What are regulatory signs?
Regulatory signs are part of the UK road and traffic sign system used to give drivers and riders clear
instructions about what is mandatory, what is prohibited and who has priority on the road. They help you
understand where you must not enter, which direction you must follow, and what speed limits apply, so you can plan
your journey safely and confidently.
You'll usually see:
- Prohibitive signs (often red circles) showing what you must not do, such as 'No entry' or 'No
overtaking'.
- Mandatory signs (often blue circles) telling you what you must do, such as 'Turn left' or
'Keep right'.
- Priority and speed limit signs giving instructions about who has priority at junctions and
what maximum speed you must not exceed.
Understanding these regulatory signs is essential if you regularly drive on unfamiliar roads, in busy towns and
cities or on rural routes - and they can all appear in your DVSA driving theory test and hazard perception
test.
