An Illinois auto insurer decides not to renew a policy at its annual anniversary. Under 215 ILCS 5/143.17, the insurer must mail written notice of non-renewal at least how many days before the expiration date?

Why this is the answer

Under 215 ILCS 5/143.17(a), an Illinois insurer that does not intend to renew a personal auto policy must mail the named insured at least 30 days advance notice, keep proof of mailing, and also notify the producer and any lienholder. Section 143.17(e) requires a specific explanation of the reasons. If the insurer fails to give the notice, 143.17(c) keeps the policy in force until similar insurance procured by the insured takes effect.
