Color codes and special markings are also used to ensure that the badge cannot only be read from a very short distance. Anyone who knows these codes can see at a glance when the next HU is due. Of course, the codes also help policeto quickly recognize whether a TÜV sticker has already expired.
Back to the HU in 2022? Then the TÜV sticker is brown
TÜV sticker color codes
This is how you can see in which month the HU is due
In addition to the color, the number in the middle of the badge also indicates the year in which the next inspection must take place (example: “23” means TÜV date in the course of 2023). The outer ring of numbers from one to twelve also shows in which month the exam is due. The number at the top of the plaque indicates the month. The plaque is always affixed to the license plate in such a way that the corresponding month is in the 12 o’clock position. If the six is at the top, the car has to go to the TÜV by the end of June.
Renewal of the TÜV sticker usually every two years
When the TÜV sticker has to be renewed depends on the type of vehicle. For example, motorcycles have to be presented to the testing organization every two years, and taxis and rental vehicles even every year. The first technical inspection was introduced in 1951, and only since 1960 has TÜV and its competitors DEKRA, GTÜ and KÜS taken on this task on behalf of the state.
