Ignition Interlock Devices

When the Department receives a court order restricting a person to the operation of a motor vehicle equipped with an ignition interlock device, the person's driver license will be cancelled unless the person obtains an interlock restricted license. The cancellation takes effect on the 30th day from the date that DPS sends notice to the subject. A cancellation can be lifted upon receipt of a court order or vendor removal form signed by the judge or county clerk.

A restricted interlock license authorizes the person to operate a motor vehicle equipped with an ignition interlock device. Upon payment of the required fee, the Department issues a restricted interlock license authorizing the person to operate a motor vehicle equipped with an ignition interlock device. A restricted interlock license will not be issued if the driver license is expired, suspended, or if the individual has not paid the required reinstatement fees.
