Know your traffic signs
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. Not just for new drivers or riders needing to pass their theory test, but for all road users, including experienced professional drivers
The Traffic Signs System
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.
A further guide to the function of a sign is its colour.
All triangular signs are red.
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.
Blue rectangles are used for information signs except on motorways where blue is used for direction signs
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
There are a few exceptions to the shape and colour rules, to give certain signs greater prominence.
Examples are the “STOP” and “GIVE WAY” signs
