Rising Bollards

In some town and city centres, certain streets may be closed for part of the day, either to all traffic (e.g. pedestrian zones) or to through traffic, with access permitted, for example, to public transport. Enforcement of these restrictions may be by the use of automatic bollards that rise from the ground to provide a physical closure. Where such bollards are in use, warning signs are normally provided. Where certain vehicles are allowed entry, red and green signals control the operation of the bollards. Only one vehicle should pass at any one time and may proceed only if the green signal is showing. Some vehicles, e.g. buses, have devices that can be recognised by detectors controlling the operation of the bollards. If you are not driving an authorised vehicle, do not follow the vehicle in front, as you may risk personal injury and damage to your own vehicle. Where pedal cycles are exempt, a separate route avoiding the bollards is normally provided.
