HC Deb 10 February 1965 vol 706 c96W
72. Mr. Kelley

asked the Minister of Transport if he will issue specific instructions to drivers of vehicles on motorways as to what action they should take after an advance warning of fog has been given.

Mr. Tom Fraser

No. Fog warning signs advise drivers of fog on motorways. Drivers should then be ready to take the normal fog precautions already suggested in the pamphlet "Motorway Manners". Some may choose to leave the motorway before meeting the fog.
