Wisconsin Statutes Vehicles (Ch. 340 to 351) § 344.34. Notice of cancellation or termination of certified policy

When an insurer has certified a motor vehicle liability policy under s. 344.31 or a bond under s. 344.36, the insurance so certified shall not be canceled or terminated until at least 10 days after a notice of cancellation or termination of the insurance so certified has been filed in the office of the secretary. No insurance so certified may be canceled or terminated by the insurer prior to the expiration of 90 days from the effective date of the certification on the grounds of failure to pay a premium when due. Such a certified policy or bond subsequently procured shall, on the effective date of its certification, terminate the insurance previously certified. Any certification or recertification filed by the same insurer following cancellation shall be accompanied by a fee of $3 payable by the insurer.
