Grass Cutting Supplementary Plate - Class RA1 - Safety Signs by Caledonia Signs

A Grass Cutting Supplementary Plate – Class RA1 is a temporary road sign used to warn drivers that grass cutting operations are taking place near the road. It serves as an additional plate beneath a main warning sign, such as “Road Works” or “Men at Work,” and provides specific context for the maintenance activity. The purpose of this supplementary plate is to enhance road safety by informing drivers of the nature of the work being carried out, so they can adjust their speed and driving accordingly.

The sign is commonly used on rural and suburban roads where grass verges, embankments, or central reservations require regular maintenance. These areas often have higher speed limits, making it important to give drivers early warning of potential hazards. By clearly indicating that grass cutting is in progress, the supplementary plate reduces the risk of sudden braking or collisions with maintenance vehicles.

It plays a crucial role in protecting roadside workers. When drivers know what to expect, they are more likely to reduce speed and give more space to workers operating near the carriageway. This increased awareness improves safety for both road users and maintenance crews, especially in areas with limited visibility or where vehicles may enter and exit the work zone frequently.

In practice, the Grass Cutting Supplementary Plate is used during the active period of maintenance, often placed temporarily and removed once the operation is complete. It supports other temporary traffic management measures, such as cones, temporary speed limits, or flashing lights, helping ensure smooth and safe traffic flow around the work zone.

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.
