Convoy System

At some road works, other than on motorways, it may be necessary to slow traffic to a speed of 10 mph. To ensure the safety of both road users and the workforce, traffic is taken through the works in convoy. At the start of the convoy section, traffic is controlled by either traffic signals or ‘STOP/GO’ boards. You must wait, where indicated, for the convoy vehicle that will escort you though the works. On single carriageway roads you must not overtake the convoy vehicle. On dual carriageway roads you may overtake the convoy vehicle, if it is safe to do so, after you have passed through the works area and signs have indicated that the speed limit has changed to a higher limit. Where traffic signals are used at the start of the convoy section, the red signal may show for a period longer than you would normally expect: do not proceed until the green light shows. Convoy working may take place at any time during the day or night.
