The 'No Right Turn' sign features a black arrow pointing right with a red prohibition slash across it, set inside a red ring.
It is placed prior to junctions, one-way systems, or private entrances where right-turning traffic would block major flows or cross dangerous oncoming traffic lanes.
What this sign means
Drivers must not turn right at the junction or location where the sign is situated.
The restriction applies equally to private entrances, side roads, and multi-lane intersections.
- Rightward arrow with diagonal red prohibition bar.
- Prevents cross-traffic obstruction and head-on conflict.
- Mandatory compliance for all vehicle categories.
What to do when you see it
Plan your route to proceed straight ahead or turn left as directed by lane signs.
To reach a destination on your right, proceed past the junction and use a subsequent roundabout or side street block to turn around.
How this sign is tested
Theory exams present multiple-choice junction diagrams asking which manoeuvres are legal when approaching this sign.
Questions test whether you understand that turning right remains illegal even if the road appears empty.
Common mistakes
Assuming a right turn is permitted when no oncoming cars are visible is a critical mistake.
Drivers sometimes confuse this sign with 'Ahead Only' or fail to spot it when positioned alongside high-level traffic light signals.

Practise road sign questionsFrequently asked questions
Can I turn right if traffic signals show a green ball light?
No, prohibitory road signs override green directional light indications unless a specific green arrow permits the move.
What should I do if I accidentally enter a No Right Turn junction?
Proceed straight or left safely; never complete an illegal right turn.
Is 'No Right Turn' always placed on the left side of the road?
It is often duplicated on traffic light posts or central islands for maximum visibility.
