End Supplementary Plate - Class RA1 - Temporary - Safety Signs by Caledonia Signs

An End Supplementary Plate – Temporary sign is used to indicate the conclusion of a temporary traffic restriction, hazard, or roadwork zone. Placed beneath a main sign, it clearly informs drivers that the specific condition or instruction previously in place—such as a speed restriction, roadworks, or diversion—has officially ended. This helps drivers return to normal driving behaviour with confidence.

This plate is typically used at the end of temporary traffic management zones, such as construction or maintenance sites, where earlier signs may have imposed caution, speed limits, or lane changes. It ensures there is no ambiguity about when those temporary rules are no longer in effect, reducing the risk of confusion or inconsistent driving behaviour after passing through a work zone.

You’ll often find the End plate on roads with temporary signage for roadworks, grass cutting, lane closures, or diversions, particularly on rural roads, A-roads, or dual carriageways. It can be attached to temporary sign frames, cones, or barriers and is used to complement main warning signs or regulatory instructions placed earlier along the route.

In practice, the End Supplementary Plate plays a key role in temporary traffic control, ensuring smooth transitions back to standard road conditions. It helps inform drivers when they can safely resume normal speeds, lane usage, or road behaviour, contributing to both road safety and clarity for all users.

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.
