What Happens When a Person Under 21 Gets a DWI in Missouri?
The consequences of a DWI conviction can have lifetime effects on your child. You need an aggressive and experienced lawyer who can defend your child’s rights and fight the charges.
It is important to understand that, while most Missouri drivers can operate a motor vehicle with a BAC as high as .08 without incurring an administrative license suspension, the same does not apply to those under the age of 21.
Missouri has strict DWI laws regarding offending underage drivers. There are various factors to consider such as the age of the driver and their Blood Alcohol Concentration at the time of the arrest.
Given the complexities, it is important to contact an attorney with experience representing persons under 21 who have been charged with underage DUI.
Our Experienced team of DWI attorneys have handled thousands of cases, including countless incidents involving underage consumption of alcohol.
How Underage DWI Charges Usually Start in Missouri
Most underage DWI cases begin with a routine traffic stop—speeding, a broken taillight, drifting within a lane, or leaving a party late at night. From there, an officer may look for signs of alcohol use (odor, red or watery eyes, admissions, passengers, or open containers) and may ask the driver to perform field sobriety tests.
In many cases, the officer will also request a preliminary breath test or another form of chemical testing. Even when the number is low, being under 21 can change how the situation is treated, and statements you make on the roadside can end up being used to support the charge.
That’s why the early details matter. A strong defense often starts by examining why you were stopped, whether the officer had a valid reason to expand the stop into a DWI investigation, and whether the testing procedures were handled correctly.

Frequently Asked Questions
Can you get a DWI under 21 in Missouri with a “small” amount of alcohol?
Yes. Missouri has a lower alcohol threshold for drivers under 21, and an underage drinking-and-driving situation can still lead to serious consequences even when the BAC is below the adult limit. The safest move is to treat it like a real DWI case and get legal advice quickly.
Will an underage DWI affect my driver’s license even if my criminal case is still pending?
It can. Missouri DWI situations often involve both a court case and separate license consequences handled through the Department of Revenue, and the license side can move forward on a different timeline. That’s why it’s important to address both tracks early.
Should I just plead guilty to get it over with?
Usually, no—not without speaking to a lawyer first. A quick plea can create long-term problems (license issues, insurance costs, school/work consequences, and a record that’s hard to undo). An attorney can review the stop, the investigation, and any testing to see whether the evidence can be challenged or the outcome improved.
