Temporary Road Surface - Class RA1 - Safety Signs by Caledonia Signs

Warn drivers that the road ahead has a surface that is not permanent, such as freshly laid asphalt, gravel, or other temporary materials. This advance notice helps alert drivers to adjust their speed and driving style to suit potentially uneven, slippery, or loose road conditions.

One key reason for using this sign is to enhance safety. Temporary road surfaces can affect vehicle handling, braking distances, and traction. By warning drivers in advance, the sign encourages caution, reducing the risk of accidents caused by sudden changes in road grip or unexpected bumps.

The sign also helps maintain traffic flow by preventing abrupt braking or swerving when drivers suddenly encounter unfamiliar road conditions. Drivers who are prepared for a temporary surface are more likely to navigate the area smoothly, reducing congestion and potential hazards.

Inform drivers of ongoing maintenance or construction work affecting the road, promoting awareness and responsible driving. Proper signage is essential for protecting both drivers and workers in affected zones.

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.
