ignition interlocks

An ignition interlock is a small device installed in a vehicle that measures the driver's blood alcohol concentration (BAC) before allowing the engine to start. To operate the vehicle, the driver must blow into the device and breathe below a preset alcohol level. If alcohol is detected above that limit, the vehicle won't start. This technology helps prevent intoxicated driving, often as a court-mandated measure for DUI offenders. It ensures the driver is sober at the start and during operation, promoting safer roads and reducing alcohol-related accidents.
