 Reflectorised signs should be so mounted that they can be seen in dipped headlights (paragraph 272).

Specular reflection should be avoided by turning signs 5° away from oncoming traffic on straight roads.

Waiting restriction signs should be mounted at right angles to the road and on top of their posts. But supplementary plates should be set parallel to the carriageway (paragraph 273).

No entry signs should be set so as to face drivers attempting to enter the street (paragraph 274).

The smaller signs should be fixed when possible to existing posts or walls, but should remain conspicuous. Round posts should be used. If enlargement of the post is necessary to contain equipment it should be at the base. The post should not show above the sign (paragraph 275).

Between a sign and the plate beneath it there should be a space sufficient to avoid impairing the outline of the sign (paragraph 276).

Overhead mounting may be necessary in heavily trafficked urban streets when roadside signs and carriageway markings are liable to be obscured (paragraph 277).

No entry signs should continue to be placed on both sides of the street.

No right/left turn signs attached to primary traffic signals should be duplicated on the signals, if any, on central refuges (paragraph 278).

Advance directions signs should be placed on the central reservation, provided it is wide enough, of all high-speed dual-carriageway roads, as well as on the nearside (paragraph 279).

On the approaches to grade separated junctions on roads built to near motorway standards there should be two map type advance direction signs, one half a mile before the junction and the other at the beginning of the deceleration lane. On the first the forward destination should be omitted and the distance to the junction added.

Direction signs at roundabouts should be so located as not to prevent drivers from seeing traffic coming from the right (paragraph 280).

Ministers should control more closely the three-dimensional design of signs. Manufacturers should employ experienced designers (paragraph 281).
