License Suspension & DWI

What happens to my license if I am arrested for DWI? This is a common, complicated question that can only be answered by a knowledgeable St. Louis DWI lawyer who is familiar with drunk driving laws. The answer, you may be surprised to know, depends on a number of factors that are specific to your case.

Many people are unaware that if you are arrested DWI or DUI, you face two potential cases:

  • A criminal case against you filed by the prosecuting attorney’s office in the jurisdiction where the offense occurred; and
  • A civil case against your license filed by the Missouri Department of Revenue.

Failure to represent and defend either case can have devastating consequences for you and affect your ability to operate a vehicle in the future.

Is a DUI/DWI a Felony in Missouri

In the state of Missouri, a DWI is only a felony if it charged against you more than twice.

A third DWI is considered a class D felony and is punishable by time a 4 or 5 year imprisonment. A hefty fine or a driver license revocation of up to 10 years is also enforced on certain class D felony charges.
