No Right Turn - Class RA1 - TSRGD Diagram: 612 - No Right Turn Road Signs

Commonly used during roadworks, diversions, or temporary route adjustments, where allowing a right turn could endanger drivers, disrupt traffic flow, or interfere with site operations. It ensures that vehicles follow safer, designated routes and helps prevent collisions with oncoming traffic or conflict with temporary lane setups and priority systems.

This No Right Turn Class RA1 Temporary sign is a UK regulatory traffic sign used to indicate that drivers are prohibited from turning right at a specific location under temporary / private traffic conditions. The sign features a black right-turn arrow crossed by a red diagonal bar, set within a white circular background with a red border, clearly communicating that right turns are not allowed. As a Class RA1 sign, it is legally enforceable and must be obeyed when displayed.

Restrictions are especially important in areas with altered traffic patterns, such as junctions that have been reconfigured for temporary use or where visibility and space are limited. By preventing right turns, the sign helps reduce delays, improve driver decision-making, and minimises the risk of accidents in high-risk or congested locations. Essential for maintaining safe and efficient traffic movement in line with UK road safety guidance, including Chapter 8 of the Traffic Signs Manual.

Traffic sign design to Chapter 8, DfT and TSRGD guidelines - Key components of traffic management and road safety regulations in the UK. Each plays a distinct but interrelated role in how road signs, markings, and temporary traffic control measures are designed, installed, and maintained.

Supplied complete with channeling for post mounting.

Materials Explained

Any product outside of our standard choice of material/size range starts with a 5. This may include items such as rolls of tape, sign frames, floor graphics or banners. Below you can find a more detailed description of the miscellaneous material options available for this sign design.

Class RA1: Manufactured from 3mm aluminium composite with an engineering grade retroreflective sheeting to ensure visibility during day and night. This reflective layer helps headlights bounce light back to drivers, making the sign readable in low-light conditions and offers approximately a 7 years lifespan. Aluminium composite is a lightweight, durable material which holds no scrappage value - reducing the potential for theft. It is weather and rust resistant - overall, RA1 signs are designed to be durable, weatherproof, and highly visible to ensure the safety of road users around temporary worksites.
