Motorcycling is popular: there are around half a million motorcyclists in the Netherlands. Motorcycles are also used for recreational purposes as well as for commuting. A large number of motorcyclists ride for fun. However, you are not allowed to simply start riding a motorcycle - you need a Category A motorcycle licence first.
In order to obtain a motorcycle licence you must pass both a theory test and a practical test. If you already have a car driving licence (Category B licence) you are allowed to start practical motorcycle lessons immediately. If you do not yet drive, you must first obtain a category A theory certificate before getting on a training motorcycle.
