Road Works - Class RA1 - Safety Signs by Caledonia Signs

Warn road users of temporary works or maintenance activities on the road ahead. Its primary purpose is to enhance safety by alerting drivers, cyclists, and pedestrians to potential hazards caused by road works. By providing advance notice, it allows road users to slow down, stay alert, and navigate the area safely, reducing the risk of accidents or collisions.

The RA1 classification refers to a specific standard of road works signage, typically used for short-term or minor works where temporary hazards exist but traffic flow is not significantly disrupted. These signs are designed to be highly visible, using reflective materials and standardized symbols to convey the warning clearly. This ensures consistency across different locations, making it easier for drivers to recognise and respond appropriately.

Commonly placed at the start of a work zone, on approach roads, or at intersections leading to the affected area. Placement is critical: they must be positioned far enough in advance to give drivers time to react, but close enough to clearly indicate the location of the works. Proper placement also helps protect both the road workers and the public by reducing the chance of accidents within the work zone.

In addition to safety, these signs serve a regulatory function by helping road authorities comply with legal requirements for temporary traffic management. They are essential for construction companies, utility workers, or maintenance crews conducting repairs, inspections, or other temporary operations on public roads. Using RA1 signs consistently ensures public safety, legal compliance, and smooth traffic flow around road works.

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.
