 exemplify his unwavering dedication to his clients. His ability to secure favorable outcomes in complex and challenging cases is a testament to his hard work, strategic thinking, and commitment to justice.

St Louis DWI Lawyer: Can I get my first DWI in Missouri dismissed?

At B Block Law LLC, located at 400 Chesterfield Center #400, Chesterfield, MO 63017, our dedicated team, led by the experienced St Louis DWI lawyer Brendan Block, understands the complexities and challenges of DWI cases in Missouri. If you’re facing a DWI charge, you might be asking, “Can my first DWI in Missouri be dismissed?” While dismissals are not common, they are possible under certain circumstances.

Quick Answer: 

Can I get my first DWI in Missouri dismissed? Dismissals of DWI charges are rare, but do happen. It’s important to know the odds that it is similar to hitting the jackpot at a casino as it is to get a DWI dismissed without doing depositions or setting a case for trial. Realistically, it may happen once in 100 or 200 cases. Prosecutor’s don’t give up easily due to the political and societal pressures brought by Mothers Against Drunk Driving and others. Many more common dispositions could include a deferred prosecution agreement or a reduction in the charge, but outright dismissals of cases are rare. That’s why it is important to have a competent and experienced DWI lawyer like Brendan Block, who knows the law and can weigh the cost and benefits of going to trial.

Exploring Other Possible Outcomes
In many DWI cases, more common outcomes include deferred prosecution agreements or a reduction in the charge. These alternatives are often more attainable than outright dismissals. A deferred prosecution agreement, for instance, may involve certain conditions like attending educational programs or community service, offering a pathway to potentially avoid a conviction record.

Faulty Breathalyzers and DWI Charges

Breathalyzers have historically been viewed as the black and white answer to testing suspected drunk drivers and handing out DWI charges. You can’t deny science. You’re either over or you’re under. But a recent investigation and report by the New York Times found that Breathalyzer machines employed by police departments across the nation give faulty results a significant amount of the time.

Because breathalyzer results differing by hundredths of a degree can be the difference between a jail sentence, a suspended license or heading home – their accuracy is important.

John Fusco, who ran a company in charge of making breath-testing devices, told The Times that the tests were never meant to be lone deciders of guilt or innocence.

There are many different brands, machines and technologies used as breath-testers. The Breathalyzer is one of them but has become the generic name used to refer to all testers. Police departments around the country largely employ machines that use infrared spectrometry to identify blood alcohol levels (BAC). Infrared spectrometry works by seeing how different molecules absorb infrared light and in turn determining the ethanol concentration and BAC. 

While these technologies are often tested for accuracy, results rely heavily on proper maintenance, calibration and training of the officer using the machine.

Police departments are in charge of maintaining the machines. The times investigation found that the departments lack consistent standards of maintenance and training. They also found anecdotal evidence of departments DIY-ing some of the required chemicals for the machine, leading to warped results.

Missouri DWI laws and the breathalyzer 

What does this information mean when it comes to your rights, your DWI charges and your future?

Missouri’s strict “no tolerance” DWI laws make these findings especially scary. Missouri DWI laws state that the only evidence needed to convict someone is a breathalyzer result of .08% or higher. A .15% result can lead to an “aggravated DWI” with harsher penalties. 

But if the only thing needed to convict you is faulty – where does that leave you? Missouri drunk driving laws state that citizens give “implied consent.” If you choose “chemical revocation” or refuse to blow, your license will be suspended for 1 year.

If you’re pulled over for a suspected DWI in St. Louis, your immediate options are limited. You can either blow or refuse. The real decisions come the next day. The only way to fight DWI charges, whether deserved or not, is with an experienced lawyer who practices DWI law in Missouri.

DWI charges in Missouri

There are a number of strategies to fight, and often overturn, DWI charges in Missouri. An experienced DWI lawyer will look into every aspect of your arrest – from the officer’s actions to the breathalyzer used. Understanding the common misuses of breathalyzers is extremely important in fighting charges fo driving while intoxicated. 

There are a number of questions to ask and arguments to make. Some include:

• An arresting officer improperly administering the blood alcohol concentration test
• The BAC test not being calibrated properly according to protocol 
• The driver’s medical and health issues
• Poor maintenance of the BAC test machine 
• Ignoring the “20 minute observation” rule

Block Law has experience fighting and overturning DWI charges in Missouri using a number of arguments. Brendan, who previously worked as a prosecutor, understands what prosecutors look for and how they make arguments. This makes him an expert in knowing how to fight them.

Your decision after the night in question is your best hope at winning your case. It can be the difference between a conviction going on your record or being expunged. Be sure you hire a lawyer who knows what they’re doing and genuinely cares about your case.

Brendan is an attorney who cares. He offers free consultations so you can call or message him any time.
