Drink drivers get behind the wheel because they feel more sober than they actually are, a new study claims.
Drivers who have had a drink hours previously may feel sober enough to drive, but the brain functions that aid safe driving take much longer to recover.
Researchers asked subjects to raise their blood alcohol content to 0.10 per cent, at which point a driver is 52 times more likely to have an accident. They were quizzed on how drunk they felt and asked to complete an online hidden maze.
And their performance got worse as their blood alcohol levels rose.
