Texas Ignition Interlock Requirements

Texas drivers risk administrative and financial penalties if they are convicted of Driving While Intoxicated (DWI). For many drivers, a Texas state-approved ignition interlock device will be required in order to regain driving privileges. Intoxalock is a Texas approved ignition interlock provider and our devices meet all state criteria.

The Texas Interlock Program

Texas refers to drunk driving or alcohol-based driving offenses as DWI, and penalties include fines, jail time, and license suspension. The legal limit for drivers is below .08% BAC, but those with lower BAC may still find themselves facing consequences depending on the circumstances of the incident. Some offenders are able to regain driving privileges by installing a Texas state-approved ignition interlock device from an approved ignition interlock provider. This guide will explain the interlock policy in Texas.

How Can I Get My Driving Privileges Back in Texas?

  • Serve out required probation period
  • Install an ignition interlock device from an approved provider like Intoxalock

Intoxalock Texas Ignition Interlock Devices

Intoxalock is an approved ignition interlock device provider in Texas. This means that the state has reviewed and approved the device and determined it to be reliable and meet state criteria. Testing data is shared with the appropriate state monitoring authority.

What is an Ignition Interlock Device?

Ignition interlock devices are also known as car breathalyzers or IIDs. They are installed into a vehicle’s ignition system and require testing before a driver can start their car.

  • Driver must pass a breath alcohol content (BrAC) test and pass or the vehicle will not start
  • Multiple test failures in a row may result in a device lockout, which will require customer service assistance
  • Failing the test multiple times in a row can result in a lockout
  • All failures are reported to the state’s monitoring authority
  • During most trips, the IID will request random retests to prevent tampering and make sure the driver stays sober

How long is a Texas Interlock device required?

This will be clarified in court, but typically interlock devices are required throughout the entire license suspension period, and occasionally longer. If you are unsure, contact your attorney, the court, or your state department of motor vehicles for clarification.

The Process: What to Expect

    Seek guidance from a DUI lawyer to understand your legal options and rights following a DUI violation.

  2. Get an Assessment

  3. Obtain Proof of SR-22 Insurance, If Required

    If applicable, provide proof of financial responsibility and insurance coverage with an SR-22 certificate.

  4. Schedule Interlock Install

    Speak to our State Specialists to schedule your IID installation to meet court or state requirements.

  5. Regular Monitoring

    Your ignition interlock usage will be regularly monitored to maintain compliance with legal requirements.

    After fulfilling your IID requirement and receiving approval from your monitoring authority, you can arrange to have your ignition interlock device removed at your local service center.
