Oklahoma Ignition Interlock DUI Laws

Information on Oklahoma’s DUI and Ignition Interlock Laws

If you are arrested for DUI in Oklahoma, the officer will immediately confiscate your license and you will be issued an affidavit that will allow you to drive for 30 days. This is an administrative action that occurs if you are driving with a blood alcohol concentration (BAC) of .08. You will face additional criminal consequences, but the administrative action is separate. You must attend both to keep driving legally. You may apply to the Oklahoma Department of Public Safety to either request a hearing or a Modified Driver’s License.  You can find the instructions and form here.

If the department is agreeable to you having a Modified Driver’s License, you will need to fill out another form and install an ignition interlock (IID) in order to drive. If you refuse a chemical test, your license will be suspended for six months and you will be required to install an ignition interlock.

In addition to these administrative sanctions, if you are convicted of DUI in Oklahoma or plead guilty, you face fines, jail time, and additional license suspension time.

Oklahoma offers treatment courts, including DUI treatment courts, that are administered by local jurisdictions. You can learn more on the Oklahoma City Treatment Court page.

Every situation and state is unique, please consult with your attorney or your state licensing authority to confirm your requirements and obligations.

How do I get an interlock license?

  • A modified driver’s license replaces your original Class D license in Oklahoma and allows you to operate a noncommercial motor vehicle as long as the vehicle is equipped with an ignition interlock device. Fill out the application to request a modified driving license as soon as possible.

  • Call LifeSafer Ignition Interlock at 800-634-3077 to schedule your ignition interlock installation. Ask about discounts and special offers! We will provide you with a certificate of installation for the interlock device (IID).

  • After you have met all the requirements of reinstatement as noted on the Order of Revocation, Oklahoma DPS will issue a restricted driver license that will indicate that the person is only authorized to operate a vehicle upon which an interlock has been installed. The wording “Ignition Interlock Device Required” will be placed on the driver’s license.
