If you've been in a car accident in Fontana — on the 210, I-10, Cherry Avenue, or anywhere in San Bernardino County — the questions that follow tend to be the same: Who pays? How does a claim work? When does an attorney get involved? The answers depend heavily on California law, the specific facts of your crash, your insurance coverage, and the severity of any injuries.
Here's how the process generally works.
California is an at-fault state, meaning the driver responsible for the crash is generally responsible for damages. Unlike states with no-fault systems (where your own insurer pays first regardless of who caused the accident), California requires an injured party to pursue the at-fault driver's liability insurance — or pursue other available coverage.
California also follows pure comparative fault, which means your compensation can be reduced by your share of responsibility. If you're found 20% at fault, your recoverable damages are reduced by 20%. This applies even if you were mostly not at fault, and it shapes how insurers negotiate settlements.
| Claim Type | Who You File With | When It Applies |
|---|---|---|
| First-party | Your own insurer | Using your own coverage (UM/UIM, MedPay, collision) |
| Third-party | At-fault driver's insurer | Seeking compensation from the other driver's liability policy |
After a Fontana crash, most injured drivers begin with a third-party liability claim against the at-fault driver's insurer. The insurer will assign an adjuster to investigate — reviewing the police report, photos, medical records, and witness statements to determine fault and calculate a potential settlement.
In California personal injury claims, damages typically fall into two categories:
Diminished value — the reduction in your vehicle's market value after it's been repaired — is also a recognized category in California, though it requires documentation to support.
The value of a claim depends on injury severity, how clearly fault is established, the at-fault driver's coverage limits, and whether any of your own coverage applies. There is no standard formula, and outcomes vary widely.
Uninsured/Underinsured Motorist (UM/UIM): California law requires insurers to offer this coverage. If the at-fault driver has no insurance or insufficient limits, your own UM/UIM policy may cover the gap.
MedPay: An optional coverage that pays medical expenses regardless of fault — useful while waiting for a liability claim to resolve.
PIP: Personal Injury Protection is not standard in California the way it is in no-fault states, but MedPay provides some similar first-party medical coverage.
Collision coverage: Pays for vehicle repairs under your own policy, subject to your deductible, regardless of fault.
Treatment records are central to any injury claim. Insurers evaluate claims based on documented medical care — what injuries were diagnosed, what treatment was recommended, how long recovery took, and what costs were incurred.
Common post-accident care in Fontana claims includes emergency evaluation, orthopedic follow-up, chiropractic treatment, physical therapy, and sometimes specialist referrals for neurological or soft tissue injuries. Gaps in treatment or delays in seeking care are often cited by adjusters when disputing injury claims.
Personal injury attorneys in California almost universally take car accident cases on a contingency fee basis — meaning they receive a percentage of any recovery, typically in the range of 33% before a lawsuit is filed, though this varies. No fee is charged if there is no recovery.
Attorneys generally handle demand letters, insurer negotiations, evidence gathering, and — if necessary — filing a lawsuit. Legal representation is commonly sought in cases involving significant injuries, disputed liability, low insurance limits relative to damages, or situations where an initial settlement offer appears inadequate.
A demand letter typically outlines injuries, treatment, lost wages, and a settlement figure. Negotiation follows, and many cases resolve without litigation. Those that don't may proceed to mediation, arbitration, or civil court.
California generally allows two years from the date of injury to file a personal injury lawsuit, and three years for property damage claims. Different rules apply when government entities are involved — claims against public agencies in California typically must be filed within six months, a much shorter window.
These are general figures. The specific deadline that applies to your situation depends on who was involved, what type of claim is being filed, and other case-specific factors.
California law requires drivers to report an accident to the DMV within 10 days if the crash resulted in injury, death, or property damage over $1,000 — regardless of fault. Failure to report can affect your license. This is separate from any police report filed at the scene.
Drivers found to be uninsured at the time of an at-fault accident may face license suspension and may be required to file an SR-22 — a certificate of financial responsibility — to reinstate driving privileges.
The same crash can produce very different results depending on: how fault is allocated, what coverage each driver carries, how severe and well-documented the injuries are, whether a government entity bears any liability (a relevant factor on state highways or in areas with road defect claims), and how quickly the injured party sought and continued medical care.
None of those variables are uniform — and none of them can be assessed from the outside without a full review of the facts.
