Ignition Interlock Devices

A restricted interlock license authorizes an individual to operate a motor vehicle equipped with an ignition interlock device (IID). Upon payment of the required fees, the Texas Department of Public Safety (DPS) will issue a restricted interlock license. A restricted interlock license will not be issued if the individual’s current driver license is expired, suspended or if the individual has not paid the required fees.

Cancellation of Driver License

When DPS receives a court order restricting an individual’s ability to operate a motor vehicle equipped with an IID, the individual’s driving privilege will be cancelled unless a restricted interlock license is obtained. The cancellation takes effect on the 30th day from the date DPS sends notice to the individual. This cancellation can be removed once DPS receives a court order or vendor removal form signed by a judge or county clerk.

To obtain a restricted interlock license, individuals must pay the following fees:

  1. Restricted interlock license fee, and
