Person collecting important evidence of their San Diego California Auto CollisionYou may believe you have an iron-clad case against the driver who caused your car wreck. However, you must be prepared to prove your right to compensation for injuries, lost wages, pain and suffering, and other damages.

Various types of evidence are the building blocks for developing a solid case. You can never have enough evidence, as our San Diego auto accident lawyer explains—and you must start collecting it immediately after the incident.

Common Types of Evidence You Need When Filing a San Diego Car Accident Claim

You need to prove the other driver’s negligence in causing your accident and your injuries, the seriousness of all damages, and the compensation you deserve. Here are some crucial forms of evidence that can help maximize your settlement.


Pictures can help prove the cause of the accident and vividly show all aspects of the damage. Take photos with your cellphone of the vehicles, accident scene, weather and road conditions, injuries, and anything else you think might be relevant. If you're too injured to do this, ask a passenger or witness to do it for you.

Police Report

The police report contains important details regarding the other motorist’s negligence, which helps position your case with their insurance company. Some of the information it may have included:

  • Contact information for the other driver and their insurance company
  • The other driver’s statement
  • Witnesses' contact information and, in some cases, their statements
  • Narration of how the accident occurred
  • Officer’s conclusions as to who was at fault
  • Any citations issued
  • Diagrams of the collision scene
  • Photographs

Vehicle’s Event Data Recorder

Some motor vehicles have a black box. Its data can provide information on the vehicle's speed, braking, steering, and other details that help establish the cause of your crash.

Your Clothes

You should save your clothes in the condition they were in after your accident. Take pictures of them, and then seal them in a plastic bag. If your case goes to trial, your clothes can be compelling evidence for the jury.

Witness Statements

Neutral bystanders who saw your accident can be strong witnesses who can corroborate how it occurred. If there were witnesses to your accident, get their contact information immediately. It's also critical to ask for their statements while their memories are fresh or before the individuals can't be found.

Expert Witnesses

If you were injured, you'll most likely need a medical expert. This physician will be able to explain how the accident caused your injuries, your past and future medical treatments, and your final prognosis.

Depending on the disputes in your case, you may need legal assistance to request other types of expert witnesses.

Common Expert Witnesses That Are Helpful in Car Accident Cases Include:

  • Accident reconstruction expert
  • Physical therapist
  • Vocational therapist
  • Engineer
  • Economic expert

Medical Records and Bills

Keep copies of your medical records to document injuries and treatments. Your medical bills help establish the expenses you paid for and what should be included in your settlement.

Paystubs and Income Tax Returns

If you cannot work during injury recovery, you're entitled to be compensated for wage losses. Your paystub and income tax returns help a knowledgeable car accident attorney determine the value of this portion of your claim.

Repair Bills for Your Vehicle

Keep your vehicle repair estimates and receipts to document the amounts necessary to include in your compensation package. Remember to save your receipts for towing costs, car rental fees, and any other property damage repair or replacement, and include them in your property damage claim.

Insurance Policies

You'll need a copy of the at-fault driver’s insurance policy to determine the amount of liability coverage he has to provide proper compensation for your claim. You should also review your carrier's policy for uninsured, underinsured, and other insurance coverages that might help fully compensate you if the other motorist has insufficient coverage—or none at all.

Let an Experienced Car Accident Attorney Collect the Evidence You Need

It can be overwhelming to think about collecting all this evidence alone. Fortunately, you don't need to do this by yourself. I can help you identify the evidence you need to hold the negligent driver accountable and assist you in pulling it all together. I'll also aggressively fight to pursue all the compensation you deserve.
