When an accident occurs, if you have the opportunity, it is in your best interest to take photographs of the accident scene, along with any noticeable injuries that you suffered from.
It can be hard to remember exact details of an accident, and you know what they say, a picture is worth a thousand words.
When you have pictures of the damages and injuries that were suffered, it will be hard for the at-fault driver to downplay the damages to the insurance company.
