What Is An Ignition Interlock Device?
An ignition interlock device connects to a motor vehicle ignition system and measures the alcohol content in the breath of the operator. The device prevents the vehicle from being started until the motorist provides an acceptable breath sample.
If ignition interlock is ordered by a court, the system must be installed on each vehicle the motorist owns or operates. The device must remain installed for at least six months. The ignition interlock restriction will be added to the driver license record even if the license is revoked. The restriction will appear on the back of the driver license document as “interlock device”.
