What proves that you have taken out a motor liability insurance for your vehicle?

Your selection of both the valid insurance number plate and evidence of insurance is correct. According to German traffic regulations, it is mandatory to have motor liability insurance for vehicles, and these two items serve as proof of insurance coverage.

The valid insurance number plate, which often shows a specific symbol or coding, indicates that the vehicle is insured and allows enforcement officers to quickly verify insurance status. Evidence of insurance, typically in the form of documentation from the insurer, provides confirmation of the insurance policy in effect.

It’s important to have both forms of proof on hand while driving to comply with legal requirements and avoid fines or penalties for operating a vehicle without valid insurance. The third option, the permit for use (Betriebserlaubnis), while necessary for vehicle legality, does not serve as proof of insurance and is therefore not part of the required documentation for demonstrating motor liability coverage.
