What are the legal requirements for car window tinting films?

The legal requirements for car window tinting films in Germany are clearly defined to ensure both road safety and passenger comfort. Here are the key regulations and rules you should be aware of:

1. Light Transmission of the Windows:

• Windshield: The windshield generally cannot be tinted, except for a narrow strip (sun visor strip) at the top edge, as long as it does not impair the driver's view.
• Front Side Windows: These must have a light transmission of at least 70%. Tinting films are not allowed here and can result in fines.
• Rear Side Windows and Rear Windshield: From the B-pillar onward, these windows can be tinted darker. Dark tinting films are allowed, provided the vehicle is equipped with side mirrors on both sides.

2. General Type Approval (ABG):

• Required Certification: Car window tinting films must have a General Type Approval (ABG), confirming their legal status for road use.
• Carrying the Certificate: After installation, you should carry the installation certificate in the vehicle, confirming that the films meet the legal requirements.

3. Installation Regulations:

• Proper Installation: The films must be installed according to the manufacturer’s specifications and the ABG to ensure full functionality and legality.
• ABG Certification Mark and Visibility: The ABG certification mark with the corresponding number is laser-etched into the film and must be present on each window.

4. Traffic Inspections and Penalties:

• Regular Inspections: During traffic checks, the police verify compliance with the regulations. Illegal tinting films can lead to fines and the requirement to remove the film.
• Documentation: It is advisable to carry all relevant documents for installation and certification in the vehicle to quickly provide proof in the event of a check.

Summary:
The legal regulations for car window tinting films are strict and are intended to ensure road safety. Front and side windows (except for the sun visor strip) cannot be tinted, while darker tints are allowed from the B-pillar onward. A General Type Approval (ABG) is mandatory, and proper installation of the films is essential. For compliant installation, it is recommended to consult a professional.
