§ 41. Mr. Francis Noel-Baker
asked the Minister of Transport, if he will take steps to mitigate the consequences of 139W sudden multiple pile-up accidents on the M4 and other motorways, by the installation of modern signalling systems based on those in use on railways, or by the introduction and enforcement of headway regulations.
§ Mr. Swingler
Yes. Such systems should be installed on all motorways by the mid-1970s. The first came into operation at the Severn Bridge last Friday.
Headway regulations could not be made effective. The Highways Code already advises drives not to drive too close to the vehicle ahead.
