Seasonal license plates are intended for all vehicles that are not used all year round. Their owners or keepers can thus save themselves the frequent registration and deregistration. Insurance coverage and the obligation to pay contributions are suspended during the period outside the operating period. The operating period is indicated on the right side of the license plate (e.g. 05/11 = the vehicle may be used from May to November).

When registering the vehicle, you specify once the period (from a minimum of two to a maximum of eleven months per year) during which you wish to use the vehicle. The vehicle may only be operated or parked in public traffic areas during the operating period shown on the license plate and in the Part I registration certificate. Outside this operating period, the vehicle must be parked on private property (e.g. in a garage).
