HC Deb 29 April 1981 vol 3 c414W
22. Mr. Michael McNair-Wilson

asked the Secretary of State for Transport in what proportion of road accidents which involve death or serious injury were drivers concerned driving with over the blood alcohol legal limit.

Mr. Kenneth Clarke

About one-third of the drivers killed in road accidents in England and Wales are found to have exceeded the legal blood alcohol limit. Comparable information on drivers in accidents involving serious injury is not available.
