§ Mr. Knoxasked the Secretary of State for the Environment if he is satisfied with the use of fog-warning lights on motorways; and if he will make a statement.
§ Mr. CarlisleI have been asked to reply.
Chief officers of police make the most effective arrangements possible, but some signs that give warning of fog or other hazards on motorways have to be switched on and off individually, which causes delay. These signs are being progressively superseded by remote-controlled signs.
