§ Mr. Eldon Griffithsasked the Secretary of State for Transport if he will review the fog code with a view to determining which items in it could with advantage be made mandatory; if he considers that the present advisory speed limits in fog should be enforceable at law and if so what additional powers would be required by the police to enable them to bring prosecutions; and what steps he is taking to provide flashing speed limit signs on all motorways and dual carriageways in fog-prone areas which at present do not have them.

§ Mr. HoramThe use of headlights in poor daytime visibility is already mandatory. The other points in the code are reminders or exhortations which could not easily be enforced, but drivers who behave recklessly or dangerously are open to prosecution. To make advisory speed limits enforceable would necessarily mean that the system would be less flexible. At present 580 miles of motorway are equipped to display advisory speed limits and plans are in train for 380 more miles, but my right hon. Friend has no plans to extend the motorway signalling system to dual carriageway roads.
