Plastic supplementary sign plates are a crucial extension to standard roadway sign systems. They provide additional information to both drivers and pedestrians, supporting main warning signs by giving details such as distance to works, hazard end points, or nature of activity. These quick signs plates are pre-drilled for 300mm or 450mm centres to fit standard quick fit sign frames.
Applications include guiding traffic through hedge cutting areas, alerting road users about single-lane restrictions, and marking distances such as 100 yards or 1 mile ahead. By enhancing the clarity of traffic road signs, they help reduce confusion and maintain a safe, efficient environment for public access and contractor operations.
- Flexible attachment options - Available with 300mm or 450mm drilling centres to fit standard quick signs.
- Site communication tool - Conveys details like distance or site activity below the primary roadway sign.
- Reusable traffic signage - Tough plastic build suitable for frequent site redeployments.
- Pedestrian and driver guidance - Minimises confusion during temporary roadworks or access changes.
- Compatible with HERMEQ frames - Designed to integrate seamlessly into your existing signage setup.
These supplementary plates form an essential component in managing road and site safety. They support standard quick signs by displaying concise follow-up instructions or situational details. Whether you're alerting drivers that “Single File Traffic” lies ahead or stating “100 Yards” until disruption, these additions boost clarity and prevent misinterpretation.
Often used by traffic control teams, civil engineering contractors and infrastructure developers, they allow you to scale your traffic road signs intelligently, adapting to layout shifts and environmental variables. The plastic build means they're easy to handle, install, and switch out as needed, without compromising on visual impact.
HERMEQ stock a wide-range of Traffic Signs, Traffic Management Equipment, Quick Fit Signs & Road Plates conforming to all required safety specifications and regulations.

Supplementary roadway signs like these plates are indispensable for site-specific messaging. Their purpose is to inform road users and pedestrians about additional details not covered by the main signage. When mounted correctly below primary signs, they communicate information such as the nature of the works, distance to disruption, or end of controlled areas.
Industries that frequently utilise these signs include highway maintenance teams, local councils, utility providers, and private contractors working on civil projects. Their value lies in both the flexibility and precision they offer. Instead of cluttering a single sign with too much information, these supplementary units allow the display to remain clear and modular.
Common messages include “End” (marking the termination of roadworks), “Single File Traffic” (for narrowed routes), and distance-based signs like “100 Yards” to give early warnings. This layered communication ensures users have enough time to understand what lies ahead and react safely. This is particularly crucial in urban areas, high-speed roads, or during night works where visibility and decision-making time are limited.
The plastic used is strong and lightweight, making these signs easy to transport and fix. They are drilled either at 300mm or 450mm centres — dimensions compatible with HERMEQ’s quick sign frames and many other standard frame systems in the industry.
Because of the repeat use design, these supplementary plates are cost-effective over long-term projects or multi-phase rollouts. They are a low-cost way to enhance safety and communication at scale. Teams often rotate them across different worksites, changing only the top primary sign as needed.
When setting up a complete system, these signs are typically used alongside Traffic Management Equipment, especially where dynamic guidance is required. Contractors also combine them with cones, base plates and primary quick signs to create a full traffic redirection plan that meets both legal and safety obligations.
What is a supplementary roadway sign plate?
It's a plastic plate that sits below the main sign on a quick fit frame to provide extra traffic information.
What messages do these signs usually display?
Common messages include distance warnings (“100 Yards”, “1 Mile”), activity alerts (“Grass Cutting”), and instructions like “End” or “Single File Traffic”.
What sizes do they come in?
These plates are compatible with both 300mm and 450mm centre quick signs frames, covering most industry-standard setups.
Are these traffic road signs reusable?
Yes, they’re designed from durable plastic and suitable for ongoing redeployment across multiple worksites.
