HL Deb 12 July 1999 vol 604 c12WA
The Marquess of Ailesbury

asked Her Majesty's Government:

Whether statistics show that the westbound elevated section of the M.4 was a dangerous stretch of road when it had a 50 mph limit. [HL3217]

The Parliamentary Under-Secretary of State, Department of the Environment, Transport and the Regions (Lord Whitty)

The total number of accidents on the M.4 elevated westbound in the five-year period January 1994 to December 1998 was 70, of which 23 were speed related. This total is 55 per cent. higher than the average personal injury accident rate for dual 2 lane motorways with a 50 mph limit.
