No Left Turn - Class RA1 - TSRGD Diagram: 613 - No Left Turn Road Signs

This temporary sign is typically used in situations such as roadworks, temporary diversions, events, or emergency traffic management, where turning left could cause safety issues, congestion, or conflict with other traffic movements. It helps maintain smooth and safe traffic flow by directing drivers to alternative routes and preventing potentially dangerous or obstructive manoeuvres.

The No Left Turn instruction is essential when normal junction layouts or access points have been temporarily changed. It ensures that drivers do not mistakenly enter restricted or unsuitable routes, such as one-way systems, construction zones, or heavily congested areas. By directing traffic away from unsafe or non-operational paths, it contributes to safer and more efficient navigation through disrupted areas.

Incorporating the No Left Turn Class RA1 Temporary sign into a temporary traffic management plan supports compliance with UK road safety standards. It reinforces clear and lawful behaviour during temporary disruptions, reducing the risk of accidents and improving overall traffic coordination.

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.
