2026 noch zum Pflichtcheck: Blaue Plakette? - Dann ist Ihr HU-Termin (über)fällig

Drivers who currently have a blue HU (Hauptuntersuchung) plaque on their vehicle's rear number plate should promptly schedule a check-up for their car. The month and year of the upcoming HU is not only indicated in the Vehicle Registration Certificate Part I (Fahrzeugschein), but also the color of the plaque signals the upcoming mandatory inspection.

With a blue plaque still visible, the clock is ticking - the 2026 inspection deadline is fast approaching. However, depending on the individual relevant month, this date might already be passed. It's possible that some drivers have missed this deadline, but it's crucial to understand how to read the plaque. Vehicles registered in 2026 must display a blue plaque with the number "27".

The months are displayed with additional bars and numbers from 1 to 12 arranged counter-clockwise, resembling the face of a clock. The month of the inspection deadline is always on the 12 o'clock position. For example, if an "11" is seen above, the plaque has been rotated so the 11th position represents November - thus, the HU is due for that month.

If the inspection is missed, fines and penalty points apply. In cases where the inspection is delayed by more than two months, drivers face a fine of at least 15 euros. If it exceeds four to eight months, drivers are fined 25 euros, and if it surpasses eight months, they face a 60 euro fine and a point in Flensburg. The HU inspection itself could become more expensive if the inspection is delayed.

The ADAC advises that late inspections may require a more thorough examination, increasing costs by 20 percent. However, even being early won't give drivers a bonus as the new plaque will only be valid from the date of the passed inspection.
