California Uninsured Motorist Coverage: What Drivers Need to Know

Updated September 10, 2026

Originally published March 18, 2019

California uninsured motorist coverage pays for your medical bills, lost wages, and vehicle repairs when the driver who hit you has no insurance at all, or not enough to cover what you actually lost. It’s optional under California law, but with more than 1 in 5 California drivers carrying no insurance, skipping it is a real financial gap for most families.

At Batta Fulkerson, we’ve recovered nearly $250 million for San Diego clients with a 98% success rate across 15,000+ cases, including a steady stream of claims where the at-fault driver turned out to be uninsured or underinsured. Paul Batta and Dan Fulkerson built this firm on exactly these cases: the ones where the paperwork looks simple until you find out the other driver’s policy doesn’t exist or doesn’t stretch far enough.

What Is California Uninsured Motorist Coverage?

Uninsured motorist (UM) coverage is an optional add-on to your own auto insurance policy. It steps in when another driver causes an accident but has no liability insurance to pay for the damage. Instead of being left to cover your own medical bills, lost income, and vehicle repairs out of pocket, you file a claim against your own policy’s UM coverage.

California auto policies typically split this into two types:

• Uninsured motorist bodily injury (UMBI): Covers medical bills, lost wages, and pain and suffering for you and your passengers.
• Uninsured motorist property damage (UMPD): Covers repairs to your vehicle and damaged property inside it.

California’s New Minimum Insurance Requirements

California’s minimum liability limits had been frozen at $15,000 per person / $30,000 per accident for bodily injury and $5,000 for property damage since 1967. Under Senate Bill 1107, those minimums rose to $30,000 / $60,000 / $15,000, effective January 1, 2025, with a further increase to $50,000 / $100,000 / $25,000 scheduled for 2035.

What SB 1107 did not do is require uninsured or underinsured motorist coverage. UM/UIM is still optional in California. Insurers are required to offer it and you have to decline it in writing, but plenty of drivers skip it without realizing what it actually protects against.

How Common Are Uninsured Drivers in California?

According to the Insurance Research Council’s most recent report, 20.4% of California drivers carried no auto insurance in 2023, putting California among the eight highest states in the country for uninsured drivers. On top of that, the IRC estimates roughly 18% of drivers nationally carry liability limits too low to fully cover a serious accident, meaning the realistic odds of dealing with an uninsured or underinsured driver in California are higher than most people assume.

What Is Underinsured Motorist Coverage?

Underinsured motorist (UIM) coverage works alongside UM coverage, but covers a different gap. It pays out when the at-fault driver does have insurance, but their policy limits fall short of your actual damages. For example, if a driver carrying California’s new $30,000/$60,000 minimum causes a crash that results in $80,000 of medical bills, your UIM coverage can help make up the difference once their policy pays out its maximum.

Most California insurers bundle UM and UIM coverage together on the same policy limits, so when people talk about “uninsured motorist coverage,” they usually mean both.

How Much Coverage Should You Carry?

There’s no one-size-fits-all number, but a few things are worth weighing:

• Your UM/UIM limits are generally capped at whatever bodily injury liability limits you carry on your own policy, so raising one often means raising both.
• Many attorneys recommend at least matching California’s new $30,000/$60,000 minimum, and carrying $100,000 or more per person if your budget allows it, since serious injuries routinely exceed the state minimum many times over.
• The added premium for higher UM/UIM limits is usually modest compared to the protection it buys, since insurers price this coverage based on your own driving record rather than other drivers’ behavior.

What Happens After an Accident With an Uninsured Driver?

The claims process starts the same way any accident claim does, then branches once the other driver’s insurance status comes into question:

1. Report the accident to your own insurance company and request a police report, which documents the other driver’s lack of coverage.
2. Confirm the at-fault driver’s insurance status. Your insurer will verify whether the other driver actually has no coverage or is simply underinsured for your damages.
3. File your UM/UIM claim with your own insurance company. You’re dealing with your own insurer here, not the at-fault driver’s, even though you weren’t the one who caused the crash.
4. Document your damages thoroughly: medical records, lost wage documentation, repair estimates, and any other financial impact of the accident.
5. Negotiate or dispute the settlement. Your own insurer still has a financial interest in paying out as little as possible, so a low initial offer on a UM claim is common, not unusual.

