asked the Secretary of State for the Environment if he will provide the latest figures for deaths and other accidents on roads in the United Kingdom; and whether it is still the case that some 35 per cent. of these casualties occur during darkness when traffic flow is estimated at approximately 30 per cent. of the total.
In 1973, 7,400 people were killed and 346,000 injured. About 36 per cent. of the casualties were incurred during hours of darkness. Separate estimates of traffic flows in daylight and darkness are not available.
