Restricted Interlock Licenses
If you are convicted of driving under the influence of alcohol or drugs, restrictions may be placed on your driver’s license to prohibit you from operating a motor vehicle. Such restrictions may include temporary suspension, occupational license restrictions, or restriction by an interlock device. Persons who are allowed to drive a vehicle with an interlock device attached may be given a restricted license to operate their motor vehicle.
The law in Texas makes the operation of a vehicle under the influence of alcohol a very serious offense. If you have been accused of DWI, consult Dallas DWI lawyer Mark T. Lassiter at 214-457-1668 to discuss your case.
Interlock Devices
Interlock devices typically:
- Are installed in the primary vehicle of a person who has been convicted of DWI
- The device uses a breathalyzer to determine the blood alcohol content of a person getting behind the wheel
- The device is attached to the ignition of the motor vehicle
- If the device detects alcohol on the driver’s breath, the motor will not start and he or she will not be able to operate the vehicle
Persons who have an ignition interlock device installed in their vehicle may be issued a restricted driver’s license for the duration of their sentence. This license is usually given only in the event that the individual can prove a need to operate their vehicle to go to work, school, or other obligations that require the use of a vehicle.
