How Is Fault Determined After a Car Accident in Utah?
After a car accident, one question decides almost everything about your claim: who was at fault? In Utah, that answer is rarely a simple yes or no. Fault can be split between drivers, and the percentage assigned to you directly controls how much you can recover.
Utah uses a modified comparative negligence rule. You can recover damages as long as you are less than 50% at fault, but your compensation is reduced by your share of the blame. At 50% or more, you generally recover nothing.
How Utah’s comparative negligence rule works
Utah does not require you to be completely blameless to recover. Instead, fault is assigned as a percentage to each party. If you are found 20% responsible for a crash, your recovery is reduced by 20%. But cross the 50% threshold, and Utah’s rule bars you from recovering at all, which is exactly why insurers work so hard to shift blame onto you.
Who actually decides fault?
Fault is not determined by a single authority. Several parties weigh in, and they do not always agree:
- The police document the scene and may note a probable cause or issue a citation, persuasive, but not the final word.
- The insurance companies conduct their own investigations, and each has a financial interest in the outcome.
- Attorneys and accident reconstruction experts can challenge a flawed fault finding with physical evidence.
- A judge or jury makes the final legal determination if the case goes to court.
The evidence that establishes fault
The police report
An officer’s account of the scene, statements, and any citations is often the starting point for every insurer’s analysis.
Photos and physical evidence
Vehicle damage, skid marks, road conditions, and debris fields can confirm or contradict a driver’s version of events.
Witness statements
Neutral third parties who saw the crash can be decisive when the two drivers tell different stories.
Video and expert analysis
Traffic cameras, dashcams, and reconstruction experts can settle disputes that eyewitnesses alone cannot.
The insurer may try to pin part of the blame on you. Because even a small percentage of fault reduces your payout, and 50% erases it, assigning you blame is one of the most common ways to devalue a claim. Do not accept a fault finding at face value.
Frequently asked questions
Can I still recover if I was partly at fault?
Yes, as long as you are less than 50% at fault under Utah law. Your recovery is simply reduced by your percentage of blame. At 50% or more, you generally cannot recover.
Does a police citation mean I’m automatically at fault?
No. A citation is strong evidence but not a final legal determination of fault. It can be challenged with other evidence, and fault for the civil claim is decided separately.
What if the other driver lies about what happened?
This is common, and it is exactly why physical evidence, photos, and witnesses matter. An attorney can gather proof that counters a false account before it hardens into the insurer’s position.
