Traffic signs play a vital role in directing, informing and

controlling road users' behaviour in an effort to make

the roads as safe as possible for everyone . This makes

a knowledge of traffic signs essential.

Why know traffic signals?

There are three basic types of traffic sign; signs that give orders, signs that

warn and signs that give information. Each type has a different shape.

The signing system

A further guide to the function of a sign is its colour.

The signing system

Blue circles generally give a mandatory instruction , such as

"turn left", or indicate a route available only to particular

classes of traffic, e.g. buses and cycles only

Red rings or circles tell you what you must not do, e.g. you

must not exceed 30 mph, no vehicles over the height shown

may proceed

The signing system

Green rectangles are used for direction signs on primary

routes

White rectangles are used for direction signs on non-primary

routes, or for plates used in combination with warning and

regulatory signs.

Blue rectangles are used for information signs except on

motorways where blue is used for direction signs.
