After a car hits you and leaves the scene, the first thing to do is call the police, and then collect as much information as possible, recommends DMV.org. The more information about the accident, the easier it is to file the police report and accident claim with the insurance company.
Important things to write down after the accident include the make, model and license number of the car that hit you. Write down the time the accident occurred, and look for any witnesses in the area and get their contact information. Make sure to take pictures of the damage to your car and the scene of the accident as this greatly helps you with the insurance company, notes DMV.org.
At this point in the accident, the police should have shown up and you can file a report. Include all the information you collected as well as any witness information. After the police report is finished, it is important to call your insurance company and let it know about the accident. If the driver of the hit and run is found, you can file the claim through his insurance company, states DMV.org. If the driver does not have insurance or is never found, file the claim through your insurance company. Some car insurance companies waive deductibles for hit and run accidents.
