What is the Hauptuntersuchung (HU or TÜV)?

In Germany, vehicles must be inspected regularly – usually every 2 years. If a vehicle does not pass inspection, it can’t drive on Germany roads. The inspection is very thorough. They check everything: lights, brakes, seats, seatbelts, horn, leaks, emissions, and much more.

This inspection is called the Hauptuntersuchung, but people sometimes call it TÜV. TÜV and Dekra are the authorities that inspect German vehicles.
