Hit by an Uninsured Driver in Los Angeles? How California UM/UIM Coverage Protects You
Article Summary: Los Angeles has one of the highest uninsured driver rates in California and the nation — an estimated 1 in 6 drivers on LA roads carries no auto insurance at all. If you are injured by an uninsured or underinsured driver, you are not without options. California law requires insurers to offer uninsured motorist (UM) and underinsured motorist (UIM) coverage, which pays your injury and damage claims when the at-fault driver cannot. UM coverage also applies to hit-and-run accidents. If you do not carry UM/UIM coverage, you may still be able to pursue the at-fault driver personally or identify other liable parties. California’s two-year statute of limitations (CCP § 335.1) applies to all personal injury claims. Attorney Steven M. Sweat of Steven M. Sweat, Personal Injury Lawyers, APC has helped Los Angeles accident victims recover compensation from uninsured and underinsured drivers for over 30 years. Free consultation: 866-966-5240.
It is one of the most devastating things an accident victim can hear: the driver who hit you has no insurance. For a moment, it can feel like your right to compensation has simply evaporated — that there is no one to pay for your medical bills, your lost wages, your totaled car, or the pain you are going to live with for months.
The reality is more complicated — and more hopeful — than that initial shock suggests. California law provides specific legal tools designed for exactly this situation. Your own auto insurance policy likely includes coverage that applies even when the other driver has nothing. And even when it doesn’t, experienced legal counsel can often find other pathways to recovery that an unrepresented victim would never identify on their own.
This guide covers everything Los Angeles accident victims need to know about uninsured and underinsured motorist accidents: the scope of the problem in LA specifically, how UM and UIM coverage works, what happens in a hit-and-run, what options exist when you have no coverage of your own, and how to protect your rights from the moment of impact forward.
Attorney Steven M. Sweat has represented Los Angeles injury victims in uninsured and underinsured motorist cases for over 30 years. What follows reflects everything he has learned navigating these claims on behalf of people who were told — incorrectly — that they had no options.
The Uninsured Driver Problem in Los Angeles
Los Angeles is not just a large city — it is a city with a structurally elevated uninsured driver problem. Several factors converge to make LA one of the highest-risk environments in the country for being hit by an uninsured motorist:
| ~16% | Estimated percentage of California drivers who carry no auto insurance — approximately 1 in 6 vehicles on the road statewide. In urban Los Angeles corridors, rates are believed to be even higher in certain areas. |
| ~29,000 | Uninsured motorist crashes reported in Los Angeles County in a recent study year, making LA one of the top counties in the U.S. for uninsured driver incidents. |
| $30,000 | California’s minimum required liability coverage per injured person — a limit so low that it is exhausted by a single emergency room visit and a few days of hospitalization, even in cases where the driver does carry insurance. |
These numbers have real consequences. If you are injured in Los Angeles and the at-fault driver is uninsured — or carries only the state minimum — you face the same medical bills, the same lost wages, and the same pain and suffering as if the driver had adequate coverage. The only thing missing is the obvious source of payment.
Understanding what California law provides in this situation — and what your own policy likely covers — is the first step toward protecting your financial recovery.
California’s Mandatory Auto Insurance Laws — and Why They Don’t Fully Protect You
California Vehicle Code § 16020 requires all drivers to maintain minimum auto insurance coverage of:
- $30,000 bodily injury liability per person
- $60,000 bodily injury liability per accident
- $15,000 property damage liability
The problem is obvious: a single moderate car accident injury — a herniated disc requiring surgery, for example — can generate $80,000 to $150,000 or more in medical expenses. A catastrophic injury can easily reach seven figures.
Even drivers who comply with California’s minimum requirements may be, in practical terms, underinsured relative to the injuries they cause. This is why underinsured motorist (UIM) coverage exists alongside uninsured motorist (UM) coverage — and why California insurance law gives accident victims specific rights to both.
| ⚠ NOTE ON CALIFORNIA’S INSURANCE MINIMUMS: As of January 1, 2025, California increased its mandatory minimums to $30,000/$60,000/$15,000. Policies issued or renewed after that date must meet the new minimums. However, millions of pre-existing policies still carry the old $15,000/$30,000/$5,000 limits. Do not assume the other driver’s coverage is adequate simply because they carry insurance. |
What Is Uninsured and Underinsured Motorist Coverage in California?
California Insurance Code § 11580.2 requires every auto insurer in California to offer uninsured motorist (UM) coverage to its policyholders. You can reject this coverage in writing, but if your policy does not reflect a written rejection, you have it. Here is what each type covers:
Uninsured Motorist Bodily Injury (UMBI) Coverage
UMBI pays for your injuries — medical expenses, lost wages, pain and suffering, and other damages — when you are hit by a driver who has no liability insurance at all. It functions as a substitute for the liability coverage the at-fault driver was supposed to carry.
