§ Mr. Pawseyasked the Secretary of State for Transport what is the average number of accidents per motorway mile in each of the last three years for which figures are available where the top surface is (a) tarmacadam and (b) concrete: (i) in all conditions and (ii) in wet conditions; and if he will make a statement.
§ Mrs. Chalker[pursuant to her reply, 24 November 1983, c. 231]: I am sorry to have to tell my hon. Friend 323W that information as to road top surface is not included on police accident reports supplied to my Department. Collation of accident reports with other records of road surface would be disproportionately costly and cannot be authorised.
