What Is An Interlock?

An ignition interlock prevents a vehicle from starting if the driver has been drinking alcohol.

Like a breathalyzer, an ignition interlock measures the alcohol in a person’s system. If that amount exceeds a pre-programmed level, then the interlock temporarily locks the vehicle’s ignition. To take the test, the driver simply blows into the device.
