Texas Ignition Interlock Laws and Compliance
Texas is known for going big. However, when it comes to alcohol, going big can lead to serious consequences. The legal BAC (blood alcohol content) limit is .08 percent. If anyone is found driving under the influence with a BAC above that limit, they risk a variety of penalties. There are administrative and financial penalties including license suspension and fines. Some offenders may be able to regain their license if they agree to install an ignition interlock device. If an ignition interlock device is ordered, the Department of Public Safety (DPS) is notified via court order. Then, the offender has 30 days to install an IID from an approved provider. ADS is an approved provider, and all approved providers are listed on the Texas DPS website.
The TX Ignition Interlock Program
In Texas, some drivers can receive a restricted ignition interlock device license, which allows them to drive as long as they install an ignition interlock device.

What Happens if I Refuse to Take a BAC Test in Texas?

How Do I Regain Driving Privileges in Texas?
Texas allows some offenders to regain their driving privileges if they meet certain criteria and agree to install an ignition interlock device from an approved provider.
Other Criteria Include:
- Offender should currently hold a Texas driver’s license that is not expired
- Their driver’s license cannot be suspended, revoked, cancelled, or denied for any reason other than the DWI offense
- Offender must submit the restricted interlock fee
- Driver must have an IID installed by an approved provider like ADS
- Show proof of appropriate insurance coverage
- If a driver's license is suspended, in addition to the DWI requirement, offenders may be eligible for an Occupational Driver's License. Check with the court or your attorney to see if you are eligible.
- Offenders may have to serve out a required portion of their suspension, up to two years
- May have to pay a $100 reinstatement fee
Offenders will receive a court order if they are required to install an interlock device. Prior to September1, 2023, judges had discretion to require an IID. As of September, 1, 2023, they still have limited discretion. However, in DWI cases an IID is often required to obtain an ODL.

What is an Ignition Interlock Device?
