An estimated one in six California drivers carries no insurance. When one of them hits you, the driver you would normally sue has nothing to pay a judgment with. That is where your own uninsured motorist coverage takes over, and it is why an uninsured motorist accident lawyer in Los Angeles builds your claim against your own insurance company instead of the other driver. At Borna Houman Law, we handle uninsured and underinsured motorist (UM/UIM) claims across Los Angeles County, from Downtown to the San Fernando Valley.
Key Takeaway: If an uninsured or underinsured driver hurt you in Los Angeles, California Insurance Code section 11580.2 lets you recover from your own UM/UIM policy. You have two years from the date of the crash to file suit, formally demand arbitration, or agree to arbitration in writing, or the claim is barred. California places no cap on your pain and suffering damages.
What does uninsured motorist coverage pay for in California?
Uninsured motorist (UM) coverage pays your injury damages when the at-fault driver has no liability insurance or cannot be identified. Underinsured motorist (UIM) coverage pays when the at-fault driver has insurance, but not enough to cover what your injuries are worth. Both are governed by California Insurance Code section 11580.2, and both are first-party claims, meaning you file against your own carrier.
California does not require drivers to buy UM/UIM coverage, but insurers must offer it, and you can only waive it in writing. If you never signed a waiver, you almost certainly have it. In our experience, most drivers who think they lack UM coverage actually have it and never knew, because the offer was buried in the application.
The two coverages solve different problems. Here is how they line up.
| Feature | Uninsured Motorist (UM) | Underinsured Motorist (UIM) |
|---|---|---|
| When it applies | At-fault driver has no insurance, or is a hit-and-run | At-fault driver has insurance below your damages |
| Who you claim against | Your own insurer | Your own insurer |
| Governing statute | Ins. Code 11580.2 | Ins. Code 11580.2(p) |
| How disputes are resolved | Binding arbitration | Binding arbitration |
| Common trap | Two-year deadline to demand arbitration | Settling with the other driver without consent |
How does underinsured motorist coverage actually pay out?
California UIM coverage is offset coverage, not stacked coverage. Your UIM limit is reduced by whatever the at-fault driver’s liability policy pays. This surprises most people, and it is the single most misunderstood part of the system.
Here is the math. Say the driver who hit you carried a 30,000 dollar liability limit and you carry 100,000 dollars in UIM. The other driver’s insurer pays its 30,000. Your UIM then covers the gap up to your limit, so you can recover another 70,000 from your own policy, for 100,000 total. If your UIM limit had been only 30,000, the offset would wipe it out and you would collect nothing extra.
The practical lesson is blunt: UIM only helps if your own limit is higher than the at-fault driver’s limit. Since Senate Bill 1107 raised California’s minimum liability limits to 30,000/60,000 on January 1, 2025, more at-fault drivers now carry 30,000, which means your UIM needs to sit well above that number to do any work. We tell every client to check their own declarations page the week they hire us.
What is the deadline to file an uninsured motorist claim in California?
You have two years from the date of the accident to protect a UM claim, and the deadline works differently from an ordinary injury lawsuit. Under Insurance Code section 11580.2(i), the claim is barred unless, within those two years, you either file suit against the uninsured driver, formally institute arbitration, or agree to arbitration in writing. Simply reporting the crash to your insurer does not satisfy the statute.
This is where good claims die. A client tells the adjuster about the crash, trades emails for eighteen months, and assumes the claim is alive because the insurer keeps talking. It is not. Talking is not a written arbitration demand. The most common mistake we see is treating a friendly adjuster as if the clock has stopped.
| Deadline | What triggers it | Authority |
|---|---|---|
| 2 years from the crash | File suit, demand arbitration, or agree to arbitration in writing (UM claim) | Ins. Code 11580.2(i) |
| 2 years from the crash | Personal injury lawsuit against an identified driver | CCP 335.1 |
| 6 months | Government tort claim if a public vehicle is involved | Gov. Code 911.2 |
| Policy notice period | Prompt notice of a hit-and-run, often within days | Your policy terms |
Why must you get your insurer’s written consent before settling?
