Mississippi Ignition Interlock DUI Laws

Information on Mississippi DUI and Ignition Interlock Laws

There are two ways your license is affected in Mississippi if you are arrested for driving under the influence.

You will face an Administrative suspension of 90 days in every case where you are arrested for DUI in Mississippi, starting 45 days from arrest. You can request an interlock restricted driver’s license for that time period to continue driving. If you refuse to take a blood alcohol concentration (BAC) test at the time of your arrest, your license will be suspended for 180 days.

For a first-time DUI conviction in Mississippi, your license will be suspended for 120 days. To continue driving instead of serving out your suspension, you can request an interlock restricted driver’s license. All suspension times start 45 days from the time your information is entered into the DPS system, once court documents have been forward.

If this is your 2nd or subsequent offense, you can only drive with an ignition interlock restricted license in a vehicle equipped with an ignition interlock device that complies with section 63-11-31. LifeSafer ignition interlocks are a compliant and approved device in Mississippi.

Interlock Process

At the time of arrest, you were given a receipt for your driver’s license. This receipt serves as a temporary permit to drive and is valid for a period of 30 days. You should contact the court and request a trial date and an extension of this driving permit.

If you do not contact the court within 30 days and obtain a court order extending your temporary permit, your driving privilege will be suspended for a period of 90 days.
