Texas Ignition Interlock DUI Laws

Texas law usually allows you to drive immediately and avoid suspension by installing an ignition interlock. Your probation or parole officer will advise you of any pretrial need for an ignition interlock.

If you are convicted of a DWI in Texas (a court finds you guilty or you enter a plea agreement), you will be subject to jail time. Penalties are enhanced for multiple offenses and operating under the influence with a child passenger. Visit TXDOT.gov for detailed information.

A restricted interlock license authorizes you to operate a motor vehicle equipped with an ignition interlock device (IID). When the department receives a court order restricting your ability to operate a motor vehicle equipped with an IID, your driving privilege will be canceled unless an IID is obtained and installed on your vehicle and/or any vehicle you use, and a restricted interlock license is obtained. The cancellation takes effect on the 30th day from the date the department provides you with notice.

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

Benefits of installing an interlock as early as possible: The incentive is obtaining driving privileges. 

Interlock Process

To check the status of your driver’s license or to determine if you are eligible for reinstatement, visit the Texas License Eligibility website. This page will provide you with information on what you will need to reinstate your driver’s license or driving privilege, including any fees you may owe. Once all compliance items have been processed and your mandatory suspension period has ended, your driver eligibility status will be updated to reflect “eligible”.

How do I get an interlock license?

  • When released on bond (pre-trial bond), if ordered to install IID by the state of Texas, call LifeSafer within 24 hours to schedule an immediate installation. You may only have 72 hours in some courts to install the device. Proceed to Step 4 if this applies to you.

  • If you were not ordered upon bond release, upon conviction you will need an interlock device. Call LifeSafer Ignition Interlock at 800-634-3077 to schedule your ignition interlock installation. Ask about discounts and special offers. We can schedule install appointments around your court appearance and you can cancel anytime if you are not convicted.

  • After conviction, you will be ordered to have an interlock for probation. Call LifeSafer Ignition Interlock at 800-634-3077 immediately to schedule installation as soon as possible.

  • For your convenience, submit both the restricted interlock license fee and any reinstatement fees owed together to the following address for processing:

    Texas Department of Public Safety ATTN Central Cash Receiving
    PO BOX 15999
    Austin, Texas 78761

    You must include your name, date of birth, and driver’s license number on all documents so your record can be properly identified. Once the department has received your request for an interlock license, including all necessary payments, please allow 21 business days for processing.
