Drunk driving has become a huge social stigma in the UK over the past few decades. People will report drunk drivers, even their friends and relatives, as they see it is a social good. They still exist but the incidence of it has deceased rapidly. Scotland has just reduced the drink drive alcohol limit even further to the point where you effectively can't have any alcohol all day if you're driving. Given the mention of the Swedish rate between tests and positive results for breathalysers I imagine they have the same laws as the UK. The police in the UK can breathalyser anyone: a) who has committed a moving traffic offence b) involved in a road traffic collision c) who the officer suspects of having alcohol (any) in their system Most police forces require their officers to breath test if they have grounds, and while many police officers don't like dealing with traffic offences almost all of them will go out of their way to stop drink drivers. Given almost every driver commits a moving traffic offence every so often there is pretty much always grounds to test anyone (you don't have to actually prosecute for the offence, i.e. crossing a mini roundabout, just over the speed limit etc).
