The Texas Transportation Code §521.2476 requires DPS establish minimum standards for vendors of Ignition Interlock Devices (IID) who conduct business in Texas and procedures to ensure compliance with those standards, including procedures for the inspection of a vendor’s facilities.
Regulatory Service Division staff approves ignition interlock devices, including the authorization of vendors to install, download, remove, repair, replace and make reports of all required data recorded by the device.
