One Way Traffic - Class RA1 - Safety Signs by Caledonia Signs

This temporary sign is used to clearly indicate that traffic must proceed in a single direction only, helping to manage vehicle flow safely and efficiently during temporary road changes. This sign is vital for preventing confusion and potential collisions when normal traffic patterns are altered.

Typically, it is deployed in temporary traffic management situations such as roadworks, events, detours, or lane closures where two-way traffic is restricted or redirected. It ensures that drivers are aware of the enforced one-way flow, reducing the risk of head-on collisions and improving traffic safety in altered or constrained environments.

Using this temporary sign supports safe and orderly movement through work sites or event areas, protects workers and road users, and aids in efficient traffic management when permanent signs cannot be used or when traffic patterns must change temporarily.

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.
