HC Deb 29 July 1976 vol 916 c332W
Mr. Knox

asked the Secretary of State for the Home Department how many convictions for driving offences on motorways there were per mile of motorway in 1960, 1965, 1970 and 1975.

Dr. Summerskill

Information is available only in relation to offences against the Motorway Regulations and not for other motoring offences committed by drivers while on motorways. It is as follows:

Number of convictions per mile
Year Excluding Speeding Including Speeding
1960 12.0
1965 11.5
1970 8.9 12.2
1975 9.0 18.8

Information about speeding offences on motorways is not available for 1960, and for 1965 could be obtained only at disproportionate cost.
