HC Deb 05 July 1978 vol 953 c195W
24. Sir J. Langford-Holt

asked the Secretary of State for Transport how many accidents and how many deaths were caused in the last 12 months by jackknifing of articulated vehicles; and what discussions he has had with manufacturers of heavy goods vehicles on the subject.


In 1977, 380 articulated heavy goods vehicles were reported to have jack-knifed in accidents resulting in injuries; deaths occurred in 21 of these cases. It is not possible to distinguish between cases in which jack-knifing led to the accident and cases in which jackknifing resulted from it. Detailed discussions have been taking place with manufacturers on measures to apply new braking standards which will reduce the risk of jack-knifing.
