You need our permission to erect temporary traffic signals on the highway.
You will need a traffic management plan drawn up by an accredited traffic management company before you apply. The plan must include signal timings, see Department for Transport's introduction to the Use of Portable Vehicular Signals.
You must also check for any other highway licences you might need and make sure you apply within the relevant time frames for each.
The cost of temporary traffic management with no excavation is £297.
The operation of temporary traffic signals is covered by part 9 of the Highways Act 1980 (external link).
Please note: Transport for Greater Manchester are responsible for switching on or off of existing permanent signals.
