HC Deb 26 April 1971 vol 816 c36W
Mr. Redmond

asked the Secretary of State for the Environment whether he is aware that some highway authorities are already putting up warning notices giving distances of hazards ahead in terms of metres rather than yards; and what guidance is at present given by him to highway authorities in connection with signs in metricated language.

Mr. Eldon Griffiths

Warning signs on roads must show distances in miles or yards. I will gladly look into any case where signs appear to have been erected in contravention of the Regulations.
