California uninsured motorist coverage can help protect you when an at-fault driver has no applicable bodily injury liability insurance or, in a qualifying underinsured-motorist case, has applicable bodily injury liability limits that are lower than your UM/UIM limits. California law generally requires this protection to be included with qualifying bodily injury liability policies unless the named insured makes a permitted written rejection or coverage election.[1]
Understanding this coverage requires separating bodily injury protection, underinsured motorist protection, property damage coverage, and California’s collision deductible waiver. Each works differently, so review the actual limits and selections shown on your policy rather than treating “uninsured motorist coverage” as one single benefit.
Understanding each UM/UIM selection is easier when you also consider how California auto insurance coverage choices work together across liability, physical damage, and optional protections.
California UM Coverage Can Be Rejected in Writing
California Insurance Code §11580.2 generally requires qualifying bodily injury liability policies to contain uninsured motorist coverage. A named insured and insurer may enter into a written agreement that deletes the coverage completely, excludes it when specified people operate a vehicle, or provides an allowed lower amount subject to California’s statutory requirements.[1]
What Is California Uninsured Motorist Coverage?
Uninsured motorist bodily injury coverage addresses certain damages an insured is legally entitled to recover from the owner or operator of an uninsured motor vehicle because of bodily injury or wrongful death. California law also includes qualifying underinsured motor vehicles within its UM/UIM framework.[1]
An underinsured motor vehicle is defined more specifically. Under California law, it is an insured vehicle whose applicable insurance amount is lower than the uninsured motorist limits carried on the motor vehicle of the injured person.[1]
The California Department of Insurance separately identifies uninsured motorist bodily injury, underinsured motorist protection, uninsured motorist property damage, and collision deductible waiver protection. Those distinctions matter because bodily injury and vehicle-damage claims follow different rules.[2]
UMBI, UIM, UMPD, and Collision Deductible Waiver
| Protection | What It Generally Addresses | Important California Detail |
|---|---|---|
| UMBI | Bodily injury caused by a qualifying uninsured motorist. | The insured must be legally entitled to recover damages, subject to the policy and California law. |
| UIM | Bodily injury involving an at-fault vehicle whose applicable liability insurance is lower than the injured person’s UM/UIM limits. | The applicable bodily injury liability limits generally must be exhausted before UIM applies. |
| UMPD | Damage to the insured vehicle caused by a qualifying uninsured motor vehicle when collision coverage is not included. | The statutory maximum is the vehicle’s actual cash value or $3,500, whichever is less. |
| Collision Deductible Waiver | The collision deductible after a qualifying collision involving the insured vehicle and an uninsured motor vehicle. | This protection is offered when the policy includes collision coverage. |
California Insurance Code §11580.26 separates the available property-damage protection according to whether collision coverage is included. When collision is included, the named insured must be offered protection that pays the applicable collision deductible after a qualifying collision with an uninsured motor vehicle. When collision is not included, the insurer must instead offer uninsured motorist property damage coverage.[3]
For UMPD, California law limits covered property damage to the lesser of the insured vehicle’s actual cash value or $3,500. The statutory definition does not include compensation for loss of use.[3]
These property-damage protections are offered coverage rather than protection every driver is required to purchase. California law permits a named insured to elect not to accept the coverage provided under §11580.26.[3]
California’s Current Liability and UM/UIM Limits
California’s current minimum liability requirements for a standard auto policy are $30,000 for injury or death to one person, $60,000 for injury or death to more than one person, and $15,000 for property damage.[4]
For a complete overview of required auto coverage in the state, see our California car insurance requirements guide.
For uninsured motorist bodily injury coverage, California Insurance Code §11580.2 provides that UM coverage is offered with limits equal to the bodily injury liability limits of the underlying policy. However, an insurer is not required under that provision to offer UM limits above $30,000 per person and $60,000 per accident, although higher limits may be offered.[1]
California law also allows certain written coverage elections. As a result, a policy with liability limits above 30/60 does not necessarily have identical UM/UIM limits. Review the declarations page and any written UM election rather than assuming the limits automatically match.
Check Your Actual UM/UIM Limits
Your liability limits, UM/UIM bodily injury limits, collision coverage, deductible, and property-damage selections are separate policy details. Check each one before deciding whether your current protection is appropriate.
Understanding policy limits is essential when choosing protection. Learn more in our auto insurance coverage limits guide.
