Article 17.441 of the Texas Code of Criminal Procedure requires a magistrate to order a defendant being released on DWI 2nd or Felony DWI bond to install an ignition interlock device on any vehicle he owns or has access to.

What’s an ignition interlock device? From the statute:

…a device that uses a deep-lung breath analysis mechanism to make impractical the operation of a motor vehicle if ethyl alcohol is detected in the breath of the operator

The condition will be imposed on anyone arrested for DWI with a prior conviction, whether the defendant is released on personal bond, cash or cash deposit bond, surety or bail bond. In Austin, the judge that orders the condition will require a meeting with the County Pretrial Services office within 24 hours of release. The person is then given 30 days to show proof that the interlock has been installed.

Failure to install the device will result in two consequences. First, the bond will be revoked, which will result in a warrant for the person’s arrest. And second, if DPS does not receive proof of compliance, along with another fee, the person’s license will be suspended until such proof is shown.
