You have left your registered caravan trailer for six months during the winter on a campground. What applies as far as the official inspection (Hauptuntersuchung) is concerned?

In Germany, the official inspection (Hauptuntersuchung) date shown on the test sticker is fixed and must be observed regardless of whether the vehicle or trailer is stationary for a long time. There is no extension or pause of the inspection deadline simply because the caravan was not used or left on a campground. This ensures that all vehicles and trailers meet safety and environmental standards regularly, protecting road safety. Therefore, even if your caravan was parked for six months, you must still have it inspected by the original due date.
