This red-bordered triangle shows a bicycle and warns that a cycle route joins or crosses the road ahead. It is used where a traffic-free path meets the carriageway.
Riders may emerge at speed and at an unusual angle, which is why the warning exists.
What this sign means
Cyclists will be joining or crossing your road, often from a path that is set back from the carriageway and partly hidden.
A plate below may show the distance to the crossing point.
What to do when you see it
Slow down and search the verges and path entrances.
- Reduce speed on the approach.
- Look for riders behind hedges, fences and parked vehicles.
- Be prepared to give way at a marked cycle crossing.
- Leave plenty of room when passing riders who have joined.
