Interventions to reduce road traffic injuries: reducing drink-driving
Situation and trends
Drink–driving increases the chance of a road traffic crash, as well as the likelihood that death or serious injury will result. The risk of impairment starts at very low levels of alcohol consumption and rises exponentially with alcohol intake. Drivers with a BAC of between 0.02 g/dl and 0.05 g/dl have at least a three times greater risk of dying in a vehicle crash.
Only 34 countries, representing 2.1 billion people, have national drink–driving laws in line with best practice, i.e., BAC limit of less than or equal to 0.05 g/dl as well as lower limits of less than or equal to 0.02 g/dl for young and novice drivers.
