If you are involved in a bus accident and you are injured, make sure either you or someone else has dialed 911 to request a rescue as well as the police to document the accident.
The bus driver should be creating a list of all the passengers on the bus at the time of the accident. Ensure that your name is written on the list, then take a picture of the list and the bus driver holding the list.
Ensure you receive a receipt showing proof that you were on the bus. Take a picture of the receipt to preserve it.
Take pictures of the damage to the bus, any vehicles involved in the accident, and/or any items damaged, i.e., a tree.
If you are injured, do not refuse medical attention. Be transported by rescue to the nearest or most appropriate hospital for treatment.
