The Act Schedule 1: Enforcement powers Stopping and detaining vehicles
26.Paragraph 6 sets out the power the Act affords a constable in uniform, or an inspector accompanied by a constable in uniform, to stop and detain a vehicle or vessel. Such a power, however, may be exercised only for the purpose of exercising any of the other powers conferred by schedule 1, or conferred under a warrant granted under the schedule. Paragraph 6(5) provides a definition of “vehicle” that specifically includes a caravan. The power to stop and detain vehicles would therefore apply to the types of vehicles, e.g. caravans and mobile homes, which are commonly associated with a travelling circus. A vehicle or vessel may be detained for so long as is reasonably required to enable the constable or inspector to exercise the power in relation to which the vehicle or vessel was stopped. That power need not be exercised at the precise spot where the vehicle or vessel was detained, but somewhere nearby (for example, if that is safer or more convenient).
