How they work

Scottish Daily Mail - - The Brexmas Election -

IN-CAR breathal­y­sers are widely used in Aus­tralia and the United States.

Known as ‘al­co­hol in­ter­lock de­vices’, or al­colocks, they are fit­ted to dash­boards and re­quire a clean breath sam­ple be­fore start­ing up.

The en­gine will not fire up if the sam­ple is over the limit. Driv­ers can only take a re-test after a cer­tain amount of time.

In-built chips can no­tify po­lice when a driver fails a test or if the ma­chine has been tam­pered with.

Re­peat breath tests at ran­dom in­ter­vals stop the driver from us­ing a sober friend to start the car. They also pre­vent drink­ing once the ve­hi­cle has started.
