Road Closed - Class RA1 - Safety Signs by Caledonia Signs

A “Road Closed” sign is used to clearly inform drivers and pedestrians that a particular road is completely closed to all traffic. This warning helps prevent vehicles and people from entering unsafe or inaccessible areas, such as during major roadworks, emergencies, or special events.

The sign should be installed at all entry points to the closed road, ensuring that anyone approaching from any direction is aware that access is restricted. It is often used in urban and rural areas where road closures are necessary for construction, repairs, or safety reasons.

Using this sign enhances safety by preventing unauthorised access, reducing the risk of accidents or delays caused by blocked or hazardous roadways. It also helps manage traffic by directing drivers to use alternative routes.

Overall, the “Road Closed” sign is a vital part of traffic management and public safety, clearly communicating that the road ahead is not passable and ensuring that all road users comply with the closure.

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.
