Call 911 and remain at the scene until law enforcement arrives. Around here, that will likely be the Cincinnati Police, Hamilton County Sheriff’s Office, or Ohio State Highway Patrol. Get checked out by emergency medical personnel even if you feel okay. You could be suffering from a delayed pain injury, internal bleeding, vital organ damage, or broken bones and not even know it. As soon as you are able, see a doctor to protect your health and create an official medical record of your car accident injuries. Trauma care is available at places like Good Samaritan Hospital, University of Cincinnati Medical Center, and Midtown Urgent Care. You will also want to contact a lawyer right away to protect your right to compensation and get advice on how to proceed.
