What do you do after an accident? Find your license, registration and insurance card. Pray that they are all current. From there the cops will decide who is at fault (eventually.) Then we call the insurance company of the driver who is at fault. They handle it. If you go through your insurance company it effects your rating. Got that? But most of the other people you will be talking to about the accident will know what they are supposed to do.
I saw my cousin. Briefly. More later maybe.
BTW stupid drivers abound. Not my cousin. She's fine.