How Underinsured Motorist Coverage Works in California
California UIM coverage applies when bodily injury is caused by an insured motor vehicle whose applicable liability insurance is lower than the uninsured motorist limits carried on the injured person’s vehicle.[1]
Before UIM coverage applies, the bodily injury liability limits available from all insured vehicles causing the injury generally must be exhausted through judgments or settlements, and proof of payment must be submitted to the UIM insurer.[1]
California also provides that the UIM insurer’s maximum liability cannot exceed the insured’s UIM limit minus amounts paid to the insured by or on behalf of people or organizations that may be legally responsible for the injury.[1]
In other words, UIM should not be understood as simply adding the entire UIM limit on top of whatever the responsible driver’s insurer already paid.
At-Fault Coverage
Determine how much bodily injury liability insurance is actually available from the vehicle or vehicles responsible for the injury.
Your UM/UIM Limit
Review the applicable bodily injury limit shown on your own policy and any written coverage election.
Applicable Rules
UIM recovery depends on liability, damages, exhaustion of other coverage, applicable credits, policy terms, and California law.
Can Bundling Lower the Cost of a Policy With UM/UIM Coverage?
Possibly, but the discount is not normally a separate discount for uninsured motorist coverage itself. Insurance bundling generally means buying two or more policies—such as auto and homeowners or auto and renters—from the same insurer. An insurer may then apply a multi-policy discount to one or more of those policies.
If your auto policy includes UM/UIM coverage, a multi-policy discount may reduce the overall auto premium depending on the insurer’s rules. That does not mean the UM/UIM coverage has been separately “bundled” or discounted.
Compare the total cost, not the advertised bundle percentage
Compare the bundled cost of all policies with the total cost of buying equivalent coverage separately. A bundle discount does not guarantee that one insurer will produce the lowest combined price.
What Can California UMBI Protect?
UMBI is bodily injury protection rather than coverage for damage to your vehicle. California law defines bodily injury to include resulting sickness or disease and death resulting from the injury, sickness, or disease.[1]
The California Department of Insurance describes UMBI as coverage that pays for injuries to you and people in your vehicle when an uninsured at-fault driver causes an accident.[2]
The statutory definition of an insured can extend beyond the named insured in qualifying circumstances. When the named insured is an individual, §11580.2 includes the named insured, the named insured’s spouse, certain resident relatives, and people occupying an insured motor vehicle, among others described by the statute.[1]
The amount recoverable after a particular accident is not automatic. Fault, legally recoverable damages, policy limits, policy terms, exclusions, offsets, and other provisions can affect a claim.
How California UMPD Works
Uninsured motorist property damage addresses damage to the insured vehicle rather than bodily injury. When the policy does not include collision coverage, §11580.26 requires the insurer to offer UMPD for qualifying damage caused by an uninsured motor vehicle.[3]
The amount covered is limited to the lesser of the vehicle’s actual cash value or $3,500, and personal property inside the vehicle is not part of this statutory protection.[3]
California property-damage protection also has identification and contact requirements. Payment is made only when there is actual, direct physical contact involving the insured and uninsured motor vehicles and the owner or operator of the uninsured vehicle is identified, or the uninsured vehicle is identified by its license number.[3]
Property-Damage Claims Have Their Own Deadlines
For protection under §11580.26, the accident must generally be reported to the insurer or its agent within 10 business days. If the insured and insurer disagree and arbitration is required, the statute also requires arbitration to have been formally instituted within one year from the accident for the determination described by the statute.[3]
If you already carry collision coverage, the relevant California property-damage protection is generally the offered collision deductible waiver rather than the UMPD structure used when collision is absent.
For additional information about physical-damage protection, see our guide to comprehensive car insurance coverage.
What Is a California Collision Deductible Waiver?
When a California motor vehicle liability policy includes collision coverage, §11580.26 requires the named insured to be offered protection under which the insurer pays the applicable collision deductible after a qualifying collision involving the insured vehicle and an uninsured motor vehicle.[3]
The California Department of Insurance describes collision deductible waiver coverage as paying your collision deductible when your insured vehicle is damaged in an accident with an uninsured driver who is at fault.[2]
This is different from simply choosing a lower collision deductible. Your normal deductible affects what you retain after many collision losses, while the waiver addresses qualifying uninsured-motorist circumstances.
