Temporary traffic signals are a vital part of modern traffic management, helping to keep road users safe and traffic moving efficiently during roadworks, planned events, or emergency situations. They are most commonly used when traffic needs to be controlled in multiple directions but the available road space is reduced to a single lane.
 

When planning the use of temporary signals, several factors are taken into account, including traffic volumes, road type, visibility, and the presence of nearby junctions or side roads that may be affected by the works.
 

Why Temporary Traffic Signals Are Used

• Carriageway obstructions – when one lane is closed for resurfacing, utility repairs, or construction works.

• Managing traffic flow – ensuring vehicles from each direction pass safely where the road is restricted.

• Protecting road users and workers – reducing risk by clearly controlling vehicle movements around the work zone.

• Emergency response – quickly introducing safe traffic management following accidents, road damage, or infrastructure failures.

• Event management – providing safe and controlled access where temporary events affect the usual flow of traffic.

Temporary signals are also frequently required where works are located close to, or across, a set of permanent traffic lights. In these cases, our signals can be configured to mirror or temporarily replace the existing lights to prevent conflicting signals and maintain clear, safe guidance for road users. Where required, temporary pedestrian crossings can also be installed to provide safe access for all highway users.
 

Keeping Roads Moving

By using temporary traffic and pedestrian signals, CHM Group ensures the highest standards of safety, compliance, and efficiency. These systems help to minimise disruption while keeping vehicles, cyclists, and pedestrians moving as smoothly as possible during periods of change on the road network.
 

Did you know? There is no upper traffic count limit on the use of temporary traffic signals. This means they can be deployed on even the busiest of roads while remaining fully compliant with UK regulations.
