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.

Required Fees

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

  1. Restricted interlock license fee, and  
  2. Reinstatement fees.

IID Installation

All court-ordered installations of ignition interlock devices must be performed by DPS-certified service centers. The Regulatory Services Division of DPS certifies locations that can install and service the devices.

Driver Eligibility Status

For individuals who are required to submit compliance documents (i.e. certificate of completion, SR-22, etc.), their driver eligibility status will change from “ineligible” to “eligible” on the License Eligibility website once all documents have been processed and fees have been paid.
