Tennessee DUI Laws

Tennessee Interlock Process

In order for your time with an ignition interlock device to count toward your requirement, you MUST have a restricted driver license. If you are required under T.C.A. 55-10-417 to complete an additional six (6) month requirement for two (2) DUI convictions within five (5) years, that time WILL NOT begin until you have reinstated your driving privileges and been reissued a restricted driver license.

How do I get an interlock license in Tennessee?

  • Once you are convicted of a DUI offense, request a restricted license/ignition interlock device from the Court.  The Judge signs the Order for Restricted License (ORDL).

  • Call LifeSafer Ignition Interlock at 800-634-3077.  Ask about discounts and special offers.  You may drive on the ORDL for a maximum of 10 days, allowing you time to have an ignition interlock device installed.

  • Once your ignition interlock device has been installed, allow at least forty-eight (48) hours for LifeSafer to electronically submit the proof of installation and have it post to your account in the Driver Services database before going to the Driver Services Office.  Driver Services cannot accept a paper copy of your installation report from you.

  • Take the original certified court order and a copy to a Driver Services Center to obtain a restricted license. The Driver Services Center will also require proof of interlock installation to have been submitted to electronically and an  SR-22 certificate (your insurance company can help with this). When you apply, you will be issued a 90-day restricted interim driver license. The application is then sent to the Driver Services Central Office for review and a final determination.
