Signals, road signs and markings

Road signs, markings and signals are there to help you drive safely and to keep traffic flowing. It’s vital that you understand what the different signals, signs and markings mean and what to do when you see them.

  • Circular signs tell you what you must or must not do.
  • Warning signs are red and usually triangular.
  • Road markings give information, orders or warnings.

Look at The Official Highway Code and Know Your Traffic Signs for details of all the signs and markings.

The speed limit is shown on a circular sign. Where no speed limit is shown, the national speed limits (GOV.UK) apply. These vary depending on the type of road on which you’re driving.

Signals can be used by police officers, crossing patrols and other people who are authorised to control traffic, such as DVSA and Highways England traffic officers. Make sure you know what these signals mean and what to do when you see them. The Highway Code (GOV.UK) contains a guide to these signals.
