You will need this licence if you intend to operate a special passenger vehicle (SPV) for hire or reward. An SPV is a vehicle that is operated for a purpose that does not fall within any other category of commercial passenger vehicle.
Individual assessment of the proposed SPV service will apply, and limited operating areas and times may be imposed. SPV operators must not allow the vehicle to be made available for hire or reward if it is unsafe, e.g. bald tyres, frayed seatbelts etc.
