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

In Germany, having motor liability insurance for your vehicle is mandatory. The two key proofs of this insurance are the valid insurance number plate and the official evidence of insurance (Versicherungsbestätigung). The insurance number plate must be displayed on the vehicle, showing that the vehicle is insured, while the evidence of insurance is a document that confirms the insurance coverage. The permit for use (Betriebserlaubnis) is important for the vehicle's approval for road use but does not serve as proof of insurance. Together, the insurance number plate and the insurance evidence ensure you comply with legal requirements and can legally operate your vehicle on public roads.