UMBI also applies in hit-and-run accidents — situations where the at-fault driver fled and cannot be identified. Under California law, a hit-and-run driver is treated as an uninsured motorist for purposes of your UM claim, subject to certain conditions (discussed below).
Uninsured Motorist Property Damage (UMPD) Coverage
UMPD covers damage to your vehicle when the at-fault driver has no insurance. Unlike UMBI, UMPD typically carries a deductible (often $250). Note that UMPD does not apply to hit-and-run accidents in California — for hit-and-run vehicle damage, you would need collision coverage.
Underinsured Motorist (UIM) Coverage
UIM coverage kicks in when the at-fault driver has some insurance, but their policy limits are not enough to fully compensate you for your injuries. Your UIM coverage bridges the gap between what their policy pays and the actual value of your damages — up to your own UIM policy limits.
| Example: You suffer injuries worth $150,000. The at-fault driver carries California’s minimum $15,000 per-person liability limit. Farmers or GEICO pays their $15,000. Your own UIM coverage (if you carry $100,000 UIM) pays the next $100,000 — for a total of $115,000 recovered. The remaining $35,000 may be pursued through other avenues. Without UIM coverage, you would have recovered only $15,000 on a $150,000 injury claim. |
How Does a UM/UIM Claim Work in California?
Filing a UM or UIM claim is different in an important way from filing a liability claim against the other driver: you are filing a claim against your own insurance company. This changes the dynamic, because your insurer technically owes you a duty of good faith — but in practice, many UM/UIM claims are contested just as aggressively as third-party liability claims.
Step 1 — Report the Accident to Your Insurer
Notify your own insurance company as soon as possible after an accident involving an uninsured or hit-and-run driver. Prompt reporting is typically a policy requirement, and delays can create problems for your claim.
Step 2 — Establish the Other Driver’s Lack of Insurance
For a UM claim, you will need to demonstrate that the other driver was uninsured (or unidentified in a hit-and-run). This is typically done through the police report, DMV records, or a letter from the other driver’s non-existent insurer. Your attorney can help obtain this documentation.
Step 3 — Document Your Injuries and Damages
Your UM/UIM claim is evaluated on the same factors as any personal injury claim: medical expenses, lost wages, pain and suffering, and other damages. Thorough medical documentation, consistent treatment, and a clear record of financial losses are all essential.
Step 4 — Negotiate With Your Own Insurer
Your insurer will investigate and make a settlement offer. Like any insurer, they have financial incentives to minimize the payout — even on a UM/UIM claim against your own policy. Do not assume your insurer’s initial offer reflects the actual value of your claim.
Step 5 — Arbitration (If Required by Your Policy)
Many California auto insurance policies require that disputed UM/UIM claims go to binding arbitration rather than to court. This means your case will be decided by a neutral arbitrator instead of a jury. Arbitration can be faster than trial, but the outcome is generally final and not appealable. Experienced legal representation in UM/UIM arbitration is particularly important for this reason.
Does Uninsured Motorist Coverage Apply to Hit-and-Run Accidents in California?
Yes — with important conditions. California Insurance Code § 11580.2 extends UM bodily injury coverage to hit-and-run accidents, treating the unidentified driver as an uninsured motorist. However, California law imposes specific requirements for a hit-and-run UM claim:
- Physical contact requirement — California generally requires that the hit-and-run vehicle actually make physical contact with your vehicle or with you. A “phantom vehicle” accident — where a car cuts you off and causes you to crash without touching your car — may not trigger UM coverage under some policies.
- Police report — You must report the hit-and-run to police within a reasonable time. Most insurers require a police report as part of the UM claim.
- Report to your insurer — Notify your insurer promptly. Hit-and-run UM claims have the same prompt-reporting obligations as other UM claims.
- No UMPD for hit-and-run — As noted above, UMPD does not cover vehicle damage in hit-and-run accidents. Collision coverage applies instead.
If you were the victim of a hit-and-run in Los Angeles, file your California SR-1 form with the DMV within 10 days, report the incident to police immediately, and contact a personal injury attorney to understand your full range of options.
What If You Don’t Have UM/UIM Coverage?
