Flood - Class RA1 - Safety Signs by Caledonia Signs

This temporary warning sign designed to alert drivers to areas prone to flooding or where flooding is currently affecting the road. The “Class RA1” designation means the sign meets strict reflectivity and visibility standards, ensuring it can be clearly seen in poor weather conditions, low light, or at night. This high visibility is crucial for safety because flooding can create dangerous driving conditions such as reduced traction, hidden hazards, or deep water that can stall or sweep vehicles away.

These signs are typically used in areas known to be flood-prone, such as low-lying roads near rivers, coastal areas, or regions with poor drainage systems. They are often deployed by local authorities or emergency services when heavy rains or storms cause temporary flooding, warning drivers in advance so they can slow down, take alternative routes, or avoid the area altogether. The sign helps prevent accidents caused by unexpected water on the road and protects both motorists and emergency responders.

Using a Flood – Class RA1 sign is important because flooding can cause sudden and severe hazards, including hydroplaning, loss of vehicle control, and damage to vehicles. The sign acts as a clear, visible warning that conditions are unsafe, encouraging drivers to take precautionary measures. It also supports traffic management efforts by reducing congestion and directing traffic away from dangerous flood zones.

In summary, the Flood – Class RA1 sign plays a vital role in road safety during adverse weather events. It is placed in flood-affected or flood-prone locations to alert drivers to the risk and promote cautious driving. Its high reflectivity ensures visibility in challenging conditions, helping to minimise accidents, protect lives, and support emergency response efforts during floods.

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.
