Uninsured & Underinsured Motorist Coverage in Nevada and California: What It Pays & What Kills a Claim

Published Jan 09, 2026 • Updated Jul 24, 2026

Summary: Uninsured/underinsured motorist (UM/UIM) coverage is the part of your own auto policy that pays when the driver who hit you has no insurance, not enough insurance, or drives off. Nevada and California both require insurers to offer it, and in both states it’s built into your policy unless you signed it away in writing. But the two states calculate the payout in opposite directions — Nevada stacks your coverage on top of the at-fault driver’s limits, California subtracts what that driver paid. Same crash, very different check.

Most people find out what UM/UIM coverage is on the worst day of their year. The crash already happened. The other driver has a lapsed policy, a $25,000 limit, or they ran and nobody got their license plate number. The question is suddenly very simple: who pays for this?

The answer is usually your own insurance company. Which means the company you’ve paid premiums to for years is now on the other side of the table. That’s not cynicism, it’s the structure of a uninsured motorist claim. Your insurer’s obligation is to you, and its interest is in paying you less.

Here’s how the coverage works in both states we practice in, and where claims quietly die.

What UM/UIM Actually Pays For

Uninsured motorist (UM) coverage applies when the at-fault driver has no bodily injury insurance at all, when their insurer denies coverage or goes insolvent, or when they flee and can’t be identified. Underinsured motorist (UIM) coverage applies when they have insurance, but their limits don’t come close to your damages.

Both cover medical bills, lost income, and pain and suffering — and both extend past the policyholder. Passengers in your car are covered. So are family members in your household, whether they’re driving, riding, walking, or on a bike. Neither covers punitive damages in Nevada or California.

The State Coverage Minimums Were Never Built for a Real Crash

Nevada requires 25/50/20: $25,000 per person for bodily injury, $50,000 per accident, $20,000 for property damage (Nevada Division of Insurance).

California raised its floor for the first time since 1967. As of January 1, 2025, Senate Bill 1107 set the minimum at 30/60/15, up from 15/30/5. It goes to 50/100/25 in 2035. That also raised the minimum UM/UIM limits insurers must offer.

Now hold those numbers against reality. The average new vehicle sold for $49,758 in June 2026 (Kelley Blue Book). One ambulance ride, an ER workup, an MRI, and a surgical consult will spend $25,000 before anyone discusses physical therapy or a missed paycheck.

And the drivers around you are worse off than you think. Nationally, 15.4% of drivers carry no insurance and 18.0% are underinsured — one in three, combined (Insurance Research Council, 2025). Nevada sits at 11.1% uninsured. California sits at 20.4% — eighth-highest in the country, roughly one in five (III).

Takeaway: You cannot control what coverage the driver next to you has, but you do control what coverage you have.

Nevada: Your Coverage Sits On Top

Under NRS 690B.020(1), no auto policy can be issued in Nevada without UM coverage unless you rejected it in writing, on a form the insurer provides. Under NRS 687B.145(2), insurers must offer UM/UIM equal to the bodily injury limits you bought, and every renewal must include the offer form again.

The part that matters most: Nevada follows an “excess” approach. Your UIM pays damages that exceed the at-fault driver’s bodily injury limits, up to your own limits (Mid-Century Ins. Co. v. Daniel, 101 Nev. 433). If they carry $25,000 and you carry $100,000 in UIM, you have $125,000 available — not $100,000.

Three more Nevada rules worth knowing:

• You don’t have to exhaust their policy first. The Nevada Supreme Court refused to make injured people turn down settlements and roll the dice at trial just to unlock their own benefits (Shaw v. Continental Ins. Co., 108 Nev. 928; White v. Continental Ins. Co., 119 Nev. 114). But your damages must exceed the at-fault driver’s limits — not just what you settled for.
• Arbitration clauses aren’t binding. NRS 690B.017 says an arbitration provision in a Nevada auto policy doesn’t bind you.
• Filing can’t be held against you. NRS 687B.385 bars insurers from canceling, refusing to renew, or raising your premium over a claim you weren’t at fault for. The fear of a rate hike keeps people from filing. Nevada law took that excuse away.

