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 or HU) for vehicles, including caravan trailers, is mandated to ensure their safety and roadworthiness. When you leave a registered caravan trailer stationary on a campground for an extended period, the regular inspection requirements still apply.

The date on the test stamp indicates when the next inspection is due. This date must be observed regardless of the trailer's stationary status. Simply leaving it parked does not extend the validity of the test stamp.

It's essential to combine both aspects because the time the trailer is stationary does not alter its inspection schedule. This ensures that all vehicles on the road, even those that are parked for long periods, maintain compliance with safety regulations. Understanding this helps you stay responsible and adhere to traffic laws effectively.
