A junction on a bend presents a double hazard: reduced cornering visibility combined with vehicles emerging from or turning into a side road.
This warning sign prepares drivers to anticipate emerging traffic or vehicles slowing ahead to make a turn on a curve.
What this sign means
It indicates that a side road intersects the main carriage pathway while the road is curving.
- Red triangle warning symbol
- Black junction outline situated across a curve symbol
- Alerts to restricted visibility at intersecting roads
What to do when you see it
Slow down in good time and check rear-view mirrors. Be prepared for slow vehicles pulling out unexpectedly from the side road.
- Scan the side junction as early as possible
- Be ready to stop if emerging traffic blocks the lane
- Avoid overtaking near or on the junction area
How this sign is tested
The DVSA theory exam tests your hazard perception skills and understanding of priority rules near hidden side roads.
Common mistakes
Assuming vehicles on the side road can see you clearly; blind spots caused by roadside hedges or trees are common.

Practise road sign questionsFrequently asked questions
Who has priority at a junction on a bend?
Traffic remaining on the main road has priority unless signs or road markings state otherwise.
Why is overtaking here particularly dangerous?
Overtaking vehicles block views of emerging cars and prevent safe evasive manoeuvres.
What supplementary signs might accompany this sign?
Plates showing distance to junction or specific side-road layout diagrams are frequently used.
