HC Deb 06 March 1963 vol 673 c47W
75. Mr. Hocking

asked the Minister of Transport what instructions are given to contractors carrying out maintenance work on motorways with regard to the placing of warning lights during the hours of darkness.

Mr. Hay

Contractors are required to comply with the traffic safety code for works on motorways. This requires that all warning signs shall be reflective, so that they can be clearly seen in vehicle headlights. The code does not call for the use of warning lights although some contractors use them to supplement the signs.
