If you've been charged or convicted of a DUI or DWI in Texas the court may require you to have and Ignition Interlock Device (also known as an IID) installed in your vehicle.  Only vendors approved by the Texas Department of Public Safety are allowed to install and monitor these devices. Every IID installer is different and may have different pricing or devices and it's worth speaking to several to determine what meets your requirements. We've complied the approved providers for Texas to make it as easy as possible for you to get back on the road.
