What is Considered a DWI in Missouri?

In Missouri, a person can be charged with Driving While Intoxicated (DWI) if they operate a motor vehicle while under the influence of alcohol, drugs, or any intoxicating substance that impairs their ability to drive safely. Most people associate DWI with alcohol, but Missouri law also applies to illegal drugs, prescription medications, and even certain over-the-counter substances if they affect your driving ability.

Under Missouri law, you may be considered legally intoxicated if your blood alcohol concentration (BAC) is 0.08% or higher while operating a motor vehicle. However, you can still be arrested and charged with a DWI even if your BAC is below that limit, as long as the officer believes your driving ability is impaired.

Law enforcement officers in St. Louis often rely on a variety of evidence when making a DWI arrest, including:

• Field sobriety tests
• Breathalyzer or blood test results
• Observations such as slurred speech, bloodshot eyes, or the smell of alcohol
• Erratic or dangerous driving behaviors

Even if you feel that you were wrongly accused, it is important to take the charge seriously and contact a qualified St. Louis DWI lawyer as soon as possible.

Missouri DWI & Implied Consent Laws

Missouri operates under what is known as an implied consent law. This means that by driving on Missouri roads, you automatically agree to submit to a chemical test—such as a breath, blood, or urine test—if a law enforcement officer has reasonable grounds to believe that you are driving while intoxicated.

If you refuse to submit to a chemical test, there can still be serious consequences. A refusal may result in:

• Automatic driver’s license revocation for at least one year
• The refusal being used as evidence against you in court
• Increased legal penalties if you are convicted

Many drivers believe that refusing a test protects them, but in some cases, it can actually make the situation worse. Understanding the nuances of Missouri’s implied consent law is complex, and this is where an experienced St. Louis DWI lawyer from The Hammer Law Firm, LLC can help explain your options and protect your rights.

DWI Penalties in MO

Missouri takes driving while intoxicated very seriously, and the penalties increase significantly with each additional conviction. Even a first-time DWI charge can have lasting effects on your criminal record, driving privileges, and financial stability.

First DWI Offense (Class B Misdemeanor)

For most first-time offenders, a DWI is charged as a Class B misdemeanor. Potential penalties may include:

• Up to 6 months in jail
• Fines of up to $1,000 plus court costs
• Driver’s license suspension for up to 6 months
• Mandatory Substance Abuse Traffic Offender Program (SATOP) or substance abuse education
• Possible probation
• Installation of an ignition interlock device (IID) in some cases
• Increased auto insurance rates

In some cases, a first-time offender may be eligible for a suspended imposition of sentence (SIS) or other alternative sentencing options, but this is not guaranteed and depends on the specific circumstances of the arrest.

Second DWI Offense (Class A Misdemeanor)

A second DWI conviction is typically charged as a Class A misdemeanor, with harsher consequences, including:

• Up to 1 year in jail
• Fines of up to $2,000
• License revocation for at least one year
• Extended use of an ignition interlock device
• Longer probation periods
• Mandatory alcohol treatment or counseling

Third DWI Offense (Class E Felony)

A third DWI is often charged as a felony in Missouri. Penalties increase significantly and may include:

• Up to 4 years in prison
• Fines of up to $10,000
• Long-term or permanent license revocation
• Mandatory use of an ignition interlock device
• Extended substance abuse treatment programs

Fourth and Subsequent Offenses (Felony Charges)

Fourth and subsequent DWI offenses are considered felony-level crimes and can result in severe, life-altering penalties, such as:

• Lengthy prison sentences
• Substantial fines
• Permanent loss of driving privileges in some cases
• Strict probation requirements
• Mandatory participation in intensive treatment programs

Aggravating Factors That Increase Penalties

Certain circumstances can lead to even harsher penalties, including:

• Extremely high BAC levels
• Causing an accident or injury
• Having a minor in the vehicle
• Driving with a suspended or revoked license

Because the penalties for DWI in Missouri escalate so quickly, it is critical to take every charge seriously. A knowledgeable St. Louis DWI lawyer at The Hammer Law Firm, LLC can evaluate your situation, explain your options, and aggressively fight to reduce or dismiss the charges whenever possible.

Legal Defenses to DWI Charges

Being charged with DWI does not mean you will be convicted. There are many possible legal defenses that may apply to your case, depending on the circumstances of your arrest.

At The Hammer Law Firm, LLC, our St. Louis DWI attorney will carefully analyze every aspect of your case, including:

• Whether the officer had valid probable cause to stop you
• Whether field sobriety tests were administered correctly
• The accuracy and calibration of breathalyzer machines
• The way blood or urine samples were collected and handled
• Violations of your constitutional rights

Improper police procedures, inaccurate test results, equipment malfunctions, and lack of probable cause can all be used to challenge the prosecution’s case against you. Our goal is to expose weaknesses in the state’s evidence and fight aggressively on your behalf.

In some cases, it may be possible to have the charges reduced, obtain a diversion program, or even get the case dismissed entirely.

FAQs About DWI in St. Paul, MN

Can I be charged with a DWI if I wasn’t driving?

In some cases, yes. If you were found in “actual physical control” of a vehicle, such as sitting in the driver’s seat with the keys in the ignition while intoxicated, you may still face charges.

Will a DWI stay on my record forever?

A DWI conviction can remain on your criminal record permanently in many cases. However, certain situations may allow for expungement or record sealing. A St. Louis DWI lawyer can help determine your eligibility.

Is it possible to keep my license after a DWI arrest?

Yes, but it depends on your specific circumstances. You may be able to request a hearing or obtain a limited driving privilege. Taking quick action is essential.

What should I do after being arrested for DWI?

Do not try to handle it alone. Contact a St. Louis DWI attorney at The Hammer Law Firm, LLC immediately. Avoid discussing your case on social media or with anyone other than your attorney.

Can I be arrested for DWI in St. Louis even if I wasn’t driving?

Yes. In Missouri, you can be charged with DWI even if the vehicle was not moving. If you are found in “actual physical control” of a vehicle while impaired—such as sitting in the driver’s seat with the keys nearby—you may still face a DWI charge.

What is Missouri’s “persistent offender” status for DWI?

A driver may be labeled a persistent offender if they have two or more DWI-related convictions. This can lead to significantly harsher penalties, including mandatory jail time and longer license revocation periods.

Can prescription medication lead to a DWI in St. Louis?

Yes. You can be charged with DWI for driving while impaired by prescription drugs, even if you have a valid prescription, if your ability to safely operate a vehicle is affected.

Will a DWI affect my job or professional license?

In many cases, a DWI can impact employment, especially for commercial drivers, healthcare workers, teachers, government employees, and those who hold professional licenses. Some employers also conduct background checks that may flag the conviction.

Do St. Louis police need probable cause to pull me over for DWI?

Yes. An officer must have reasonable suspicion to stop your vehicle and probable cause to arrest you for DWI. If your stop or arrest was unlawful, it may be possible to challenge and suppress evidence.

What happens if I miss my court date for a DWI charge?

Missing a court date can result in a warrant being issued for your arrest. It can also lead to additional charges and negatively affect your case.

How long does a DWI case usually take in St. Louis?

The process can take several months or longer depending on the court’s schedule, whether motions are filed, and whether the case goes to trial or is resolved through a plea.

Can passengers get in trouble if the driver is arrested for DWI?

Passengers are typically not charged with DWI, but they could face charges for other illegal behavior, such as public intoxication, possession of alcohol, or drug-related offenses.
