Diversion - Arrow Left - Class RA1 - Temporary - Safety Signs by Caledonia Signs

A “Diversion – Arrow Left” sign is a temporary road sign used to guide drivers onto an alternative route when the usual road ahead is closed or inaccessible. It features the word “Diversion” with a left-pointing arrow, instructing traffic to turn left to follow a planned detour. This sign is essential for maintaining safe and efficient vehicle movement during road closures, construction, or emergencies.

This sign is typically used on public roads, near junctions, roundabouts, or intersections, where a left turn is required to begin or continue along a designated diversion route. It's particularly important in areas where road users might otherwise be uncertain about which direction to take when encountering a road closure or restriction.

Placement of the sign is crucial—it should be installed at key turning points, such as before a junction where drivers must turn left, or at intervals along the diversion route to reassure motorists they are still on the correct path. It often works in conjunction with other signs like “Road Ahead Closed”, “Diversion Ahead”, and other directional arrows to form a clear, continuous diversion route.

In practice, the “Diversion – Arrow Left” sign is part of a wider temporary traffic management strategy. It helps avoid driver confusion, reduces congestion near closed roads, and ensures continued access to key destinations. By giving clear, early instructions, it improves road safety and helps drivers navigate unfamiliar or changed routes with confidence.

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.