Never sign a release with the at-fault driver’s insurer before your own UIM carrier consents in writing. If you settle and release the other driver, you can destroy your UIM claim, because your insurer loses its right to recover from the person who caused the crash. California Insurance Code section 11580.2 protects that subrogation right, and carriers enforce it.
The correct sequence is to notify your UIM insurer of the other side’s policy-limits offer, give it the chance to match the offer and preserve subrogation, and only then accept. This is a step a self-represented claimant almost never knows to take. In our experience, this one procedural move preserves more UIM money than any argument about the value of the injury.
The same care applies to a drunk driving crash, where the at-fault driver is frequently uninsured or carries a token policy, and UM/UIM becomes the real source of recovery.
How much is an uninsured motorist claim worth in Los Angeles?
An uninsured motorist claim is worth the same categories of damages as a lawsuit against an insured driver, because your UM coverage stands in the shoes of the driver who has no insurance. You recover medical bills, future care, lost wages, lost earning capacity, and pain and suffering, and California places no cap on that last category in an ordinary injury case.
Your own fault does not end the claim. California follows pure comparative negligence under Li v. Yellow Cab Co., so even a partially at-fault claimant recovers, reduced by their share of fault. A rider found 20 percent responsible for a lane-change crash still collects 80 percent of the damages.
| Damage category | What it covers | Cap in California |
|---|---|---|
| Medical expenses | Past and future treatment, surgery, therapy | None |
| Lost income | Missed work and reduced earning capacity | None |
| Pain and suffering | Physical pain, emotional distress | None (ordinary injury) |
| Recovery ceiling | Your UM/UIM policy limit | Set by your policy |
The one real ceiling is your policy limit. That is why a serious injury caused by an uninsured driver can still leave money on the table if you carried thin coverage, and why we review every layer of available coverage, including resident-relative policies and any commercial policy that might apply.
Do uninsured motorist claims go to court or arbitration?
Most UM disputes are decided by binding arbitration, not a jury. Insurance Code section 11580.2(f) builds an arbitration clause into every UM policy, so if you and your insurer cannot agree on fault or value, a neutral arbitrator decides. UIM claims usually follow the same path.
Arbitration cuts both ways. It is faster and more private than a lawsuit, but you are now adverse to your own insurer, and that company knows the file better than you do. When an insurer lowballs a clear claim or drags out payment in bad faith, California law lets you pursue a separate bad-faith claim beyond the policy limit, though those cases are fact-specific and demand real evidence of unreasonable conduct.
Because a UM claim is really a fight with an insurance company, the work looks a lot like any other serious injury case. See how we approach a Los Angeles car accident lawyer matter and the broader personal injury cases we handle across the county.
Frequently asked questions about uninsured motorist claims
Will my rates go up if I file an uninsured motorist claim?
California law prohibits an insurer from raising your rates or canceling your policy for filing a UM claim when you were not at fault. Insurance Code section 491 bars surcharges on not-at-fault claims. If your carrier tries it, that itself can be a violation.
What if the driver who hit me fled the scene?
A hit-and-run is treated as an uninsured motorist claim, so your UM coverage applies even though the driver is never found. California generally requires physical contact between your vehicle and the phantom vehicle for a hit-and-run UM claim, so a crash caused by a car that forced you off the road without touching you is harder to prove. Our Los Angeles hit-and-run accident lawyer page explains the physical-contact rule in detail.
Can I file a UM claim if I was a passenger, pedestrian, or cyclist?
Yes. UM coverage follows the person, not just the car. If you were a passenger, or you were walking or riding a bike when an uninsured driver hit you, you can usually claim under your own policy, a resident relative’s policy, or the policy on the vehicle you were riding in. This is one reason to identify every household policy early.
What if I only carry the minimum coverage?
Then your recovery is capped at that minimum, which is now 30,000 dollars per person under SB 1107. That is often far below what a broken bone or a surgery actually costs. We still pursue every other available policy, but this is the reason we urge clients to carry UM/UIM limits that match the value of a real injury.
How long does an uninsured motorist claim take?
A straightforward UM claim can resolve in a few months once treatment is documented, while a disputed claim that goes to arbitration can take a year or more. The two-year statutory deadline under section 11580.2(i) controls the outside limit, so the demand for arbitration should go out long before then.