A lower deductible may reduce your out-of-pocket cost after a collision, but it can also increase the premium. Understanding how deductible changes affect insurance costs can help drivers decide whether the savings are worth the added claim responsibility.
Can California UM Coverage Apply to a Hit-and-Run Accident?
Potentially, but bodily injury claims involving an unknown owner or operator are subject to specific statutory conditions.
Under §11580.2, when the owner or operator is unknown, bodily injury must arise from physical contact between the unknown automobile and the insured or the automobile occupied by the insured.[1]
The statute also requires the accident to be reported within 24 hours to the appropriate police department, county sheriff, or California Highway Patrol office, depending on where the accident occurred. A supporting sworn statement must then be filed with the insurer within 30 days after the accident.[1]
Hit-and-Run UM Claims Can Have Short Reporting Requirements
If another vehicle leaves the scene, report the accident promptly and review the policy’s claim requirements. California’s bodily injury UM statute contains specific conditions for claims involving an unknown driver, and individual facts can materially affect coverage.
Property-damage treatment is different. The identification requirements under §11580.26 require either identification of the owner or operator or identification of the uninsured vehicle by its license number, along with actual, direct physical contact.[3]
California UM Bodily Injury Claims Have Important Time Limits
California Insurance Code §11580.2 contains a two-year requirement for certain uninsured motorist claims. Within two years from the date of the accident, one of three statutory actions generally must occur: a bodily injury lawsuit must be filed against the uninsured motorist, an agreement must be reached regarding the amount due under the policy, or arbitration proceedings must be formally instituted through the statutory written-notice procedure.[1]
Because bodily injury hit-and-run claims and property-damage claims can also involve shorter reporting requirements, drivers should report accidents promptly, preserve relevant documents, follow their policy requirements, and obtain appropriate professional advice when a serious or disputed claim is involved.
Can California UM Coverage Be Stacked Across Vehicles or Policies?
California generally prevents UM limits from multiple vehicles or policies from being added together to create a larger available limit. Insurance Code §11580.2 provides that, regardless of the number of vehicles, covered people, claims, policies, or premiums, the limits for multiple vehicles or policies cannot be added, combined, or stacked to determine the insurance limit available to injured persons.[1]
This makes the actual UM/UIM limit selected on your policy important even when a household insures several vehicles.
How Much Does California Uninsured Motorist Coverage Cost?
There is no single statewide UM/UIM price that applies to every California driver. Your premium depends on the insurer, coverage limits, policy structure, vehicle and driver information, and other rating factors applicable to the policy.
Instead of relying on a generic citywide or statewide estimate, request actual quotes using the same liability limits, UM/UIM selections, vehicle information, drivers, collision coverage, and deductibles.
A quote that rejects UM/UIM or selects materially different limits should not be compared with a quote that includes broader UM/UIM protection as though the policies were identical.
If the amount required to start a policy is also important to you, our guide to low-upfront full coverage car insurance explains the difference between initial payments, installments, deductibles, and total policy cost.
There Is No Single Cheapest California Insurer for UM Coverage
Insurance premiums can vary from one company to another, so the California Department of Insurance recommends obtaining several quotes and comparing both costs and coverage.[2]
Drivers comparing coverage options can also review our California auto insurance quote comparison guide before selecting a policy.
For that reason, it is more useful to compare actual quotes for your driver and vehicle profile than to rank insurers using unsupported standalone UM prices.
Keep UM Quotes Comparable
Make sure a lower premium is not simply the result of lower coverage.
- ✓Match liability limitsCompare policies using the same bodily injury and property damage liability limits.
- ✓Match UM/UIM limitsVerify whether each quote includes, reduces, or rejects UM/UIM protection.
- ✓Match collision coverageCollision coverage affects which California uninsured-motorist property-damage protection is relevant.
- ✓Match deductiblesKeep collision and comprehensive deductibles consistent.
- ✓Match drivers and vehiclesUse the same household, vehicle, usage, mileage, and driver information.
- ✓Review written electionsUnderstand any UM rejection, lower-limit election, or property-damage election before accepting the policy.
Should You Keep or Reject California Uninsured Motorist Coverage?