That last step is where a lot of people run into trouble on their own. Your insurance company isn’t on the other side of the case, but it isn’t purely on your side either, and a UM claim can turn adversarial fast if the injuries are serious.

Frequently Asked Questions

Is uninsured motorist coverage required in California?

No. California requires liability insurance but does not require uninsured or underinsured motorist coverage. Insurance companies must offer it, and you have to reject it in writing if you don’t want it, but carrying it is your choice.

How much does uninsured motorist coverage cost in California?

Uninsured and underinsured motorist coverage is usually one of the cheaper add-ons on a California auto policy, often adding well under $100 a year for meaningful protection. The exact cost depends on your driving history, your insurer, and the coverage limits you choose.

What’s the difference between uninsured and underinsured motorist coverage?

Uninsured motorist coverage pays out when the at-fault driver has no insurance at all. Underinsured motorist coverage pays out when the at-fault driver has insurance, but their policy limits aren’t enough to cover your damages. Most California policies bundle both together as UM/UIM coverage.

How much uninsured motorist coverage should I carry?

Many attorneys recommend carrying UM/UIM limits that at least match your own liability limits, and ideally higher. Given how quickly medical bills and lost wages add up after a serious crash, coverage in the range of $100,000 or more per person is worth pricing out against the small increase in premium.

What if the uninsured driver who hit me has no money or assets?

This is exactly the gap uninsured motorist coverage is built for. Suing an uninsured driver personally rarely recovers much, because a driver without insurance often has few collectible assets. Your own UM coverage lets you make a claim against your own policy instead of chasing a judgment you may never collect.

Do I file a claim with my own insurance company for an uninsured motorist accident?

Yes. You report the accident and file the UM claim with your own insurer, even though you weren’t at fault. Your insurance company investigates and pays your claim under the uninsured motorist portion of your own policy, then can pursue the at-fault driver separately if it chooses to.

Common Myths About Uninsured Motorist Coverage

A few misconceptions keep California drivers from carrying uninsured motorist coverage, or from using it correctly after a crash:

• “My health insurance will cover it.” Health insurance pays medical bills, but it won’t touch lost wages, pain and suffering, or the portion of your bills your health plan doesn’t cover. Uninsured motorist coverage fills all of those gaps.
• “If the other driver is uninsured, there’s nothing I can do.” This is exactly backward. An uninsured at-fault driver is the specific scenario uninsured motorist coverage exists for. Without it, you’re right that there’s little to collect. With it, your own policy pays.
• “Filing a UM claim will raise my rates like an at-fault accident would.” Most California insurers can’t raise your premium for a UM claim where you weren’t at fault, though it’s worth confirming your insurer’s specific policy on this.
• “I don’t need it if I have full coverage.” “Full coverage” usually means collision and comprehensive, which cover your car. It has nothing to do with covering your medical bills or lost wages after a crash caused by an uninsured driver.

Why an Insurance Claim Against Your Own Policy Can Still Get Complicated

It’s easy to assume that because you’re filing with your own insurance company, the process will be straightforward. In practice, your insurer is still a business with an interest in paying out as little as possible on your uninsured motorist claim, the same as it would be on any other claim. Common friction points include:

• Disputes over how much your injuries are actually worth, especially for soft-tissue injuries without a clear-cut diagnosis.
• Delays while your insurer tries to verify the at-fault driver’s coverage status, particularly when that driver has left the state or can’t be located.
• Lowball initial offers designed to see whether you’ll settle before getting a full picture of your medical treatment and recovery timeline.

None of this means a UM claim is a losing fight. It means it benefits from the same documentation and negotiation an attorney would bring to a claim against someone else’s insurance company.
