What is a DWI/DUI Charge?

A DWI (Driving While Intoxicated) or DUI (Driving Under the Influence) charge is a serious legal offense in Missouri, indicating that a driver is accused of operating a vehicle while impaired by alcohol or drugs.
A person is typically charged with DWI if their blood alcohol content (BAC) is 0.08% or higher, which is the legal limit for drivers over 21. For those under 21, the state has a zero-tolerance policy, meaning any detectable level of alcohol can lead to a DUI charge. The charge not only covers alcohol but also impairment due to other substances, including prescription medications and illegal drugs.
Being charged with DWI/DUI means facing potential legal consequences such as fines, license suspension, and even jail time, depending on the severity of the offense and whether it’s a first-time or repeat violation. These charges also carry administrative penalties, including points on your driving record and mandatory participation in substance abuse programs.

The Legal Process for DWI/DUI Cases in Missouri

Understanding and navigating the legal process for DWI/DUI charges while having a knowledgeable DWI/DUI attorney by your side is vital for anyone facing such charges in Missouri. Here are the most critical steps of this challenging process:

Traffic Stop and Arrest

The process starts with a traffic stop where law enforcement must have probable cause for suspecting impairment, leading to an arrest.

BAC Testing

After the arrest, the individual undergoes Blood Alcohol Content (BAC) testing to determine the level of alcohol or drugs in their system.

Filing of Charge

If the BAC is over the legal limit or there's evidence of impairment, DWI/DUI charges are formally filed against the individual.


The accused is read their charges and asked to enter a plea during the arraignment.

Pre-trial Motions and Hearings

This phase may involve legal arguments, evidence presentation, and plea negotiation between the defense and prosecution.


If no plea agreement is reached, the case goes to trial, where evidence is presented before a judge or jury.

Legal Representation

Throughout the process, having an experienced DWI/DUI attorney is crucial to challenge evidence and provide a strong defense.

EXTREMELY HAPPY!! Big $$$ incoming!!We ended up with seriously about 3 times more than I honestly... thought we’d get by the end of it! Life changing! The real deal! Not a big giant corporation that cannot remember your name every time you see them! From the moment I walked in to honestly just “shop” around for the right attorney for my situation. I could just feel the connection right away. I am usually a GREAT body and communicative analyzer, I could tell by the end of our first conversation that I’d put my life In his hands. And I did, and he did not disappoint.I had an intrinsically more difficult case that any lawyer would have had nightmares about! Gene, Taylor, and the crew quite literally make it look like a cake walk! If you trust the process, trust in Gene as he is very professional, not pushy at all, communicative, very compassionate and down to earth! I had no idea what I was in for, being that we had to take the road less traveled on account of my situation.Gene told me from the start that it would take a 18-36 months to get this done. I took Genes word as Bible. Did exactly as he said when he said it, “tried” not to bother them too much asking for updates (it’s so hard but he does update you if there are things to actually update on right away). Followed the plan step by step and I’m living proof that Gene and the crew will pull the impossible out of their hats given the opportunity! He’s been in this business for a long long time, knows how it works, speaks with such confidence and knowledge, that I will NEVER go anywhere else for my attorney needs. Missouri Injury law firm as a whole was such a great experience for me!!!!! Recommending to everyone I know ! Thank you Gene I owe you a bottle of wine or two !read more

In the context of St. Louis, Missouri, the terms DUI (Driving Under the Influence) and DWI (Driving While Intoxicated) are often used interchangeably to describe the offense of operating a vehicle while impaired by alcohol or drugs. However, under Missouri law, the term DWI is more commonly used. Both terms refer to the criminal act of driving a vehicle while impaired to the degree that the driver’s ability to operate the vehicle is diminished. The key difference is more terminological than legal in Missouri, as the state statutes primarily refer to the offense as DWI.

Several defenses can be used to challenge a DWI/DUI charge. Some of the most common defenses include:

  • The Breathalyzer test was not calibrated properly.
  • Police officer did not have probable cause to stop you.
  • Your blood alcohol content (BAC) was below the legal limit.
  • You were not driving the vehicle.
  • You were not in control of the vehicle.

If you are arrested for DWI/DUI, the most important thing to do is to remain calm and cooperative. Do not argue with the police officer, and do not make any statements that could be used against you. If you have been arrested, it is important to contact an attorney as soon as possible. To find a DWI lawyer in St Louis, look no further than Missouri Injury Law Firm – your trusted DUI attorney St Louis.

Yes, if you’ve been charged with a DWI in St. Louis, MO, it is highly advisable to consult with a local lawyer like Missouri Injury Law Firm. DWI charges can have serious consequences, including fines, license suspension, and even jail time. Lawyers specialized in DWI cases can provide critical advice, represent you in court, negotiate with prosecutors, and potentially help you reduce the charges or penalties. An experienced attorney can also navigate the complexities of Missouri’s DWI laws, advocate for your rights, and work towards the best possible outcome in your case.

In some cases, it is possible to get a DWI/DUI charge dismissed. However, the chances of getting a DWI/DUI charge dismissed are much higher if you have a good defense attorney who can build a strong case on your behalf.

Yes, in some cases, a DWI/DUI charge can be reduced to a lesser offense. This is often done through plea bargaining, which is a negotiation between the prosecution and the defense attorney. In a plea bargain, the defendant agrees to plead guilty to a lesser offense in exchange for a lighter sentence.

A DWI/DUI ignition interlock device (IID) is a device that is installed in a vehicle’s ignition system to prevent a person with a DWI/DUI conviction from driving while intoxicated. The IID requires the driver to blow into a breathalyzer before starting the vehicle. If the driver’s BAC is above the legal limit, the vehicle will not start. IIDs are often ordered by courts as part of DWI/DUI sentences.

In Saint Louis, as in the rest of Missouri, the legal limit for blood alcohol content (BAC) is 0.08% for drivers 21 years and older operating regular passenger vehicles. For commercial drivers, the legal limit is lower, at 0.04%. Drivers under the age of 21 are subject to Missouri’s “Zero Tolerance” law, which means any detectable amount of alcohol in their system (0.02% BAC) can result in a DWI charge.

In St. Louis, Missouri, drivers have the right to refuse a breathalyzer test; however, refusal comes with significant consequences due to Missouri’s implied consent law. This law states that by operating a vehicle in the state, drivers have given their implied consent to submit to alcohol and drug testing if suspected of DWI. Refusal to take a breathalyzer test can lead to automatic license revocation for one year, regardless of whether you were ultimately found guilty of DWI. Additionally, refusal can be used as evidence against you in court. Given these implications, it’s important to consider the consequences of refusal and to seek legal advice from a qualified DWI lawyer in St. Louis.

Our local law firm understands the challenges and complexities of DWI cases and is committed to advocating for our clients’ rights and interests throughout the legal process.
