California UM/UIM, Property Damage and Claim Preservation

California UM/UIM, Property Damage and Claim Preservation

Part C: Uninsured Motorists (UM) & Underinsured Motorists (UIM) Coverage

UM protects insured persons legally entitled to recover bodily-injury damages from an uninsured motorist. UIM addresses the specified underinsured-vehicle trigger. Insured status, fault, damages, limits, exclusions and statutory procedures all matter; owning an insured vehicle does not prove every claimant qualifies.

Required coverage and written rejection

CIC § 11580.2 requires UM coverage unless deleted through the statutory written agreement. Subdivision (m) requires the offer to equal underlying bodily-injury limits but does not require offering above $30,000 per person/
$60,000 per accident. Higher UM limits may be purchased. The 2026 ordinary minimum is also 30/60, so a liability limit of 100/300 does not automatically create 100/300 UM. A permitted written deletion or exclusion agreement uses the statutory form and binds the insured persons as the statute provides. UIM is offered with UM as a single coverage; its limits match UM unless greater limits are offered under the statute.

Uninsured vehicle and hit-and-run

An uninsured vehicle can include one without applicable bodily-injury insurance or bond, a qualifying denial/insolvency situation, a vehicle below the financial-responsibility requirement, or an unidentified vehicle meeting statutory conditions. Certain owned, government, self-insured and other vehicles are excluded from the definition. For unidentified hit-and-run bodily-injury claims, the statutory conditions include physical contact, reporting to the appropriate law-enforcement agency within 24 hours and a statement under oath to the insurer within 30 days thereafter. Indirect-contact cases need the actual legal analysis; do not call every no-contact avoidance crash a qualifying UM accident.

Underinsured trigger, exhaustion and offsets

Under § 11580.2(p), the responsible vehicle's applicable bodily-injury limit must be less than the injured insured's UM/UIM limit. If both are $100,000, UIM is not triggered merely because damages exceed $100,000. The applicable bodily-injury liability limits of all insured vehicles causing injury must be exhausted by judgments or settlements, with proof submitted to the UIM insurer, before UIM applies.

California uses a reduction/offset approach. With $100,000 UIM, $130,000 damages and $30,000 liability payment from the responsible driver, the maximum UIM payment in the simplified example is $70,000. Total recovery is $100,000, not $130,000. Lower proven damages or other authorized offsets can reduce payment further. UIM is not simply an extra $100,000 on top of every tort payment.

Limits, anti-stacking and arbitration

The statute restricts combining applicable UM limits. Multiple vehicles on one policy do not multiply a per-person limit; multiple policies do not create unrestricted stacked recovery. Read the applicable statutory anti-stacking and other-insurance provisions, and identify the claimant's highest applicable protection rather than adding every declarations figure. Statutory UM arbitration addresses whether the insured is legally entitled to recover and the amount; preserving a claim requires the specified timely action, not simply an informal request to an adjuster.

Property damage and collision-deductible waiver

Uninsured-motorist property damage and a collision-deductible waiver are separate options. California UMPD generally has a $3,500 limit and requires an identified uninsured responsible vehicle; it is not hit-and-run bodily-injury coverage transferred to property. When collision coverage applies, a purchased collision-deductible waiver can waive the deductible for a qualifying identified uninsured-motorist loss. A vehicle owner should not expect both unlimited UMPD and collision benefits for the same damage. Identify purchased coverage, fault and verification of uninsured status.

The adjuster should document the rejection/election form, applicable limits, insurer insolvency or denial evidence, liability payments and the separate value of injury damages. Those documents prevent confusing a mandatory offer rule with an automatically selected higher limit. Sources: CDI automobile guide and CIC § 11580.2.

Preserving statutory rights

For the UM bodily-injury cause of action under § 11580.2(i), preservation ordinarily requires action within two years: suit against the uninsured motorist, agreement on the amount, or formal institution of arbitration by written notice sent by certified mail, return receipt requested, to the insurer or its filed agent. Merely telling an adjuster that an injury exists is not one of these statutory acts. Arbitration ordinarily must conclude within five years of institution, or three years after conclusion of a qualifying workers compensation claim, whichever is later; written extensions and recognized equitable excuses can matter. Subdivision (p)'s UIM terms prevail over conflicting subdivisions, so do not indiscriminately apply every UM deadline to UIM without analyzing that provision.

Section 11580.26 separately requires the specified offer of collision-deductible protection where collision exists, or UMPD where it does not, subject to its exclusions and permitted election. UMPD is limited to the lesser of vehicle ACV or $3,500, excluding personal contents and loss of use. Both specified coverages require actual direct contact and identification of the owner/operator or vehicle license number. Report to the insurer/agent within ten business days; a disputed entitlement requires the specified formal arbitration within one year. These are not the unidentified-hit-and-run bodily-injury 24-hour police and 30-day sworn-statement rules. An unrepresented pending claimant receives the statute's 30-day limitations notice, with its stated tolling consequence for failure.

For example, an identified uninsured driver damages a $9,000 car by $5,000. Without collision, purchased qualifying UMPD cannot pay more than $3,500. With collision and the purchased deductible-waiver coverage, analyze collision payment and waiver of its deductible; do not add a duplicate $3,500 payment to full collision recovery. The facts, chosen coverage and statutory conditions govern the result.
