Under R.C. 3937.31, after a private passenger auto policy has been in effect more than 90 days, what is the minimum notice an Ohio insurer must give for mid-term cancellation for nonpayment of premium?

Why this is the answer

R.C. 3937.31 governs cancellation and nonrenewal of Ohio private passenger auto policies. After the first 90 days, the insurer may cancel mid-term only for statutorily enumerated reasons. For nonpayment of premium, the carrier must mail at least 10 days' written notice; other permitted cancellation reasons generally require 30 days' notice.
