The risk of impairment starts at very low levels of alcohol consumption and rises exponentially with alcohol intake. Drivers with a blood alcohol concentration (BAC) of between 0.02 gdl and 0.05 gdl have at least a three times greater risk of dying in a vehicle crash. This risk increases to at least six times with a BAC between 0.05 gdl and 0.08 gdl, and rises exponentially above 0.08 gdl.
