OHIO AUTO INSURANCE GUIDE

Ohio Stacking & Multiple Insurance Policies

Ohio law permits motor-vehicle insurance policies to include anti-stacking provisions for UM/UIM coverage. Under Ohio Rev. Code § 3937.18, policies may limit recovery when multiple vehicles, policies or coverages could otherwise apply.

  • Identify every potentially applicable policy before applying anti-stacking language.
  • Review the actual other-insurance, anti-stacking and reducing provisions.
  • Determine insured status separately under each policy.
  • Do not assume multiple policies or premiums automatically produce additive UM/UIM limits.
