When the law says you have to be sober before driving, a Breath Alcohol Ignition Interlock Device is installed.
You don’t technically blow, it’s more humming into the machine, and for longer than you may think. And it knows if it’s not you humming, and someone is trying to start the car for you.
It’s wired to the ignition.
Okay all clear, put it in drive and go. Then it will go off at random times, and the driver will have to blow clear again before they can continue.
It logs a record of when the car was started, and the driver must regularly meet with an officer to ensure things match up.
Kind’ve like – we’ll trust you but, you’ll still have to prove and account for things.
