The Caution Raised Manhole Covers roadway sign alerts drivers to elevated manholes following resurfacing or excavation works. As a temporary traffic sign, it helps prevent damage to vehicles and ensures reduced speeds in affected zones. These traffic road signs are critical in maintaining safe, controlled conditions during ongoing maintenance or partial surfacing projects.

This Caution Raised Manhole Covers roadway sign plays a critical role in alerting drivers to uneven road surfaces, particularly where manhole access points have been temporarily elevated during maintenance or resurfacing operations. It provides clear and proactive hazard notification to protect both public road users and onsite personnel.
- Manufactured with Zintec plate and 3M reflective face for robust visibility in all weather and light conditions.
- Clearly communicates a potential road hazard, prompting reduced speeds and increased driver caution.
- Essential during pre-surfacing phases or post-access chamber works where manholes protrude above the road surface.
- Available framed or unframed, allowing flexibility across mobile worksites or static installations.
- Integrates with cones, barriers, and traffic road signs for full site traffic management.
Often deployed during interim stages of road surfacing, these signs are a preventive tool for contractors, councils, and utilities providers. They alert drivers to irregularities that may not be visible until close range and help ensure lower approach speeds across the affected zone.
The reflective face ensures the sign remains readable from a safe distance under headlights or low daylight. Typical deployments include waterworks, telecom access points, streetlight chamber works, and storm drain upgrades. When positioned correctly, they reduce the risk of tyre, suspension, or undercarriage damage for passing vehicles. They are compatible with traffic cones, road plates and traffic barriers.

The Caution Raised Manhole Covers sign serves as a vital safety component during temporary roadwork scenarios. Installed where manhole lids are intentionally left raised during intermediate phases of street resurfacing or underground access, the sign acts as an advanced hazard notification for motorists.
Manufactured from long-life Zintec steel and laminated with 3M reflective material, the sign maintains exceptional visibility in challenging UK weather. It meets standard UK signage sizing at 600mm and is designed for roadside placement at sufficient distances to allow speed adjustment. Commonly used in pre-surfacing road stages or utility network repairs, it provides visual awareness that reduces risk of vehicle damage and enhances public safety compliance.
- Hazard Management – Informs road users of exposed or elevated ironwork to avoid sudden impact.
- Installation Flexibility – Use with or without frame to suit temporary, rolling, or fixed sign locations.
- Surface Protection – Prevents damage to manhole collars, surfacing, and vehicle underbodies during transitional phases.
- Trusted Across Sectors – Deployed by utility firms, civil engineers, and highway maintenance crews.
- Visibility Assured – 3M reflective technology supports safe night-time navigation around live work zones.
These signs are critical on roads where ironworks may remain raised for days or weeks during sequencing of surfacing layers or staged infrastructure rollouts. With heightened visibility and a direct safety message, they deliver on compliance duties under Chapter 8 signage guidance.
They also form part of a full temporary traffic sign system where they may be installed alongside Works Access signs and Diversion signs to redirect flow while clearly outlining risks. For utility frameworks or reactive maintenance works, they offer a quick-deploy hazard notification that supports public confidence and duty-of-care fulfilment.
