The No U-Turn Sign – Diagram 614 is a mandatory UK traffic sign used to prohibit drivers from performing a U-turn on a specific stretch of road. Essential for safety at junctions, dual carriageways, and high-speed roads, it ensures controlled traffic flow and reduces risk of head-on collisions or traffic disruption.
Compliant with TSRGD Diagram 614, BS EN 12899-1, and Chapter 3 of the Traffic Signs Manual, this red-bordered circular sign features a bold black U-turn arrow crossed out by a red diagonal bar—signifying a legal prohibition on reversing direction.
Manufactured in the UK using RA2 or R3B reflective sheeting, this sign is available in all standard UK circular sizes from 300mm to 1500mm. Material options include aluminium, composite, or self-adhesive vinyl, with mounting choices like channel rails, plate-only, or adhesive fixings.
Technical ReviewDiagram 614 clearly prohibits U-turns, especially in high-risk locations such as busy junctions, dual carriageways, or where forward-only movement is essential. Its bold, universally recognised graphic provides quick, unambiguous instruction to all drivers.
