Report a traffic light or signal problem

How to report a traffic light or signal problem including issues on puffin, pelican and toucan crossings, vehicle activated signs and signal controls at junctions.

Permanent traffic lights

You can report a problem with permanent traffic lights by calling Swarco on 0800 298 6815 between 8am and 4pm.

Outside of these hours, please call 0345 603 1433.

Please have the following information available:

  • parish or town
  • road name or number, for example B1078
  • type of traffic signal, for example pedestrian crossing
  • the type of fault (what's not working)
  • which direction you were travelling in
  • what side of the road is the traffic signal on

Repair of signals is prioritised based on the type of fault. This is to make sure that any fault that causes immediate danger is dealt with first, for example a red light that isn't working.

Temporary traffic lights

You can report a problem with temporary traffic lights, such as at roadworks, using the emergency contact details supplied at the site.

These contact details are normally published on the generator for the temporary traffic lights.

If you think Suffolk Highways are responsible for the temporary traffic lights you can contact Customer Service.