There is no single choice that is appropriate for every California driver. The decision involves the amount of financial risk you are willing to retain, your current insurance protection, and the premium difference between the available options.
| Question to Consider | Why It Matters |
|---|---|
| What are your UM/UIM bodily injury limits? | These limits affect the maximum protection available for qualifying bodily injury claims, subject to applicable policy and statutory provisions. |
| Could you absorb a serious uninsured-driver injury loss? | Consider the financial effect of medical expenses, lost income, and other legally recoverable bodily injury damages. |
| Do you carry collision coverage? | This affects whether UMPD or collision deductible waiver protection is relevant. |
| What is your collision deductible? | A deductible waiver can have greater practical value when your normal collision deductible would be difficult to pay. |
| What UM election are you being asked to sign? | A written rejection or other permitted election can materially change the protection included in your policy. |
| What is the actual premium difference? | Compare your insurer’s real quote rather than relying on generic estimates. |

Frequently Asked Questions
Is uninsured motorist coverage required in California?
California law generally requires qualifying bodily injury liability policies to contain uninsured motorist protection, but the named insured may make a permitted written agreement to delete or modify the coverage. For that reason, a California policy can legally exist without UM coverage when the applicable statutory requirements have been satisfied.
What is the difference between uninsured and underinsured motorist coverage?
An uninsured motor vehicle has no applicable bodily injury liability insurance or meets another uninsured category defined by California law. An underinsured motor vehicle is insured, but its applicable insurance amount is lower than the uninsured motorist limits carried on the injured person’s vehicle.
What does UMBI cover in California?
UMBI addresses qualifying bodily injury or wrongful death damages an insured is legally entitled to recover from an uninsured motorist, subject to policy limits, exclusions, applicable credits, and California law.
How much does California UMPD pay?
Under California Insurance Code §11580.26, the statutory UMPD amount is limited to the lesser of the insured vehicle’s actual cash value or $3,500. It does not include compensation for loss of use.
Do I need UMPD if I already have collision coverage?
California treats the situations differently. When collision coverage is included, the insurer must offer qualifying collision deductible waiver protection. When collision is not included, the insurer must offer UMPD, unless the applicable coverage has been declined as permitted by law.
Can uninsured motorist coverage apply after a hit-and-run?
UM bodily injury coverage can potentially apply when the other vehicle’s owner or operator is unknown, but California law imposes specific conditions. These include physical contact and short reporting requirements, including a report to the appropriate law-enforcement authority within 24 hours and a sworn statement to the insurer within 30 days.
Does California UMPD cover an unidentified hit-and-run vehicle?
California property-damage protection under §11580.26 requires actual, direct physical contact and identification of the uninsured vehicle’s owner or operator, or identification of the uninsured vehicle by its license number. A completely unidentified vehicle generally will not satisfy those statutory identification requirements.
How quickly must I report a California UMPD claim?
Section 11580.26 generally requires the accident to be reported to the insurer or its agent within 10 business days. If arbitration becomes necessary, the statute also contains a one-year requirement for formally instituting arbitration.
Can I reject uninsured motorist coverage in California?
Yes. California law permits a named insured and insurer to enter into certain written agreements that delete or modify uninsured motorist protection. Review the effect of any document carefully before signing it.
Can I reject UMPD or collision deductible waiver coverage?
Yes. California Insurance Code §11580.26 permits a named insured to elect not to accept the property-damage coverage offered under that section.
Can I stack UM limits from several California vehicles or policies?
California law generally prevents UM limits from multiple vehicles or policies from being added together to create a larger available insurance limit for an injured person.
How long do I have to pursue a California uninsured motorist bodily injury claim?
California Insurance Code §11580.2 contains specific time requirements. For certain UM bodily injury claims, one of several statutory actions generally must occur within two years of the accident. Hit-and-run and property-damage claims can also involve shorter reporting requirements, so claims should be reported promptly.
Conclusion
California uninsured motorist coverage is more nuanced than a single optional line on an auto policy. UMBI addresses qualifying bodily injury caused by an uninsured motorist, UIM can apply when the responsible vehicle’s applicable bodily injury liability limits are lower than your UM/UIM limits, and California uses separate rules for vehicle damage through UMPD or collision deductible waiver protection.
Before accepting, reducing, or rejecting the coverage, review your actual UM/UIM limits, liability limits, collision coverage, deductible, property-damage selections, written elections, and premium difference. If an accident occurs—especially a hit-and-run—report it promptly because California law contains specific claim conditions and deadlines.
