Missouri DOR Administrative DWI Penalties

When you are arrested on suspicion of a DUI, your MO driver's license will be suspended.

You will have 15 days after receiving your Notice of Suspension/Revocation of Driving Privilege (Form 2385) to contest your driver's license suspension. You can use the form to either request a hearing or request restricted driving privileges.

Mail your hearing request to the address on the form. There are several options on the form so it is important to read the Rights and Responsibilities section carefully.

For more information, please contact the Missouri DMV:

If the MO DOR administrative suspension decision is upheld, your driver's license may be suspended for:

  • 90 days, if you have no prior DWI offenses.
  • 1 year, for a second conviction.

If you have a second conviction within 5 years your driver's license can be denied for up to 5 years.

If you refuse a BAC test your driver's license can be suspended for 1 year. For more information, please contact the Missouri DMV.

Court Penalties for a DWI

  • Up to 6 months imprisonment.
  • A maximum fine of $500.
  • Alcohol treatment/addiction evaluation programs.

Administrative Penalties Following a Conviction

The Department of Revenue penalties are in addition to any and all requirements set forth by a court conviction. Once you are convicted in court though, the Department of Revenue penalties will increase to:

  • For a 1st offense DWI, you may face a driver's license suspension for 90 days.
  • For a 2nd offense within any period of time, you may face a driver's license revocation for 1 year.

Missouri Ignition Interlock

Depending on the circumstances of your DWI, the court may require you to have an ignition interlock device installed in your vehicle.

An ignition interlock device hooks up to your vehicle's ignition and requires you to take a breath BAC test before starting your car. Having this device will require an installation fee as well as a maintenance fee.

For more information please contact the Missouri DOR.

  • Complete an alcohol treatment and addiction evaluation program.
  • Pay a reinstatement fee.
  • Complete any necessary driver's license tests.
  • Provide an SR22 proof of financial responsibility (generally 3 years).
