Abstract
The legal limit for drinking and driving in Britain is 80 mg /dl of alcohol in the blood. Changes in public opinion, the results of recent research, and the evaluation of other countermeasures, such as random breath testing, show that there are good grounds for revising the legal limit downwards. It is suggested that the legal limit should be reduced to 50 mg /dl and random breath testing introduced. A zero limit is proposed for learner and first year drivers.
