(a) In this section “warranty” means any provision of an insurance contract which has the effect of requiring, as a condition precedent of the taking effect of such contract or as a condition precedent of the insurer’s liability thereunder, the existence of a fact which tends to diminish, or the non-existence of a fact which tends to increase, the risk of the occurrence of any loss, damage, or injury within the coverage of the contract. The term “occurrence of loss, damage, or injury” includes the occurrence of death, disability, injury, or any other contingency insured against, and the term “risk” includes both physical and moral hazards.
(b) A breach of warranty shall not avoid an insurance contract or defeat recovery thereunder unless such breach materially increases the risk of loss, damage or injury within the coverage of the contract. If the insurance contract specified two or more distinct kinds of loss, damage or injury which are within its coverage, a breach of warranty shall not avoid such contract or defeat recovery thereunder with respect to any kind or kinds of loss, damage or injury other than the kind or kinds to which such warranty relates and the risk of which is materially increased by the breach of such warranty.
