The most important thing to do firsthand is to check your own personal injuries and whoever was in your vehicle. If you are not okay, call an ambulance right away. When you have brought yourself over to a safer place (if possible), call the police and file a report. This is crucial, as a police report is how they will determine who is at fault and who is responsible for the crash. Then, it’s recommended that you get the other individuals who were involved in the crash name, phone number, and insurance information. You do not have to give a statement yet but getting the necessary information is important.
