A contractor maintains all the traffic signals on our behalf. Faults or failures will be reported to the contractor and will be fixed as soon as possible.
Some of the signals are able to report their faults or failure directly to an electronic monitoring station based in County Hall.
You can use the online form on this page to tell us about faulty street lights.
We have a responsibility for installing traffic signs and road markings to regulate traffic and provide warnings to road users of hazards ahead.
