HC Deb 15 December 1980 vol 996 c70W
Mr. Alton

asked the Minister of Transport how many road accidents occurred between 2 November and 16 November which were attributable to ice and snow.

Mr. Kenneth Clarke

Causes of accidents are not identified in reports to my Department. In 1979, 7 per cent. of injury accident reports indicate the presence of ice or snow. Half the vehicles involved skidded. A particular recent period could not be analysed without disproportionate cost.
