HC Deb 25 February 1992 vol 204 c482W
Mr. Corbett

To ask the Secretary of State for Transport what studies he has made of the impact of lighting on motorways on the incidence of driver/ passenger fatalities and accidents; and with what results.

Mr. Chope

The results of a study undertaken by the Transport and Road Research Laboratory were published in 1987. The study concluded that there does not appear to be any evidence to support an increase in the Department's current assumption of a 30 per cent. reduction in night-time accidents, but the range of uncertainty remains high.
