Start with safety: check for injuries and call 911 if anyone is hurt or the damage looks serious. Ohio law requires reporting accidents involving injury, death, or significant property damage. If you can safely move vehicles out of traffic, do so, and exchange license, insurance, and contact information with the other driver. Take photos of the vehicles, damage, and the accident scene, and gather contact information from any witnesses. Afterward, notify your insurance company and consider a medical evaluation even for injuries that don’t seem serious right away.
