You were in an accident. You know what happened. You know the other driver ran the light, or changed lanes without looking, or was following too close. But now the other driver’s insurance company is saying you were at fault, or the police report lists you as the responsible party, and suddenly the compensation you expected is slipping away. If you’re in this situation anywhere in the Temecula, Murrieta, or greater Riverside County area, Attorney Dustin at Maricic Law Firm has handled this exact scenario more times than you’d think. And the answer to whether a fault determination can be changed is yes, it often can, but the window to build your case narrows quickly.
A Police Report Isn’t a Legal Verdict
Most people assume that whatever the police report says is final. If the responding officer wrote that you were at fault, that’s the end of the story. It’s not.
A police report is an officer’s assessment based on the information available at the scene. They arrive after the collision has already happened. They talk to both drivers, look at the vehicle positions, check for skid marks, and form an opinion. Sometimes that opinion is accurate. Sometimes it’s based on incomplete information, a more persuasive account from the other driver, or a misread of the physical evidence.
Police reports are not admissible as evidence of fault in California civil proceedings. They can be referenced during settlement negotiations, and insurance adjusters absolutely use them as a starting point, but they don’t carry the legal weight that most people believe they do. An officer’s fault assessment can be challenged with additional evidence that wasn’t available or wasn’t considered at the scene.
Attorney Dustin has worked cases where the police report assigned his client 100 percent fault and the outcome was reversed entirely during the claims process. The police report was a starting point, not the ending point.
How Insurance Companies Determine Fault (and Why They Get It Wrong)
When you file a claim against the other driver’s insurance company, their adjuster conducts an independent investigation. They review the police report, take recorded statements from both drivers, look at photos of the damage, and apply their own analysis to determine liability.
Here’s the part most people don’t realize: the other driver’s insurance company has a financial incentive to find you at fault. Every dollar they attribute to your negligence is a dollar they don’t have to pay. Their adjuster isn’t a neutral party. They work for the company that’s trying to minimize its payout. When the evidence is ambiguous or the police report is vague, that ambiguity almost always gets resolved in the other driver’s favor.
This is especially common in intersection collisions, lane-change accidents on the I-15, and rear-end situations where the lead driver was brake-checked or made a sudden stop. The default assumptions (the turning driver is always at fault, the rear driver is always at fault) are often wrong in practice but convenient for the insurance company to apply.
Your own insurance company can also assign you a percentage of fault under California’s pure comparative negligence system. California allows you to recover compensation even if you were partially at fault, but the amount is reduced by your percentage of responsibility. If the insurance company says you were 40 percent at fault on a $100,000 claim, your recovery drops to $60,000. That percentage allocation is negotiable, and shifting it even 10 or 20 points can mean thousands of dollars.
Evidence That Changes Fault Determinations
Fault determinations get overturned when new evidence contradicts the initial assessment. The types of evidence that most commonly shift liability include:
Traffic camera and surveillance footage. Intersections in Temecula, Murrieta, and along the I-15 corridor increasingly have traffic cameras. Nearby businesses often have exterior security cameras that capture adjacent roadways. This footage can directly contradict a driver’s account or an officer’s assumptions. But footage gets overwritten quickly, sometimes within 48 to 72 hours. Retrieving it before it’s gone is one of the most time-sensitive steps in any accident case.
Witness statements. The responding officer may have spoken to one or two witnesses at the scene, but other witnesses sometimes leave before the officer arrives or aren’t approached. A thorough investigation identifies additional witnesses from the accident location, nearby businesses, or other vehicles that were present.
Vehicle damage analysis. The location, angle, and severity of damage on both vehicles tell a story about how the collision occurred. A damage pattern that doesn’t match the other driver’s account of events is strong evidence that their version isn’t accurate. For example, if the other driver claims you merged into their lane, but the damage is on the front of their vehicle and the rear quarter panel of yours, the physics suggest they hit you from behind while you were already in the lane.
Cell phone records. If the other driver was using their phone at the time of the collision, their records can establish distraction. California law prohibits handheld phone use while driving, and evidence of texting or calling at the moment of impact shifts liability significantly.
Accident reconstruction. In more complex cases, a professional accident reconstructionist can analyze skid marks, vehicle rest positions, road conditions, and damage patterns to create a technical determination of how the accident occurred. This expert analysis carries substantial weight in settlement negotiations and at trial.
California’s Comparative Negligence System Works in Your Favor
California uses pure comparative negligence, which means you can recover compensation even if you were partially responsible for the accident. If you were 20 percent at fault, you recover 80 percent of your damages. If you were 50 percent at fault, you recover 50 percent.
This system means that even in cases where some degree of fault genuinely rests with you, reducing that percentage through additional evidence directly increases your compensation. The insurance company might initially assign you 60 percent fault. With proper investigation and documentation, that number might drop to 20 or 30 percent. On a case with $80,000 in damages, that shift from 60 percent to 20 percent is the difference between recovering $32,000 and recovering $64,000.
The insurance company knows this math too, which is why they start with the highest fault percentage they think they can justify. It’s a negotiating position, not a final answer.
Why Timing Matters When You’re Fighting a Fault Determination
Evidence disappears. Surveillance footage gets overwritten. Witnesses forget details or become harder to locate. Skid marks fade. The other driver’s insurance company locks in their position and becomes harder to move the longer the case sits without challenge.
California’s statute of limitations for personal injury claims is two years from the date of the accident. That’s the outer boundary. But the practical window for gathering the evidence that changes a fault determination is measured in days and weeks, not years. An attorney who starts investigating within the first week after an accident has significantly more to work with than one who picks up the case six months later.
How Attorney Dustin Approaches Fault Disputes
When a client comes to Maricic Law Firm with a fault determination they believe is wrong, Attorney Dustin starts by pulling every available piece of evidence: the police report, traffic camera footage requests, witness contact information, vehicle damage photos, and the client’s own account of what happened. He reviews the insurance company’s basis for their fault assessment and identifies the gaps in their analysis.
Because Attorney Dustin handles each case personally rather than passing it to a caseworker, he’s evaluating the evidence directly and building the argument himself. That matters in fault disputes, where the strength of the case depends on how well the evidence is assembled and presented to the adjuster. A strong demand letter backed by surveillance footage, an independent damage analysis, and witness statements forces the insurance company to reconsider a position they’d otherwise hold firm on.
Attorney Dustin has reversed fault determinations that initially looked unfavorable and recovered compensation for clients who were told they had no case. If the other driver’s insurance company is blaming you for an accident you didn’t cause, or assigning you a fault percentage that doesn’t match what actually happened, that determination is worth challenging.
