Texas Ignition Interlock Laws

For DWI offenders, Texas courts may require you to install and maintain an Ignition Interlock Device (IID) in your vehicle as a condition of bond. This requirement will be up to the discretion of the Judge or mandatory based on the following:

  • This is your first offense – discretion of Judge
  • You had a breath alcohol concentration (BAC) level of .15 or higher – discretion of Judge
  • A subsequent arrest was made – mandatory

As a condition of probation, an IID may be required. This requirement will be up to the discretion of the Judge or mandatory based on the following:

  • This is your first offense – discretion of Judge
  • You had a BAC level of .15 or higher or a subsequent arrest was made – mandatory
  • You’re under the age of 21 and this is your first offense and subsequent arrest was made – mandatory

*Texas IID clients can have a camera installed, per your State authority’s authorization, to take your picture while you perform a breath test.
**You will be responsible for all costs and installation services for the IID, and bring your vehicle in for regular monitoring and service. You may be required to attend and complete a DWI intervention or education program, as well as doing community service.
***Condition of Issuance for Occupational Licenses deems an Interlock mandatory for the first and subsequent offenses.
