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

Warn drivers of temporary road conditions that make the surface slippery and hazardous, such as ice, snow, wet leaves, or freshly treated roads with salt or grit. The "Class RA1 " classification indicates that the sign meets specific safety and reflectivity standards for temporary traffic signs, ensuring it is highly visible to motorists, especially in low-light or adverse weather conditions.

This sign is typically placed on roads where temporary slippery conditions are expected or have been identified, such as after snowfall, during freesing temperatures, or when maintenance work involving de-icing or cleaning has been carried out. Common locations include rural roads, bridges, shaded areas, or steep inclines where slippery conditions are more likely to occur. The purpose is to alert drivers to reduce speed and exercise extra caution to prevent accidents and maintain road safety until the hazard is cleared.

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.
