If you were recently arrested for your first driving while intoxicated (DWI) offense in St. Charles or St. Louis, your first thought is likely about your freedom. You may be picturing a jail cell and wondering how this will impact your job, your family, and your reputation in the community. At Bert Fulk, Attorney at Law, we help people through this exact situation every day. While Missouri law does allow for jail time even for a first-time offense, the final result of your case depends on the details of the arrest, your prior history, and the quality of your legal representation.
In Missouri, a first-time DWI is typically classified as a Class B Misdemeanor. This is a criminal charge that carries specific maximum penalties under state law. It is important to remember that these are the maximums, not necessarily what happens in every case.
While six months in jail is the legal limit, it is not the standard outcome for most people. Many first-time offenders are able to avoid jail time entirely if their case is handled properly from the beginning.
In many St. Charles County cases, a primary goal is to secure a Suspended Imposition of Sentence, commonly known as an SIS. This is often the best-case scenario for someone who has never been in trouble before.
If you receive an SIS, the court places you on probation for a set period, usually two years. During this time, the court "holds" your sentence. If you successfully complete all the terms of that probation, no conviction is entered on your permanent criminal record. This is a favorable outcome because it keeps your record clean and ensures you stay out of jail.
However, probation is not just "getting off easy." You must follow strict rules, or the judge can revoke the SIS and sentence you to jail. Common requirements for DWI probation in Missouri include:
Even for a first-time offender, certain "aggravating factors" can change how a prosecutor or a judge views your case. If these factors are present, the state may push for a jail sentence rather than probation.
If your BAC was significantly over the .08% limit, such as .15% or higher, the court may view the offense as a higher risk to public safety. At higher levels, Missouri law can require more intensive treatment or even a short "shock" jail stay as a condition of probation.
If your driving caused a car crash, the situation changes immediately. Even if the injuries were minor, the presence of an accident makes it much harder to argue for a simple SIS. If someone was seriously hurt, the charge could even be elevated to a felony.
Having a minor in the car at the time of the arrest is a major red flag for the court. This can lead to additional charges, such as endangering the welfare of a child, which carries its own set of jail time and fines.
The police report is the first thing a prosecutor reads. If the report says you were combative, disrespectful, or tried to flee the scene, they will be less likely to offer a lenient plea deal.
Just because you were arrested does not mean you will be convicted. We look at every piece of evidence to find flaws in the state's case. Often, the evidence the police think is "solid" is actually based on mistakes or faulty equipment.
The Fourth Amendment protects you from unreasonable searches and seizures. An officer must have a valid legal reason to pull you over. If they pulled you over based on a "hunch" rather than a specific traffic violation or reasonable suspicion of a crime, the stop may be illegal. If the stop is thrown out, everything that happened after—including the breath test—is usually thrown out as well.
Officers often use three standard tests: the Horizontal Gaze Nystagmus (eye test), the Walk and Turn, and the One-Leg Stand. These tests are highly subjective. They are often given on uneven pavement, in the dark, or in the rain. Factors like your age, weight, footwear, or a past medical injury can make these tests nearly impossible to pass, even for someone who hasn't had a drop to drink.
The machines used at the station, like the DataMaster or Alco-Sensor, are not foolproof. They must be calibrated every 35 days. If the maintenance logs show that the machine was not checked on time, or if the officer was not properly certified to use it, the results can be challenged in court. You can read more about this on our DWI practice page.
When people ask about jail, they are often unaware of the massive financial burden a DWI conviction carries. Over a few years, a first-time DWI can cost you well over $10,000. This includes:
One of the most important things to know is that your criminal case in court is separate from the case regarding your driver's license. When you are arrested, the officer usually takes your plastic license and gives you a 15-day driving permit.
If you do not request an administrative hearing with the Department of Revenue within those 15 days, your license will be suspended automatically, regardless of what happens in court. We can file this request for you to make sure you keep your ability to drive while we fight the criminal charges.

The legal system moves quickly, and the choices you make in the first few days after an arrest can impact the rest of your life. At Bert Fulk, Attorney at Law, we stand between you and the state to ensure your rights are protected.
