In a blue zone in Amstelveen a motorcycle (2 wheels) is parked without a parking disc. Next to it a car driver parks at 13:40 and sets the parking disc to 13:30. Who is doing it wrong?
Neither: 13:30 is the correct setting for the car
Only the car driver: the disc should be set to 14:00
Only the motorcyclist: a motorcycle also needs a disc
Explanation
False — you apply the disc duty to every vehicle. The parking disc is required for motor vehicles with more than two wheels; a two-wheeled motorcycle does not need one. The car driver does round the wrong way (Book p.165).