California: Your Coverage Fills a Gap

Insurance Code §11580.2 governs everything. UM is included unless deleted or reduced by written agreement. Insurers must offer limits matching your bodily injury coverage, though they aren’t required to offer above $30,000/$60,000.

California runs the math the other way. Under §11580.2(p)(4), your UIM carrier gets a dollar-for-dollar credit for everything the at-fault driver paid. Carry $100,000 in UIM, collect $30,000 from them, and your carrier’s maximum exposure drops to $70,000. Total recovery: $100,000, not $130,000.

Two conditions have no equivalent in Nevada:

• You must exhaust their limits first. §11580.2(p)(3). Settle for $28,000 of a $30,000 policy and you may have no UIM claim at all.
• You need written consent before you settle. §11580.2(c)(3) voids coverage if you settle with or take judgment against the at-fault driver without your insurer’s written consent. Signing a release the adjuster faxes over on a Friday can end a six-figure claim.

California also prohibits stacking entirely (§11580.2(q)), and sends UM disputes to a single neutral arbitrator rather than a jury (§11580.2(f)).

One more, and it’s brutal: under Civil Code §3333.4 (Proposition 213) an uninsured owner or driver cannot recover pain and suffering at all, even when the crash was entirely someone else’s fault, and even from their own UM carrier. Economic losses only. Passengers are exempt from this rule, and so are victims of a driver later convicted of DUI. Otherwise, a lapsed policy costs you the largest part of your claim.

Hit-and-Run: The Rule That Ends Most Claims

Both states cover hit-and-run through UM. Both impose a condition that catches people off guard: physical contact.

In Nevada, when the driver is unknown, NRS 690B.020(3)(f) requires that your injury resulted from physical contact with that vehicle, and that the crash was reported to police as required by NRS 484E.030. The Nevada Supreme Court enforced the contact requirement in Kern v. Nevada Insurance Guaranty, 109 Nev. 752.

California is stricter and clock-driven. Under §11580.2(b), you need physical contact, a police report within 24 hours, and a sworn statement filed with your insurer within 30 days. A driver forced off the road by a phantom vehicle that never touched her recovered nothing (Boyd v. Insurance Exchange, 136 Cal.App.3d 761).

Takeaway: “Contact” is read broadly — a clipped mirror, flying debris, a chain reaction through another car all count. But a near miss usually doesn’t. And in California, 24 hours is 24 hours.

Steps to Take After the Crash

1. Call 911 from the scene. Not later, not from home. In California, injury crashes must be reported to police within 24 hours (Veh. Code §20008). In Nevada, report without delay if no officer responds.
2. Get examined the same day. Adrenaline masks injuries, and a treatment gap is the first thing an adjuster will use against you.
3. Photograph everything. Both vehicles, the debris field, the road, your injuries. Get names and numbers from witnesses; in a hit-and-run, a bystander’s memory of a partial plate is often the whole case.
4. File the state report. Nevada: DMV within 10 days for injury or $750+ damage (NRS 484E.070). California: SR-1 to the DMV within 10 days for injury, death, or $1,000+ damage. Missing the SR-1 can suspend your license.
5. Open the UM claim promptly, and in writing. California hit-and-run claimants must file the sworn statement within 30 days.
6. Pull your declarations page. Find the UM/UIM line and the limits. If it says “rejected,” check whether anyone actually signed a compliant form.
7. Don’t sign a release or settle with the at-fault driver until someone reviews it. In California this can extinguish your UIM claim outright.
8. Watch the deadlines. Nevada: 2 years for the injury claim against the driver (NRS 11.190); the UM/UIM contract claim runs 6 years from denial. California: two years from the accident, and §11580.2(i) requires that within that window you file suit against the uninsured motorist, conclude an agreement, or formally demand arbitration by certified mail.

Frequently Asked Questions

Insurers know most people never read the UM section of their policy. They count on the 24-hour report being missed, the release being signed early, the low offer being accepted out of exhaustion. We read the policy, we hold the deadlines, and we make them account for every dollar of what you actually lost.
