HC Deb 10 February 1986 vol 91 cc317-8W
Mr. Macfarlane

asked the Secretary of State for the Home Department how precisely police forces record the location of accidents involving the deaths of motorists on motorways; and if he will make a statement.

Mr. Giles Shaw

I understand that the police record the location of cars involved in accidents on motorways by reference to the numbered marker posts situated at 100 m intervals along each carriageway. Photographs are also normally taken in fatal accident cases.
