Arrested for DWI in Missouri? Here's What Happens Next

You're pulled over and suspected of drunk driving. The officer asks "have you had anything to drink?" From this point on, everything you say and do affects the outcome of your case.

The officer will ask you to submit to roadside tests or to provide a breath or blood sample. Missouri law allows you to decline field sobriety tests or to answer any questions, though failure to cooperate can be used against you in your case. Refusing a chemical test (breath, blood, or urine), on the other hand, carries stiffer penalties. Due to Missouri's Implied Consent law, refusing a breathalyzer request triggers a one‑year license revocation; and, depending on your DWI history, it could require the installation of an ignition‑interlock device on your car. Missouri law does provide you up to 20 minutes to call a DWI lawyer before deciding whether to blow.

Missouri DWI Laws Explained  

Under Missouri law, you can face DWI charges for operating a motor vehicle:  

• For having a blood alcohol concentration (BAC) above the legal limit; or  

• In an intoxicated condition when under the influence of alcohol or drugs or a combination of both.

Legal BAC Limits

These standards determine when the state can file DWI charges in Missouri, and they play a major role in how your case is evaluated. The BAC threshold is different for certain drivers. A person is considered intoxicated if their BAC is .08% or higher. However, the threshold drops for those with a CDL or under the age of 21 years old. The BAC of .04% for commercial drivers is considered “excessive”; and a BAC of .02% for drivers under the age of 21. The number of beverages a person can drink before they are over the legal limit for BAC varies from one person to another and depends on a variety of factors.   

"Operating" vs. "Driving"

It is not uncommon for motorists in Missouri to face DWI charges even when they were not seen driving the vehicle. Missouri’s DWI law prohibits operating a motor vehicle while impaired, which includes being asleep at the wheel with the key in the ignition and the engine running. The car does not have to be moving to be found guilty of DWI. Prosecutors often argue that simply having the ability to start the vehicle is enough to meet the definition of “operating.” An experienced DWI defense attorney can challenge those assumptions and argue for dismissal when there is no evidence of actual operating.

DWI Tests and Your Rights  

Field Sobriety Tests

During a DWI investigation, the police will likely administer the three standardized tests: the Horizontal Gaze Nystagmus, Walk-and-Turn, and One-Leg Stand. These tests are used to create probable cause for an arrest; however, they are known to be inaccurate and unreliable. The officer's inexperience in performing and grading the test, weather and roadside conditions, footwear, medical conditions and nervousness can all lead to failing results. Fortunately, Missouri law allows motorists to refuse a field sobriety test without risking an automatic suspension of your driver's license. While this could result in an arrest, and be used against you in court, it preserves valuable defenses.

Chemical Tests

Breath, blood, saliva or urine tests are used to measure your BAC. Under Missouri’s implied consent statute, all motorists are deemed to have consented to a chemical test. If you blow 0.08% or higher, your license is immediately suspended and you are issued a notice of suspension and 15-day temporary driving permit. You have only fifteen days to request a hearing to challenge this suspension.

The length of the suspension depends on your five-year driving record: 90 days for a first offense, and any subsequent offense where the person's immediately preceding five-year driving record does not reflect an alcohol-related enforcement contact. Otherwise, the suspension is for one year. Restricted Driving Permits (RDP) are available after serving the initial 30-Day suspension and submitting proof of SR-22 Insurance to the DOR. Those with prior DWIs will also need to show proof of an Ignition Interlock Device on their car.

Implied Consent & Refusal

The same cannot be said about refusing a breathalyzer or chemical tests in Missouri. The state adopted “implied consent” laws, which means all motorists are legally required to submit to chemical testing (breath, blood, saliva, or urine). The officer must inform you of the consequences of refusing and provide you 20 minutes to consult an attorney. Refusal can lead to a revocation of your driver’s license for one year and also mandatory installation of the ignition interlock device for six months if there is a prior DWI on your record. Upon refusal, you are issued a notice of revocation and 15-day temporary driving permit; however, you can challenge a Breathalyzer Refusal Revocation by filing a Petition for Review (PFR) within 30 days of the notice.

In many counties, including St. Louis County, the Court will issue an order staying (or pausing) the revocation of your driving privileges pending the outcome of your PFR. The DOR may confess your petition if certain conditions are met. A DWI Defense lawyer can help you file your PFR and protect your driving record.

Missouri DWI Penalties

Possible criminal penalties for DWI vary depending on two main factors: the number of prior DWI offenses on your record and the severity of the offense and circumstances. Jail time depends whether you have any prior DWI convictions or pleas of guilty. Typically, those convicted of DWI are also required to pay hefty fines and face license suspension and may be required to drive with an ignition interlock device.    

In certain cases, the court can suspend the jail sentence and impose probationary conditions under an SIS or SES. Those conditions can range from substance abuse treatment to random testing. Drivers whose license is suspended after a DWI conviction may be eligible to apply for a hardship license.   

The penalties associated with a DWI conviction in Missouri can have a significant impact on your life. Attorney Anthony Bretz can help you minimize these penalties by negotiating a plea bargain, reducing your charges, or securing a not-guilty verdict. Additionally, as a Missouri DWI attorney, he can help you explore alternative sentencing options if applicable. 

