§ Sir Clive Bossom
asked the Minister of Transport (1) what results have been obtained from experiments with the amber warning lights on motorways; and how these compare with the results on the M.5 motorway;
(2) what plans are being made to produce a more permanent and satisfactory remote-controlled warning light system for motorways.
§ Mr. John Morris
The temporary amber flashing warning lights and the M5 warnings signs have both helped to reduce speeds at hazards on motorways. The M5 signs are more comprehensive than the temporary amber lights and can indicate three different messages—"Accident" "Skid risk" and "Fog", accompanied by "Slow". My right hon. Friend is considering the provision of a permanent signalling system for all motorways and will announce her decision as soon as she can.
