What is the primary function of an Ignition Interlock Device?

The primary function of an Ignition Interlock Device is to prevent starting the vehicle when alcohol is detected. This device is installed in vehicles operated by individuals who have been convicted of driving under the influence (DUI) or similar offenses. The ignition interlock requires the driver to submit breath samples before starting the vehicle, and if the device detects a certain level of alcohol, the vehicle will not start.

This system is designed to deter individuals from driving while impaired and to promote safe driving behavior by ensuring that only those who are sober can operate the vehicle. The use of an ignition interlock has been shown to reduce repeat offenses and enhance overall road safety by directly addressing the issue of impaired driving.
