How can you tell when you need to bring your vehicle in for its next vehicle roadworthiness test?

You selected both relevant options: looking at the inspection tag on the rear license plate and reading the entry made in the registration certificate Part I.

In Germany, these two methods are essential for determining when your vehicle needs its next roadworthiness test, known as "Hauptuntersuchung" (HU).

1. The inspection tag on the rear license plate provides a visual reminder of the due date. It shows the month and year in which the next test is required.
2. The registration certificate Part I contains official documentation outlining the vehicle's technical details, including the specific inspection dates and obligations.

Both sources provide necessary information to ensure compliance with German traffic regulations. It’s crucial to check both to avoid penalties and ensure the vehicle is roadworthy.
