If you want to register a vehicle (car, motorcycle) with a registration authority in Germany, you need to take out a car insurance for the vehicle. Without such insurance, registration is not possible.

In addition to the statutory insurance, you can also take out numerous private insurances. Private liability insurance is particularly important, for example.
