Black's Law Dictionary Definition

A DWI is Driving While Intoxicated. This is when your blood alcohol content (BAC) is above the legal limit and you are operating a vehicle. There are two different types of DWI in the state of Missouri. Visit the State of Missouri's web page on the description of violations and consequences for DWI.

"When an individual is stopped/arrested upon probable cause that they were driving a vehicle while their blood alcohol level was over the legal limit, two separate sections of Missouri law govern the arrest and suspension/revocation of the driving privilege:


Criminal Alcohol Law

This law deals with the ticket that was issued. If an individual is convicted of an alcohol offense, the court sends a copy of the conviction to the department, and the proper points are assessed to the individual’s driving record. Subsequently, an individual's driving privileges may be suspended or revoked for accumulation of points.

Administrative Alcohol Law

This law initiates a suspension or revocation of the driving privilege if an individual's blood alcohol content level is over the legal limit. This is an automatic suspension/revocation (unless appealed and won through the Administrative Hearing or Trial De Novo process) even if the ticket was disposed of in court or reduced to a lesser charge."
