15mph - Class RA1 - Temporary - Safety Signs by Caledonia Signs

Commonly used in temporary traffic management zones such as roadworks, construction sites, event areas, private estates, and depot yards. The 15 mph limit balances the need for safety with the practicalities of traffic flow, allowing vehicles to move cautiously but without causing undue delay. It is often applied where pedestrian activity is present or where vehicle movements are complex and require drivers to be alert and responsive.

Important for maintaining safety in areas where slower speeds (like 5 or 10 mph) aren’t necessary but where higher speeds could still pose a hazard. It helps prevent accidents by moderating vehicle speeds and encouraging driver attentiveness in dynamic, temporary situations. Legally enforceable where it is placed, typically in environments requiring controlled vehicle speeds to enhance safety.

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.
