Everyone accepts that people are less able to drive a vehicle when they have alcohol in their system. We had a BAC limit of 80 mg and it is now 50 mg, but there has been a derogation for concentrations between 50 mg and 80 mg. Is there evidence to suggest that the derogation is the cause of increased accidents and fatalities?
