If the other driver denies fault after a car accident in Washington, that does not settle the question of who was legally responsible. It simply means liability is disputed, and the evidence becomes more important.
I see this issue in car accident cases more often than people might expect. At the scene, the drivers may have very different versions of the same collision. Sometimes those versions stay consistent. Sometimes they change after an insurance claim is opened. And sometimes an insurer accepts its driver’s account without initially having all of the information that tells the fuller story.
When I review a disputed-liability accident, I am not interested only in which driver sounds more confident. I want to understand what the physical evidence, photographs, witness statements, vehicle damage, collision report, available video, and other records show when they are considered together.
That is especially important because Washington follows a comparative fault system. A disagreement over fault is not necessarily an all-or-nothing issue.
A Driver’s Denial of Fault Is Not the Same as a Liability Decision
One distinction I often explain is the difference between what the other driver says and what can actually be established through evidence.
A driver might say:
- “They came into my lane.”
- “The light was green.”
- “They stopped suddenly.”
- “I never saw them.”
- “They were going too fast.”
- “They caused the accident.”
Those statements may become part of an insurer’s investigation, but simply saying something does not make it true.
The other driver’s insurance company will usually conduct its own investigation before taking a formal position on liability. Washington insurance regulations identify refusing to pay a claim without conducting a reasonable investigation as an unfair claims settlement practice.
That does not mean an insurer has to agree with you. It means a liability decision should be based on an investigation rather than simply on the insured driver’s preferred version of events.
From an attorney’s perspective, the question becomes: What evidence exists that can independently support or challenge those competing accounts?
One of the First Things I Look at Is What Everyone Said Early On
When I evaluate a disputed-liability collision, I want to understand what each driver said as close in time to the accident as possible.
The statements made at the scene can sometimes be very different from the position that develops later.
For example, a driver may initially say that they did not see another vehicle before changing lanes. Later, that same collision may be presented to an insurer as though the other vehicle unexpectedly entered their lane.
That type of inconsistency can matter.
I look at whatever reliable information is available, which may include:
- statements documented by responding officers;
- information provided to insurance companies;
- statements from passengers;
- independent witness accounts;
- photographs or video recorded immediately afterward; and
- other contemporaneous communications or records that help establish what occurred.
The goal is not to find one sentence and treat it as a “gotcha.” The goal is to build an accurate chronology and determine which version of events is most consistent with the rest of the evidence.
Vehicle Damage Can Tell Part of the Story
One reason I pay close attention to vehicle photographs is that the physical damage can sometimes help evaluate competing descriptions of a crash.
Suppose one driver says another vehicle struck them while changing lanes. The locations and directions of damage to the vehicles may become relevant when evaluating whether that account makes sense.
Depending on the circumstances, I may want to examine:
- the point of impact on each vehicle;
- photographs taken at the scene;
- post-collision vehicle photographs;
- repair estimates;
- the direction or pattern of visible damage;
- where the vehicles came to rest; and
- other physical evidence documented at or near the collision scene.
Vehicle damage does not automatically answer every liability question. Some crashes are relatively straightforward; others require more detailed reconstruction.
What matters is whether the physical evidence supports the account being presented.
Independent Witnesses Can Be Particularly Important
A neutral witness can become very important when each driver gives a different version of events.
When someone comes to me after a disputed accident, I want to know whether anyone other than the drivers saw what happened.
A witness may have been:
- driving immediately behind one of the vehicles;
- waiting at the same intersection;
- walking nearby;
- working at an adjacent business; or
- riding as a passenger in another vehicle.
I also want to know whether witness contact information was actually preserved.
That last point is easy to overlook. A person may stop, tell one of the drivers what they saw, and then leave without anyone getting a name or telephone number.
If witness information does exist, the details matter. I want to understand where the person was located, what they could actually see, and whether their account is consistent with the physical evidence.
Video Evidence May Resolve Questions That Memory Cannot
Video has become increasingly important in accident investigations.
Depending on where a collision occurs, potentially relevant footage might come from a dash camera, nearby business, residence, parking facility, or another source.
Not every collision will have usable video, and the existence or accessibility of footage depends entirely on the circumstances. But when liability is genuinely disputed, I consider whether there may be objective evidence that should be identified before it disappears.
That is one reason early investigation can matter.
For someone injured in a collision while traveling through Everett, Arlington, or elsewhere in Snohomish County, the scene may look very different days or weeks later. Vehicles are gone, debris has been removed, and witnesses continue with their lives. Potentially useful private video may also no longer be available.
Evidence is usually easier to identify when someone starts looking for it promptly.
How Much Does the Police Report Matter?
Police reports are useful, but I do not treat a collision report as the final word on civil liability.
A report may help identify the drivers and witnesses, document the location and circumstances, preserve statements, and provide other useful factual information.
Washington State Patrol also maintains systems through which eligible parties can request collision reports. When a collision is reported by a citizen without an officer investigating it, WSP specifically explains that the report itself is not investigated by local law enforcement or the Collision Records Section.
There is also an important legal distinction between using information from an accident investigation and assuming that the collision report itself will decide a civil case. Washington law restricts the use of required accident reports themselves as evidence in trials arising from the accident.
So when I review a police report, I am looking beyond a single box or conclusion.
I may be looking for:
- names and contact information for witnesses;
- statements attributed to the drivers;
- diagrams;
- the officer’s observations;
- the reported location and direction of travel;
- citations or other investigative information, when relevant; and
- leads that point to evidence that can be obtained separately.