Not every driver carries UM/UIM coverage — some reject it in writing, others have lapses in coverage, and some are driving vehicles owned by others. If you are injured by an uninsured driver and do not have UM/UIM coverage available, you still have potential avenues for recovery:
Pursuing the At-Fault Driver Personally
An uninsured driver is still legally liable for damages they cause. The challenge is collectability: if the driver has no assets — no real property, no significant savings or investments, no garnishable wages — a judgment against them may be uncollectable in practice. However, many people who appear judgment-proof today are not permanently so. Judgments in California can remain enforceable for years and can be renewed. An attorney can investigate the at-fault driver’s financial situation and advise whether personal pursuit is realistic.
Identifying Other Liable Parties
Depending on the circumstances, other parties may share liability for your accident:
- The vehicle owner — If the uninsured driver was operating a vehicle owned by someone else, the vehicle owner may be liable under California’s owner liability statutes (Vehicle Code § 17150)
- An employer — If the driver was operating a vehicle in the course and scope of employment, their employer may be vicariously liable regardless of insurance status
- A government entity — If dangerous road conditions contributed to the accident, a public entity may bear partial responsibility (subject to government claims procedures)
- A third party — If a commercial establishment served alcohol to the driver, California’s dram shop laws may provide additional avenues of recovery
Your Own MedPay Coverage
If your policy includes Medical Payments (MedPay) coverage, it pays your medical bills regardless of fault and regardless of whether the other driver has insurance. MedPay is a no-fault benefit — your insurer pays your medical costs up to the policy limit without requiring you to establish who caused the accident.
Health Insurance
Your own health insurance covers accident-related medical treatment regardless of the auto insurance situation. Use it for immediate and ongoing care. Note that your health insurer may have a subrogation right — meaning they may seek reimbursement from any eventual recovery. An attorney can help manage these lien claims and in many cases negotiate them down.
Your Recovery Options: A Scenario-by-Scenario Guide
| Your Situation | Primary Recovery Option | Secondary Options |
| At-fault driver is uninsured; you have UM/UIM coverage | File UM claim with your own insurer | Personal suit against driver if collectible |
| At-fault driver has state minimum limits ($15K); your injuries exceed $15K; you have UIM | Exhaust their $15K liability, then file UIM claim with your insurer | Personal suit against driver for remainder |
| Hit-and-run accident; you have UM coverage | File UM claim (physical contact required) | Police investigation; collision coverage for vehicle damage |
| Hit-and-run; no UM coverage | Collision coverage for vehicle damage only | Investigate identity of driver if possible |
| Uninsured driver; no UM/UIM coverage | Personal suit against the driver | Employer liability; vehicle owner liability; MedPay; health insurance |
| Uninsured driver; someone else owns the vehicle | Suit against both driver and vehicle owner (VEH § 17150) | UM claim if you have UM coverage |
| Driver insured but company denies claim | Pursue liability claim; consult attorney re: bad faith | UM/UIM if liability denial stands |
What to Do Immediately After Being Hit by an Uninsured Driver in Los Angeles
- Call 911 — Get a police report. For a hit-and-run, a police report is required for your UM claim. For a crash with an uninsured driver, the report documents the absence of insurance.
- Get the other driver’s information anyway — Even if they have no insurance, get their name, address, driver’s license number, vehicle description, and license plate. Photograph their license and registration if they will allow it.
- Do not let the other driver talk you out of calling police — An uninsured driver has every incentive to resolve things “privately.” Do not agree to this. Without a police report, your claim options narrow significantly.
- Seek medical attention immediately — Even if you feel fine. Delayed symptom onset is common. Gaps in medical treatment harm your claim.
- Photograph and document everything — All vehicle damage, scene conditions, license plates, and visible injuries.
- Notify your own insurer promptly — Whether you have UM coverage or not, notify your insurer of the accident as soon as possible.
- File the California SR-1 form within 10 days — The DMV filing obligation applies to uninsured driver accidents just as it does to all qualifying accidents. See our full guide to the California SR-1 form.
- Contact a personal injury attorney — Uninsured motorist claims are among the most contested and complicated in California personal injury law. An experienced Los Angeles car accident attorney can identify every available avenue of recovery and handle the claims process.
