Texas Interlock Laws

Texas law mandates that individuals convicted of certain driving offenses under the Penal Code sections 49.04-49.08. must have an Ignition Interlock Device installed on their vehicles. For Texas DWI offenders, the courts may require you to install and maintain an Ignition Interlock Device (IID) in your vehicle as a condition of bond. The device must be obtained at the individual’s expense unless the court deems otherwise, and it must remain installed for the entirety of the suspension period. 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.
