HC Deb 06 April 1965 vol 710 c52W
58. Sir N. Cooper-Key

asked the Minister of Transport whether he is aware that at certain times of the year mist on the rear windows of private cars renders centre interior mirrors useless; and whether he will make regulations that all vehicles shall be fitted with mirrors on mudguards.

Mr. Tom Fraser

The fitting of external mirrors is already compulsory for goods vehicles, heavy passenger vehicles and dual purpose vehicles. Cars must have a mirror providing rear vision—though the type is not specified—and there is a Regulation requiring all glass to be kept so that vision is not obscured when driving.

Provided the advice in Rules 16, 31 and 82 of the Highway Code is followed, I think that safety can be preserved by a driver whose car has either type of mirror, and I have not seen evidence to suggest that a further Regulation would help.