Why Your Own Insurer May Fight Your UM/UIM Claim
It is a jarring reality for many accident victims: you file a claim with your own insurance company — the company you have been paying premiums to for years — and they dispute your claim. But UM/UIM claims are frequently contested by insurers for several reasons:
- Liability disputes — Your insurer may argue that the uninsured driver was not entirely at fault, or that you share comparative fault
- Injury causation disputes — The same tactics used by Farmers and GEICO in third-party claims — disputing injury causation, requesting independent medical exams, challenging treatment necessity — apply equally in UM/UIM claims
- Coverage disputes — Your insurer may argue that a policy exclusion, late reporting, or some other coverage defense bars or limits your claim
- Arbitration strategy — If your policy requires arbitration, your insurer may use the arbitration process strategically to limit your recovery
California law does impose a duty of good faith and fair dealing on your own insurer in a UM/UIM context — meaning they cannot unreasonably deny or delay a valid claim without potential bad faith liability. But asserting those rights requires knowing what they are and having legal counsel who can enforce them.
| A personal injury attorney who handles UM/UIM claims regularly knows the difference between a legitimate coverage dispute and a bad faith denial. If your own insurer is stalling, lowballing, or denying a valid UM/UIM claim, you may have additional legal remedies beyond the underlying claim. |
Deadlines That Apply to Uninsured Motorist Claims in California
Multiple overlapping deadlines govern uninsured motorist and personal injury claims in California. Missing any one of them can permanently bar your recovery:
| Deadline | What It Covers |
| 10 days from accident | California SR-1 form filed with the DMV (Vehicle Code § 16000) |
| Prompt / as soon as practicable | Report accident to your own insurer (check your policy — many require prompt notice) |
| 1–2 years (policy-specific) | Some UM/UIM policies contain internal claim deadlines shorter than the statute of limitations — read your policy |
| 2 years from accident | California statute of limitations for personal injury claims (CCP § 335.1) |
| 6 months from incident | Claims against government entities (California Government Code § 911.2) — much shorter deadline if a public entity is involved |
| 3 years from accident | Property damage claims (CCP § 338) — separate from the personal injury deadline |
The two-year statute of limitations is the outer boundary for personal injury lawsuits, but internal policy deadlines, government claim requirements, and evidence preservation concerns all argue for acting sooner. Review our complete guide to California’s personal injury filing deadlines for full detail on how these timelines interact.
Frequently Asked Questions: Uninsured Motorist Accidents in California
| Frequently Asked Question | Answer |
| What is uninsured motorist coverage in California? | Uninsured motorist (UM) coverage is an optional-but-required-to-be-offered component of California auto insurance policies. It pays your injury and property damage claims when you are hit by a driver who has no liability insurance. California Insurance Code § 11580.2 requires insurers to offer it; you must reject it in writing for your policy to exclude it. |
| What is the difference between UM and UIM coverage? | UM (uninsured motorist) coverage applies when the at-fault driver has no insurance at all. UIM (underinsured motorist) coverage applies when the at-fault driver has some insurance, but their limits are too low to fully compensate you. Both are typically sold together as UM/UIM coverage. |
| Does uninsured motorist coverage cover hit-and-run in California? | Yes — California law treats unidentified hit-and-run drivers as uninsured motorists for purposes of UMBI coverage. Physical contact between the hit-and-run vehicle and your vehicle (or you) is generally required. UMPD does not cover hit-and-run vehicle damage — collision coverage applies instead. |
| How does underinsured motorist coverage work in California? | If you are injured by a driver whose liability limits are insufficient to cover your damages, your UIM coverage pays the gap between what their policy covers and your actual losses — up to your own UIM policy limits. You must first exhaust the at-fault driver’s liability coverage before UIM applies. |
| What does UM/UIM coverage mean? | UM/UIM coverage is the combined package of uninsured motorist and underinsured motorist protection on your auto insurance policy. It protects you when the at-fault driver either has no insurance (UM) or has inadequate insurance (UIM). |
| What is uim ca? | UIM CA refers to underinsured motorist coverage as it applies in California — the state-specific version of UIM coverage governed by California Insurance Code § 11580.2 and related regulations. |
| What is uninsured motorist bodily injury coverage in California? | UMBI (uninsured motorist bodily injury) coverage pays for your physical injuries — medical bills, lost income, pain and suffering — when caused by an uninsured driver. It is the UM component that covers personal harm, as distinct from UMPD which covers vehicle damage. |
| Can I sue an uninsured driver in California? | Yes. An uninsured driver is still civilly liable for damages they cause. The practical challenge is collectability — if the driver has no assets, a judgment may be difficult to enforce. An attorney can investigate the driver’s financial situation and advise on whether personal pursuit is viable. |
| What if I rejected UM/UIM coverage and now I need it? | If you signed a written rejection of UM/UIM coverage, that rejection is binding for your policy term. You cannot retroactively add UM/UIM coverage after an accident. Going forward, your attorney can identify other recovery options including personal suit against the driver, employer liability, or other third-party claims. |
| How long do I have to file a UM/UIM claim in California? | The general personal injury statute of limitations is two years (CCP § 335.1), but your own policy may contain internal deadlines shorter than this. Additionally, claims against government entities have a six-month deadline. Review your policy and consult an attorney as soon as possible. |
