Keep Left - Class RA1 - TSRGD Diagram: 610 - Keep Left / Keep Right Road Signs

This essential regulatory road sign is used to direct traffic safely around physical obstructions. Its main purpose is to provide clear and mandatory guidance to drivers, instructing them to pass on the left-hand side of a hazard or obstruction. By clearly indicating the correct side to pass, the sign helps prevent confusion and potential collisions.

This sign is vital for maintaining road safety and orderly traffic movement. Positioned strategically, it ensures that drivers are aware of changes in road layout or unexpected barriers. Since it is a regulatory sign, compliance is legally required, and failure to follow the instruction could result in penalties or, more seriously, accidents. The simplicity and clarity of the message , a white arrow on a blue circular background , make it easily recognisable.

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.

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.
