Traffic signs explained
Knowing your signs is essential for your theory test and for safe driving. Here’s the quick version.
UK traffic signs follow a simple shape code: circular signs give orders, triangular signs warn of hazards, and rectangular signs inform or give directions. Learning this pattern makes the theory test far easier and keeps you safe on the road.
Signs giving orders
Circular signs give orders. A red ring or circle means something is prohibited; blue circles usually give a positive (mandatory) instruction.
- Stop and give way
- No entry for vehicles
- No overtaking
- Maximum speed limit
- Mini-roundabout - give way
- Turn left ahead
Warning signs
Triangular signs warn you of hazards ahead so you can react in good time.
- Crossroads
- Roundabout ahead
- Junction on a bend
- Slippery road
- Pedestrian crossing
- Risk of falling rocks
Direction & information signs
Rectangular signs give information or directions - blue on motorways, green on primary routes and white on minor roads.
- Motorway route
- Primary route
- Tourist destination
- Parking
- Hospital
- Diversion route