First Offense

A first DWI in Missouri is a class B misdemeanor. It carries a potential range of punishment of 1 day to 6 months in jail, a fine up to $1,000, or both. A conviction will also result in your license being suspended for 90 days, though a Restricted Driving Privilege (RPD) may be available. Administrative and criminal suspensions of your license can run back‑to‑back. You may also be ordered to attend the Substance Awareness Traffic Offender Program (SATOP) and Victim Impact Panel, complete community service, and serve up to two years of probation.

Second Offense

For a second Missouri DWI within five years, the penalties increase dramatically. You risk a conviction for a Class A misdemeanor, 10 days to one year in jail, a fine of $2,000 or a combination, and loss of your license for one to five years. Additional conditions may include 2 years of probation, continuous alcohol monitoring and extended community service. As with a first offense, you have 15 days to request a hearing to protect your license if there is a BAC or 30 days if you refused a breathalyzer.

Third & Subsequent Offenses (Felony DWI)

A third DWI in Missouri makes it a class E felony charge. A conviction can lead to a minimum of 30 days in jail or up to four years in prison, fines up to $10,000, a 10-Year Denial of your license, and supervised probation lasting five years. Even if you receive probation, Missouri law requires a minimum of one month in jail. Ignoring the administrative deadlines could cost you your driving privileges for a decade, after which you would need to petition the Court before your license could be reinstated.

The range of punishment and the minimum incarceration required before you are eligible for probation or parole increases with repeat DWI offenses. A 4th DWI involves 60 days up to 7 years in prison. a 5th DWI requires a minimum of 2 years in prison before you are eligible for parole and from 5 to 15 years total. Because of the stakes, felony DWI cases demand aggressive defense strategies and knowledge of how to negotiate charges down to a misdemeanor when possible.

DWI Penalty Overview

These are statutory ranges. Outcomes vary based on the facts of each case, plea negotiations and local court practices.

Administrative License Hearing

Separate from the criminal case is an administrative process that deals solely with your driving privileges. Once you're arrested, the Department of Revenue issues a temporary 15‑day permit. You must file a request for an administrative hearing within 15 days of the notice of suspension if you submitted to a chemical test; or you have 30 days to file a petition for review in the Circuit Court of the County where you were arrested if you refused a chemical test, though your permit is only good for the first 15 days. Missing these deadlines means automatic loss of your license.

At an administrative hearing, a hearing officer with the DOR reviews the arrest report and any evidence you present. A lawyer can subpoena the arresting officer and challenge whether the stop was legal, the basis for the arrest, whether the breath test was performed properly, and whether the instrument was calibrated, or the blood-draw procedures. Success here may prevent a suspension.

Reinstatement after a suspension requires a small Reinstatement Fee, completion of SATOP, maintenance of SR-22 Insurance for a period of two years from the starting date of the suspension, and possibly installation of an Ignition Interlock Device for six months. You have fifteen days to request a hearing to contest this suspension.

At a trial for a refusal case, a Circuit Court Judge or DWI Commissioner in St. Louis County will hear the evidence proffered by the DOR who is represented by the Prosecutor's Office. The DOR will submit the Arrest Report. A DWI Defense attorney can subpoena the arresting officer and examine or question the officer on the stand to challenge the basis for the stop, the grounds for arrest and whether the chemical test was actually refused.

Reinstatement after a revocation period requires payment of a small Reinstatement Fee, complete SATOP, maintain SR-22 Insurance for a period of two years from the starting date of the revocation, and possibly installation of an Ignition Interlock Device for six months.

Proven Defense Strategies

Illegal Stop

The Fourth Amendment protects you from unlawful searches and seizures. The officer needs reasonable suspicion to stop you, such as evidence of a traffic violation or equipment defect. A DWI attorney can get the case dismissed by showing the officer lacked the necessary reasonable suspension or probable cause. Challenging the stop requires reviewing dash‑cam and body-cam video, dispatch logs and the officer’s narrative.

Breath Test Maintenance Issues

Breathalyzers must be maintained and calibrated regularly, once every 35 days. Improper maintenance, temperature variation and device malfunctions can cause false or elevated BAC readings. Demonstrating these problems may result in suppression of the test or plea negotiations for a reduced charge.

Blood Test Challenges

Blood samples must be collected by a qualified medical professional using a collection tube containing a proper anti-coagulant, and stored and transported according to strict procedures. Chain‑of‑custody errors, fermentation or preservatives can affect the BAC result. Independent laboratory analysis often reveals discrepancies that can be used to challenge the prosecution’s evidence. Subpoenaing the blood drawer can result in testimony that establishes a lack of integrity in how the sample was collected.

Medical Conditions Mimicking Impairment

Medical conditions like inner‑ear disorders, diabetes, neurological issues, joint disorders, low-blood sugar, vision problem, etc., can produce symptoms that look similar to alcohol impairment. Presenting medical records and expert testimony can help jurors understand a defendant's behavior may be caused by issues other than alcohol or drugs.
