If you are injured enough that you have to be hospitalized, make sure a loved one takes photographs of the damage to your vehicle. If you have injuries that are visible, such as severe lacerations,bruises, or open wounds, make sure that photographs are taken of your injuries as well. You also want to note the date on which the photographs of the vehicle and your injuries were taken.
Finally, make sure you report the accident to your own insurance company, even if the accident wasn't your fault. You do not need to use your own insurance benefits, but it is always a good idea to put your insurance company on notice of an accident, just in case the other driver doesn't have insurance and you need to use your uninsured motorist coverage in the future.
