At what monthly interval must trucks with a permissible total mass exceeding 3.5 t be presented for official inspection (Hauptuntersuchung)?

Trucks with a permissible total mass exceeding 3.5 tons must undergo an official inspection, referred to as Hauptuntersuchung, at intervals of 12 months according to German traffic regulations. This requirement is in place to ensure that vehicles meet safety and environmental standards. Regular inspections help identify potential issues early on, promoting safety on the roads and reducing the risk of accidents caused by mechanical failures. Adherence to this regulation is essential for vehicle owners and contributes to overall traffic safety. It is important to remember that other categories of vehicles may have different inspection intervals, so always check the specific rules applicable to each vehicle type.
