Introduction
This booklet does not cover portable pedestrian crossing facilities. See Traffic Advisory Leaflet 3/11:
Signal-controlled pedestrian facilities at portable signals for advice on the use of these facilities.
The leaflet is available from the Department’s website at
www.gov.uk/government/publications/signal-controlled-pedestrian-facilities-at-portable-traffic-signals
You, or your supervisor, will need to discuss the placing of portable traffic signals with the traffic
authority. Permission in writing will be required, and express approval to the placing of the signals at
a particular site may be needed. If the permission/express approval gives positions for signal heads
etc., it is important that the layout follows those instructions. Lack of permission/approval and/or
incorrect layout may make the site unlawful. You, or your supervisor, should check if in doubt.
If the works are close to or are likely to affect level crossings, permanent signal-controlled junctions
and controlled crossings (including Zebras), the traffic authority must be involved before you proceed.
In the case of level crossings, the railway authority must also be involved at an early stage.
