Introduction
Driving While Intoxicated (DWI) charges are among the most serious traffic-related offenses in Missouri. In St. Louis and across the state, a DWI conviction can impact your freedom, your finances, and even your future employment. If you’ve been arrested for DWI in Missouri, it’s critical to understand the law, your rights, and how an experienced St. Louis DWI lawyer can help you navigate the process.
What is a DWI in Missouri?
In Missouri, a DWI occurs when a driver operates a vehicle with a blood alcohol concentration (BAC) of 0.08% or higher . For commercial drivers, the limit is 0.04%, and for drivers under 21, it drops to just 0.02%.
But here’s what many drivers don’t realize: you can also be charged with DWI if law enforcement believes your ability to operate a vehicle is impaired by alcohol, prescription medication, or illegal drugs — even if your BAC is below 0.08%.
