Mr. Marlow

asked the Secretary of State for Transport what are the night accident record criteria used in assessment of decisions to erect street lights on country roads such as the A45.

Mr. Kenneth Clarke

Night-time personal injury accidents over a period of at least three years for the length of road being considered for the erection of street lighting are averaged to an annual figure.
