Driving in a new country can be daunting, especially when the signs look different. The UK uses a logical system of shapes and colors to convey information. Here is a quick guide to help you navigate British roads safely.
The Shape Matters
The most important thing to remember is the shape of the sign. It tells you the type of instruction.
Circles
Orders. You MUST follow them. Red circles tell you what you must NOT do (e.g., speed limits). Blue circles tell you what you MUST do (e.g., turn left).
Triangles
Warnings. These warn you of hazards ahead, like sharp bends, roadworks, or animals crossing.
Rectangles
Information. These give directions. Blue for motorways, green for primary routes, white for local roads.
Common Signs Explained
National Speed Limit
A white circle with a black diagonal stripe. This means the "National Speed Limit" applies. See our speed limits guide for details.
- 60 mph on single carriageways
- 70 mph on dual carriageways and motorways
Give Way
An upside-down red triangle. You must give way to traffic on the major road ahead. You don't necessarily have to stop if the way is clear.
Brown Tourist Signs
Rectangular brown signs with white text and symbols point to tourist attractions, such as castles, zoos, or museums.
Motorway Signals
On smart motorways, you will see electronic signs overhead.
- Number in a red circle: Mandatory speed limit. You must obey this.
- Red X: Lane closed. You MUST NOT drive in this lane. It is dangerous and illegal.
Tip for Visitors
Distances on UK road signs are in miles and yards, not kilometers. Speed limits are in miles per hour (mph).
