General information

General overview

Vehicles are eligible for operation in road traffic if they pass a main roadworthiness test (Hauptuntersuchung, HU) and an exhaust emissions test (Abgasuntersuchung, AU). Roadworthiness of a vehicle is attested by a certificate issued by the testing organisation or business and by a sticker (Prüfplakette). There is no specific form for the roadworthiness certificate. The sticker must be attached to the rear number plate. The sticker indicates the due date of the next inspection. The number in the middle represents the year. The number at the top indicates the month. The colour of the sticker changes each year according to a seven-year sequence.
