HC Deb 10 December 1980 vol 995 c374W
16. Mr. Penhaligon

asked the Minister of Transport what is the latest annual figure for road deaths and casualties, respectively, attributable to drunken driving; and whether he will make a statement.

Mr. Kenneth Clarke

Provisional figures for 1979 indicate that 1 in 3 of drivers killed in road accidents had blood alcohol levels over the legal limit. In about 1 in 10 of all road accidents, including damage-only accidents, alcohol is considered to be a significant contributory cause.
