Calls for repeat drink driving offenders to have breathalyser installed in vehicles

Repeat drink driving offenders may soon be required by law to have breathalyser installed in their vehicles.

The small breath-testing machines, known as ignition interlock devices, prevent motorists starting their vehicles if they are over the limit for alcohol consumption.

Professor Denis Cusack, director of the Medical Bureau of Road Safety, called for changes in the law for repeat offenders, noting that alcohol is a contributory factor in almost a third of all road traffic crashes.

He said these devices would prevent drivers from starting their cars, vans or trucks, which in turn would have a positive impact on road safety.

The devices require the driver to blow into the machine using a mouthpiece. If the presence of alcohol above the limit is detected, the engine won’t start.

According to Prof Cusack, all new cars manufactured in the EU since 2022 are capable of being fitted with the devices.

The Department of Transport is currently considering recommendations on their use.
