5mph - Class RA1 - Temporary - Safety Signs by Caledonia Signs

A regulatory speed limit sign used to restrict vehicle speed to 5 miles per hour in specific temporary / private conditions. This sign is typically used in environments where extreme caution is required due to close proximity to workers, pedestrians, or hazards. Typically deployed in temporary traffic management situations, such as roadworks, depot areas, site entrances, event spaces, or car parks where very low-speed driving is essential for safety.

This 5 mph limit is not usually applied to public roads but is critical in non-public or restricted-access areas, where slow and cautious driving is essential. Without such signage, drivers might enter high-risk areas at unsafe speeds, increasing the potential for accidents and / or fatalities. This sign plays a vital role in protecting both workers and the public in temporary, high-risk environments.

Traffic sign design to Chapter 8, DfT and TSRGD guidelines - Key components of traffic management and road safety regulations in the UK. Each plays a distinct but interrelated role in how road signs, markings, and temporary traffic control measures are designed, installed, and maintained.

Supplied complete with channeling for post mounting.

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.
