Vehicles that are stolen must still be insured. Even if you have reported your vehicle as stolen and/or you have cancelled your insurance, the plates may not always have been deregistered. You must therefore make sure to deregister the plates yourself in writing on the Danish Motor Vehicle Agency’s website . You will have to pay the fee up to and including the day your vehicle is deregistered at the Danish Motor Vehicle Agency. This also applies even if you have cancelled your insurance. To deregister your vehicle in writing, go to the Danish Motor Vehicle Agency’s website .
