Roadside breathalysers to tackle drink drivers in UK

The UK government has pledged £350,000 to the Parliamentary Advisory Council for Transport Safety to run a competition for companies to develop roadside evidential breathalysers.

The government’s stated aim is to prevent offenders who are marginally over the drink-drive limit from sobering up before reaching the police station where they are tested for evidence in court.
