Yes, perforated film on the rear window is generally permitted in Germany—as long as the film used has the appropriate approval and is installed correctly. It is particularly important that rear visibility is not unduly restricted and that all technical requirements are met.
Additionally, please note that vehicles must have two functioning exterior mirrors if rear visibility is restricted—which is typically the case with perforated film.
The perforated film offered is suitable for use on vehicles and comes with an ABE marking (sticker), which must be affixed to the vehicle according to regulations.
In individual cases, the assessment may depend on the vehicle type, design, and installation. If you are unsure, it is recommended to consult with TÜV or the relevant registration authority.
