HC Deb 16 November 1967 vol 754 c172W
58. Mr. Hooley

asked the Secretary of State for the Home Department if he will obtain a report from the chief constable as to the action taken to close the Pinxton to Barlborough stretch of the M1 in fog until fog warning lights are installed and in working order.

Mr. Roy Jenkins

The chief constable informs me that fog occurred only once before the installation of hazard warning signals began on that stretch of the motorway. He decided not to close it on that occasion because, with fog warning signals on all approach roads and fog warning signs on the motorway to the south, traffic was safer on the motorway than if diverted to roads with two-way traffic.
