First DWI Penalties in Missouri (2026)
Complete guide to what happens when you get your first DWI in Missouri — jail time, fines, license suspension, and what you can do about it.
Understanding First-Offense DWI in Missouri
A first-offense DWI in Missouri is classified as a Misdemeanor. While this is the least severe DWI charge, the consequences are still significant and can affect your life for years. Missouri uses a 5-year lookback period, meaning any subsequent DWI within that window will be treated as a repeat offense with harsher penalties.
Missouri uses the term DWI and has a 5-year lookback. Expungement is available for first offenses after 10 years. The BAC (Blood Alcohol Concentration) limit in Missouri is 0.08% for standard drivers, 0.04% for commercial drivers, and 0.02% for drivers under 21. Being at or above these limits creates a "per se" DWI charge — the prosecution does not need to prove impairment.
Penalties Breakdown
What Happens After a First DWI Arrest in Missouri
After being arrested for a first DWI in Missouri, you will face two separate proceedings: a criminal court case and an administrative license suspension through the DMV. Missouri has implied consent laws, meaning you automatically consent to chemical testing by driving on state roads. Refusing a test triggers additional penalties.
The criminal case will determine whether you are convicted and what sentence you receive. Meanwhile, the DMV will independently suspend your license. In many cases, you have only 10 to 30 days to request a DMV hearing to challenge the suspension. Missing this deadline means an automatic suspension.
How a DWI Attorney Can Help
An experienced DWI attorney in Missouri can challenge the traffic stop, question the accuracy of breath or blood tests, negotiate reduced charges (such as a "wet reckless"), protect your driving privileges, and minimize the long-term impact on your record. Attorney fees for a first DWI typically range from $2,000 to $5,000, but the savings in reduced penalties and protected employment can be far greater.
In Missouri, a first DWI may be eligible for expungement 10 years after completion. An attorney can advise you on the specific requirements and timeline.
