asked Her Majesty's Government:How many (a) heavy goods vehicles; (b) buses and coaches; and (c) cars were caught speeding on the motorways between 1982 and 1987.

No reliable information is available for specific types of vehicle. The available information relates to total findings of guilt in magistrates' courts for exceeding 70 mph limits on motorways. It is published annually in Offences relating to motor vehicles, England and Wales, Supplementary Table (Table 5 of the issue for 1986). The report of a national speed survey, which was conducted in 1987, gives results for different vehicle types and has recently been published by the Department of Transport in Statistical Bulletin number (88)30. Copies of both publications are in the Library.
