The policy shall provide property damage liability coverage with a limit of not less than $10,000. The policy also shall provide bodily injury liability coverage with limits of not less than $75,000 for each person and, subject to such limit for each person, total limits as follows:

(2) The department may not issue registration plates for such a vehicle unless there is on file with the department a certificate of insurance showing that the vehicle is insured in compliance with sub.

No such policy may be terminated prior to its expiration or canceled for any reason unless a notice thereof is filed with the department at least 30 days prior to the date of termination or cancellation. The department shall suspend the registration of a vehicle on which the insurance policy has been terminated or canceled, effective on the date of termination or cancellation.
