Where do you find information on the permitted number of persons that can be transported in a passenger car?

Information about the maximum number of people that can be transported in a vehicle can be found in the registration certificate. It is entered in the field marked with the code 'S.1', which specifies the number of seating places including the driver's seat. According to Art. 63 para. 1 of the Road Traffic Act, carrying more people is prohibited and constitutes a serious offence.
