HC Deb 30 November 1978 vol 959 c312W
Mr. Biggs-Davison

asked the Secretary of State for Transport what proportion of drivers and passengers involved in road accidents were and were not wearing seat belts.

Mr. Horam:

I regret that this information is not available nationally as accidents in which no personal injury occurs are not reported to our Department.

However, a recently published localised study of accidents in the area around the Transport and Road Research Laboratory—TRRL report LR 811—indicated that some 30 per cent. of front seat occupants of cars were wearing seat belts at the time of the accident.
