At first, you have to calm down. And Call the police office for enroll the accident. In my case, I called the police man to the accident place, but you don't need to do this. It's enought to enroll the accident to police office. Second, you have to request someone who happen the car accident to enroll the insurance for man and the car. And you receive the insurance number. Because you need the insurance number when go hospital and also fix the car. Last, Don't be lazy to go hospital. You can feel not bad and might be better faster than you thought. But you steadily have to go hospital a few weeks or more months.
