Ignition Interlock Devices

A restricted interlock license authorizes you to operate a motor vehicle equipped with an ignition interlock device (IID). When the Department receives a court order restricting your ability to operate a motor vehicle equipped with an IID, your driving privilege will be cancelled unless an IID is obtained and installed on your vehicle and/or any vehicle you use, and restricted interlock license is obtained. The cancellation takes effect on the 30th day from the date the Department provides you with notice.

To obtain a restricted interlock license, you must comply with the following:

  1. Your Texas driver license must not be expired;
  2. Your Texas driver license must not be suspended, revoked, cancelled, or denied for any other reason;
  3. You must submit the restricted interlock license fee; and
  4. Any outstanding Reinstatement fees, for processing.

All reinstatement fees can be paid online, however the restricted interlock license fee must be submitted to the Department by mail for processing.  For your convenience, you may submit both the restricted interlock license fee and any reinstatement fees owed together to the following address for processing:  

Texas Department of Public Safety
ATTN Central Cash Receiving
PO BOX 15999
Austin, Texas 78761

You must include their name, date of birth and driver license number on all documents so their record can be properly identified. Once the Department has received your request for an interlock license, including all necessary payments, please allow 21 business days for processing.

Ignition Interlock Device Installation

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

Removal of Ignition Interlock Device

The ignition interlock can only be removed upon receipt of a court order with a court seal or vendor removal form signed by a judge or county clerk. To have the ignition interlock requirement removed from your driver license, submit the necessary documentation to the Department by mail, email, or fax.  Include your full name, date of birth and driver license number on all documents submitted and include a copy of their suspension notice if available so your driver record can be identified. Please allow 21 business days for processing.
