Temporary Road Signs: A Practical Guide for Safer Roads

Temporary Road Signs: A Practical Guide

Temporary road signs help drivers, cyclists and pedestrians navigate changing conditions safely. They are commonly used during roadworks, events, emergencies and other situations where the usual road layout or traffic conditions have changed.

Clear, well-positioned signs give road users time to respond to hazards, follow diversions and understand what is expected of them. Choosing and using the right signs is therefore an important part of effective traffic management.

What are temporary road signs?

Temporary road signs are signs put in place for a limited period to communicate information or instructions. They may warn of hazards, impose temporary restrictions, direct traffic along an alternative route or guide people around a work area.

Unlike permanent signs, temporary signs are intended to reflect changing conditions. They should be suitable for the location and remain relevant, visible and legible for as long as they are needed. Once the work or event has ended, signs should be removed promptly so they do not confuse road users.

Common types of temporary road signs

The signs required will depend on the activity and the risks involved. Common examples include:

• Roadworks signs to warn of work ahead, uneven surfaces, loose material or workers in the road.
• Temporary speed-limit signs where a lower speed is required for safety.
• Road-closure and diversion signs to direct road users away from a closed route.
• Lane-closure and lane-diversion signs to show how traffic should pass an obstruction.
• Temporary traffic signals to manage traffic through a restricted section of road.
• Event signs to provide directions or warn of temporary access restrictions and increased pedestrian activity.
• Pedestrian and cycle-route signs to guide people safely around works or other obstructions.

Why are temporary signs important?

Unexpected changes can leave road users unsure where to go or what hazards lie ahead. Temporary signs help reduce that uncertainty by providing timely, consistent instructions. They can also help protect road workers and event staff, maintain access for residents and businesses, and reduce the risk of collisions or congestion.

Signs work best as part of a carefully planned traffic-management arrangement. Depending on the circumstances, this may also involve cones, barriers, temporary signals, road markings or a clearly managed diversion route.

Planning and positioning signs

Before temporary signs are installed, the site and the needs of its road users should be assessed. Consider the speed and volume of traffic, sightlines, junctions, pedestrian routes, lighting, weather and the space available. Signs need to give people enough time to understand and act on the information, without blocking pavements, cycle routes or visibility.

Signs should be positioned so they are clearly visible and relevant to the conditions ahead. They should not be obscured by parked vehicles, vegetation, street furniture or other signs. At night or in poor weather, visibility is especially important. The setup should also be checked regularly, as signs and equipment can be moved, damaged or affected by changing site conditions.

Following UK requirements

Temporary traffic signs in the UK must be appropriate for the road and the purpose for which they are being used. The design and use of traffic signs are governed by legal requirements and guidance, including the Traffic Signs Regulations and General Directions and relevant traffic-management guidance. The requirements can vary according to the road, the activity and the type of restriction.

Roadworks on public highways may require approval or coordination with the relevant highway authority, as well as suitable arrangements for traffic and pedestrian safety. Organisations planning work should check the requirements that apply to their location and activity, and use competent people to plan and manage the traffic arrangements.

Choosing temporary road signs

When selecting signs, consider the message, the road environment and how long the signs will be in place. Signs should be clear, durable and suitable for outdoor use. They should be stable in the conditions in which they will be used and positioned using appropriate supports or traffic-management equipment.

It is also important to keep the message simple. Too many signs or conflicting instructions can make a layout harder to understand. A logical sequence helps road users recognise a change, respond to it and continue safely through or around the affected area.

Installation, inspection and removal

Temporary signs should be installed in a planned order and checked before the site or route is put into operation. During the work or event, regular inspections can identify signs that have become dirty, damaged, obscured or displaced. If conditions change, the traffic-management arrangement may need to be reviewed.

When the restriction is no longer needed, signs and other temporary equipment should be removed as soon as it is safe to do so. Leaving outdated signs in place can create confusion and undermine confidence in important instructions.

Getting temporary traffic management right

Effective temporary road signs are more than a set of boards by the roadside. They form part of a wider plan that considers road users, site conditions and the risks created by temporary changes. With suitable planning, clear communication and regular checks, temporary signs can help people travel safely and confidently around works, events and other disruptions.

What are temporary road signs used for?

Temporary road signs are used to warn road users about hazards, changes or restrictions that will only be in place for a limited time. They can guide traffic around roadworks, closures and events, indicate temporary speed limits, and direct pedestrians and cyclists along safe alternative routes. Clear, correctly positioned signs help people understand what to expect and how to travel safely through or around the affected area.

Who is responsible for putting up temporary road signs?

Responsibility for putting up temporary road signs depends on the location and reason for the signs. For roadworks, the contractor or organisation carrying out the work will usually arrange the signs and traffic management, in coordination with the relevant highway authority. For events or other temporary restrictions, the organiser may be responsible for arranging approved signage and any required permissions. On public roads, signs must comply with applicable regulations and authority requirements, so responsibilities should be confirmed before installation.

Do temporary road signs need approval from the local highway authority?

Often, yes. If temporary road signs are to be placed on or affect a public highway, you may need permission from, or to coordinate with, the relevant local highway authority. Requirements depend on the location and the type of work or restriction; road closures and other traffic restrictions may also require a formal order or notice. Signs should comply with applicable UK regulations and guidance. Check with the highway authority before installation, as arrangements on private land may differ.

How far in advance should temporary road signs be placed?

Temporary road signs should be placed far enough ahead for road users to see, understand and safely respond to the warning or instruction. The appropriate distance depends on factors such as traffic speed, visibility, road layout and the type of hazard; there is no single distance that suits every situation. For roadworks on public highways, follow the relevant UK traffic-signing guidance and any requirements set by the highway authority, and check that signs remain visible and unobstructed.

What types of temporary road signs are used at roadworks?

Temporary road signs at roadworks can include advance warnings of works ahead, temporary speed limits, lane-closure and lane-shift signs, road-closed and diversion signs, and instructions for pedestrians and cyclists. Depending on the layout and traffic conditions, temporary traffic signals, priority signs and warnings of hazards such as uneven surfaces or loose materials may also be used. The signs should be selected and positioned to suit the site, clearly guide road users and meet relevant UK requirements.

How often should temporary road signs be checked?

Temporary road signs should be checked regularly throughout the time they are in use, with the frequency based on the site, traffic conditions and level of risk. They should also be inspected after severe weather, an incident or any change to the work area, and promptly if someone reports a problem. Checks should confirm that signs are visible, legible, correctly positioned, stable and still relevant; any damaged, obscured or outdated signs should be fixed or removed without delay. Follow the inspection arrangements set out in the site’s traffic-management plan and any applicable highway-authority requirements.

When should temporary road signs be removed?

Temporary road signs should be removed as soon as the work, event or hazard they relate to has ended and it is safe to do so. Leaving signs in place when they are no longer relevant can confuse road users and undermine other traffic instructions. Where conditions change in stages, update or remove signs promptly to reflect the current arrangements, following any requirements set by the relevant highway authority.
