Using this temporary speed limit sign helps manage traffic flow effectively in high-risk areas, reducing the chance of accidents by clearly communicating the need to slow down.

In summary, the 20mph - Class RA1 - Temporary sign is an important safety tool for controlling vehicle speeds in temporary zones. It enhances protection for workers and road users by clearly indicating when slower speeds are required.

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.
