proving causation

You're sitting in the doctor's office three weeks after the accident, explaining how your back started hurting right after the crash. But the insurance adjuster wants proof—not just your word. They need evidence that connects your injury directly to that moment of impact, and without the right documentation, even legitimate claims can fall apart.

Seattle car accident lawyer Preet Kode and the team at Kode Law understand that proving causation requires more than good intentions and honest testimony. The right evidence transforms your experience into a compelling legal case that insurance companies take seriously.

What Types of Evidence Actually Matter in Court?

The strongest cases combine immediate documentation with ongoing medical evidence. Think of it as building a timeline—each piece of evidence adds another link that becomes harder to dispute.

Medical Records

Your medical records serve as the foundation of any injury claim, but timing matters enormously. Records created immediately after the accident carry more weight than those from weeks later, because they capture your condition before other factors could contribute to your pain.

Emergency room visits, ambulance reports, and urgent care records document your injuries in real time. These records often include statements about how the injury occurred, which helps establish the connection between the accident and your condition. Even if you felt fine initially, any mention of the accident in your medical history strengthens your case later.

Diagnostic imaging like X-rays, MRIs, and CT scans provide objective evidence that's difficult to dispute. Unlike subjective pain reports, imaging shows physical damage that existed at a specific point in time.

The Police Report

Police reports create an official record of the accident circumstances, vehicle damage, and any immediate injuries reported at the scene. The report often includes details about weather conditions, road hazards, and traffic violations—factors that help explain how the accident occurred and why certain injuries resulted. Insurance companies rely heavily on these reports when evaluating claims.

How Do You Document the Connection Between Impact and Injury?

Your goal is to create a clear timeline that connects the moment of impact to your current medical condition. This requires gathering evidence that shows the accident had enough force to cause your specific injury and that your symptoms appeared in a pattern consistent with trauma from the crash. Strong documentation eliminates doubt and makes it difficult for insurance adjusters to blame your injury on other factors—which is particular important for low-speed car accidents that can come across as less serious at first glance. 

Witness Statements That Support Your Version

Witnesses provide independent verification of both the accident details and your immediate condition afterward. Passengers, other drivers, and bystanders can testify about the severity of impact, your behavior immediately after the crash, and any obvious signs of distress or injury.

These statements become particularly valuable when your injury symptoms developed hours or days after the accident. Witnesses who saw you struggling to move, holding your neck, or appearing dazed help establish that something was wrong from the very beginning.

Photographic Evidence of Damage and Conditions

Photos of vehicle damage help establish the severity of impact, which correlates directly to potential injury severity. Extensive damage to your vehicle suggests forces strong enough to cause physical harm, while minimal damage might raise questions about causation.

Pictures of the accident scene, road conditions, and your visible injuries create a comprehensive visual record. Even bruises, cuts, or swelling that seem minor can become important evidence when they appear in the same areas where you're experiencing ongoing pain.

What Medical Evidence Proves Ongoing Injury in a Seattle Car Accident Case?

Insurance companies often minimize injuries by suggesting they're temporary or unrelated to the accident—particularly when symptoms persist for weeks or months. They may argue that your pain should have resolved by now or that ongoing problems stem from age, lifestyle, or preexisting conditions rather than the crash.

Seattle courts and insurance adjusters look for consistent, objective documentation that shows your condition directly resulted from the accident and continues to impact your life in measurable ways. The right medical evidence creates an undeniable record of how the crash continues to affect your health and daily functioning.

Treatment Records That Show Consistency

Consistent medical treatment creates a paper trail that's difficult to dispute. Regular doctor visits, physical therapy sessions, and follow-up appointments demonstrate that your injury requires ongoing care and hasn't resolved on its own.

Gaps in treatment can weaken your case. However, delayed treatment isn't automatically disqualifying if you can explain the delay through work obligations, insurance issues, or the gradual onset of symptoms.

Documentation of How the Injury Affects Your Life

Your medical records should include detailed descriptions of how your injury impacts daily activities, work performance, and overall quality of life. Functional limitations documented by healthcare providers carry more weight than your own descriptions of pain and difficulty.

Physical therapy notes, occupational assessments, and specialist evaluations provide professional opinions about your limitations and prognosis. These records help quantify damages and support claims for lost wages or reduced earning capacity.
