On the face of it, an alcohol interlock device seems like a very good idea that should be used more than it is at present. If you have never heard of it, the device, which is fitted to cars, prevents a drunk driver starting the vehicle and is used by courts as a sentence for repeat drink drivers.
The Automobile Association says that more convicted drink drivers deserve to have this sentence imposed on them.
Offenders convicted of repeat drink-driving offences or an excessively high blood or breath alcohol concentration can be given an alcohol interlock sentence.
They can then apply for an alcohol interlock licence and have an interlock installed.
Such drivers must blow into the device - recording a breath alcohol level of zero - before their car will start. The device has certainly sparked interest on social media.
