Ohio Rev. Code § 3937.021: Relevant factors for determining rates.

In determining rates for motor vehicle insurance, an insurer shall not consider the fact that an applicant does not have motor vehicle insurance covering the applicant's motor vehicle at the time of his application for such insurance, unless the insurer has an actuarial justification. An insurer may consider any relevant factor contributing to the cancellation, refusal to renew, or other involuntary termination of motor vehicle insurance coverage previously maintained by the applicant, and may consider any other relevant factors permitted by sections 3937.01 to 3937.17 of the Revised Code.
