Any insurance policy, rider or indorsement hereafter issued and purchased to insure against any risk which may arise as a result of the application of this act, which contains any condition or provision not in compliance with the requirements of the act, shall not be rendered invalid thereby, but shall be construed and applied in accordance with such conditions and provisions as would have applied had such policy, rider or indorsement been in full compliance with this act, provided the policy is otherwise valid. The section shall not be construed to prohibit any such insurance policy, rider or indorsements from containing standard and customary exclusions of coverages which the insurance commissioner deems to be reasonable and prudent upon considering the availability and the cost of such insurance coverages.