A police report can be an important starting point. It is not a substitute for investigating the collision.
Washington’s Comparative Fault Rule Can Matter in a Disputed-Liability Claim
Washington follows a comparative fault rule.
Under RCW 4.22.005, fault attributable to an injured claimant proportionately reduces compensatory damages but does not automatically bar recovery.
That matters when the other driver’s insurer does not simply say, “Our driver was not responsible.” Instead, the insurer may argue that both drivers contributed to the crash.
For example, an insurer might accept that its driver made a mistake but still claim that the injured driver was partially responsible.
That creates two separate questions:
What actually caused the collision?
And, if more than one person’s conduct contributed:
How should fault be allocated?
When I evaluate a case like this, I want to understand the evidence supporting any allegation of comparative fault. I do not assume that a percentage assigned by an adjuster accurately reflects what happened simply because it appears in a claim file.
The specific facts matter.
What I Look for When an Insurer Is Investigating Fault
Insurance adjusters evaluate liability because it affects what, if anything, the insurer may be responsible for paying.
When liability is disputed, I pay attention not only to the insurer’s conclusion but also to the basis for that conclusion.
Questions I may consider include:
- Did the insurer speak with the available witnesses?
- Did it review photographs of both vehicles?
- Was video available?
- Did the insurer have the complete collision report?
- Is the insured driver’s current account consistent with earlier statements?
- What physical evidence supports the insurer’s version?
- Has the insurer identified specific evidence supporting an allegation that my client was partially at fault?
Washington’s Office of the Insurance Commissioner tells consumers that they should receive timely and clear explanations concerning claim decisions, and Washington regulations require reasonable claims investigations.
A disagreement does not automatically mean the insurance company has acted improperly. Sometimes reasonable people genuinely interpret the evidence differently.
But I want the liability decision to be based on the facts.
Disputed Liability Makes Evidence Preservation More Important
In my practice, disputed-liability cases are a good example of why I do not like treating personal injury claims as paperwork exercises.
If there is a genuine disagreement about how the collision occurred, the case may depend on evidence that needs to be identified, organized, and evaluated carefully.
That can include:
- photographs;
- videos;
- witness testimony;
- vehicle damage;
- electronic records when legitimately available and relevant;
- collision-scene evidence;
- medical documentation;
- insurance communications; and
- testimony from the people involved.
Sometimes one category of evidence is especially persuasive. More often, the picture becomes clearer only after several pieces are considered together.
My job is not simply to repeat my client’s version more loudly than the insurance company repeats its insured’s version. I want to develop the evidence that explains why one account is better supported.
What an Attorney May Do Differently in a Disputed-Fault Case
Not every disagreement after a collision requires an attorney.
But when fault has become a serious issue, legal representation can become useful because the problem is no longer simply submitting medical bills and waiting for an insurer to respond.
When I handle a disputed-liability matter, my work may involve developing a detailed chronology, obtaining available records, identifying witnesses, reviewing photographs and vehicle damage, examining the insurer’s stated liability position, and determining whether additional investigation is warranted.
I also think beyond the initial insurance claim.
Spencer Injury Law prepares cases knowing that a disputed issue may eventually need to be explained through litigation rather than resolved through an adjuster’s claim evaluation. That affects how I approach evidence from the beginning.
It is much easier to evaluate a case carefully when the underlying information has been preserved than to try to reconstruct what happened much later.
What If Both Drivers Believe They Had the Right of Way?
These cases often come down to evidence and credibility.
Imagine a collision where both drivers insist they entered an intersection with a green light. If there is no obvious physical evidence establishing which signal was displayed, the investigation may turn toward witnesses, video, the drivers’ statements, timing, lane positions, and any other reliable evidence available.
There may not always be one perfect document that answers the question.
From an attorney’s perspective, the job is to determine which facts can be established and how those facts fit together.
That is very different from assuming a claim is lost because the other driver refuses to admit fault.
A Disputed Story Does Not End the Investigation
The most important thing to understand is that another driver’s denial is only one piece of a much larger liability analysis.
When the other driver denies fault after a car accident in Washington, I look for independent evidence. I want to know what was said early, what the physical damage shows, whether witnesses exist, whether video may be available, what the collision investigation documented, and whether an allegation of comparative fault is actually supported.
Sometimes that investigation confirms that liability is genuinely uncertain. Sometimes it makes the circumstances much clearer.

Frequently Asked Questions
Does a Washington police report determine who is legally at fault?
Not by itself. A collision report can contain useful factual information, statements, witness details, and investigative leads, but it does not function as a civil court judgment establishing liability. Washington law also restricts the use of required accident reports themselves as evidence in trials arising from the accident.
What happens if there are no witnesses to the car accident?
The absence of an independent witness does not necessarily make liability impossible to establish. An attorney may evaluate vehicle damage, photographs, video, the drivers’ statements, scene evidence, and other available information. What evidence matters will depend on the type of collision and the specific facts.
Can I recover damages if I was partly at fault for a Washington accident?
Potentially. Washington’s comparative fault statute provides that fault attributed to a claimant proportionately reduces compensatory damages rather than automatically barring recovery. The amount of fault, if any, is a factual issue that depends on the circumstances of the collision.
What if the other driver’s insurance company denies liability?
An insurer’s denial does not necessarily determine what would happen if the dispute were evaluated through additional investigation or litigation. The next steps depend on the evidence, available insurance coverage, injuries and damages, and other circumstances. An attorney can review the basis for the denial and evaluate what options may exist.
