Anyone who suffers an injury in a car accident should be aware of some important evidentiary bases to cover in the aftermath of the crash. For example, the first thing an accident victim should do is seek medical treatment, as well as retain all medical documents and take pictures of any visible injuries. This kind of medical evidence can help prove the nature and extent of the injuries.
Whether it's you or your attorney, someone should return to the accident site and collect any available evidence, which in many cases is time-sensitive. The official police report can be helpful in building an injury claim, but the police report alone may not provide enough details to maximize the compensation for your injuries. In addition to the police report, it is a good idea to take multiple pictures of the accident scene at the time of day when the crash occurred. Photos should also be taken of the damage to your vehicle.
Witness statements can also be instrumental in proving another driver's negligence. Maybe a witness saw the at-fault party driving recklessly prior to hitting you, or maybe a witness can say with certainty that there was no sound of the driver applying brakes before the collision. While witnesses who actually saw an accident are very important, a witness doesn't have to provide a visual account of the crash for the witness statement to be valuable. Further investigation of the accident scene may also lead to interviews with witnesses who didn't initially speak with police.
Some crashes result from a number of contributing factors, all of which should be identified in a full investigation. You can learn more about these matters at our car accident overview.
