1.    Proof of financial responsibility may be furnished by filing with the director the written or electronically transmitted certificate of any insurance carrier duly authorized to do business in this state certifying that there is in effect a motor vehicle liability policy for the benefit of the person required to furnish proof of financial responsibility. Such certificate must give the effective date of such motor vehicle liability policy, which date shall be the same as the effective date of the certificate, and must designate by explicit description or by appropriate reference all motor vehicles covered thereby, unless the policy is an operator’s policy.

2.    When a certificate is filed showing that a policy or policies have been issued covering certain described motor vehicles or a limited operator’s policy but not insuring such person when operating all other motor vehicles, the director shall designate suitable restriction upon the driver’s license of such person authorizing the operation of only such vehicles as are covered by the certificate. It is unlawful for such person to operate any motor vehicle not covered by such certificate. In the event a person desires to be relieved of the foregoing restriction and to be permitted to operate any motor vehicle, the person may have such restriction removed upon filing a certificate showing that there has been issued to the person a motor vehicle liability policy insuring the person against liability arising out of the use of any motor vehicle.
