HC Deb 16 December 1981 vol 15 c155W
Dr. Roger Thomas

asked the Secretary of State for Transport if he will publish in the Official Report how many lorries jack-knifed in fatal and serious accidents in each year between 1969 and 1981; and if he will give the corresponding figures or each country in Europe.

Mr. Kenneth Clarke

The number of heavy goods vehicles which jack-knifed in injury accidents by severity of accident, in Great Britain in 1979 to 1980, were as follows:

Fatal Serious Slight All severities
1979 45 169 351 565
1980 38 165 267 470

Information on jack-knifing for years prior to 1979 and comparable information for other countries could be obtained only at disproportionate cost.
