What to Do When the At-Fault Driver Has No Insurance in California

California has one of the highest uninsured-driver rates in the country. The Insurance Research Council's most recent estimates place roughly 17% of California drivers on the road without coverage — meaning nearly one in six collisions involves an at-fault party with no liability policy to pay your claim. Your recovery still exists, but it routes through different sources, on different timelines, with different rules.

The first source of recovery is almost always your own uninsured motorist (UM) coverage. California Insurance Code § 11580.2 requires every auto liability policy issued in the state to offer UM/UIM coverage, and the carrier cannot remove it without your written waiver. If you never signed a waiver, you have it — at minimum at the statutory floor of 15/30 (bodily injury) and 3,500 (property damage). Many drivers carry it at higher limits and do not realize the coverage exists until an uninsured driver hits them.

UM coverage functions as a stand-in for the missing liability policy. Your own carrier essentially steps into the at-fault driver's shoes — you prove fault and damages exactly as you would against a liability insurer, and your UM carrier pays up to your policy limits. Critically, using UM coverage cannot lawfully be used to raise your premiums or non-renew your policy in California; Insurance Code § 491 prohibits adverse action for not-at-fault claims.

UM claims are adversarial despite being against your own carrier. The same adjuster tactics described in our adjuster-tactics article apply — recorded statements, blanket medical authorizations, lowball offers, surveillance, and social media monitoring. Your own carrier owes you a duty of good faith under Egan v. Mutual of Omaha (1979) 24 Cal.3d 809, but their financial incentive is identical to any liability carrier: minimize the payout. Treat the UM adjuster the same way you would treat the adverse adjuster.

Uninsured motorist disputes resolve through contractual arbitration, not court. Insurance Code § 11580.2(f) requires UM disputes over liability or damages to be submitted to a single neutral arbitrator. This is faster than litigation, has no jury, and the arbitrator's award is final and binding up to policy limits. Strategy in UM cases is built around this forum — the demand package, the medical proof, and the expert work all need to be arbitration-ready from the start.

Recovery sources beyond UM coverage

Several recovery sources are routinely overlooked. Medical Payments (MedPay) coverage on your own policy pays medical expenses regardless of fault, typically $1,000–$10,000, with no deductible and no reimbursement obligation when the case settles (in most California policies). If the uninsured driver was working at the time of the crash — driving for a delivery service, a contractor, a real estate company, or any commercial purpose — their employer's commercial auto or general liability policy may apply under respondeat superior. If the crash involved a defective vehicle component, a product liability claim against the manufacturer is independent of the driver's insurance status. If a third party negligently entrusted the vehicle (an owner who loaned a car to an unlicensed or impaired driver), that owner's policy may respond.

Suing the uninsured driver personally

An uninsured driver remains personally liable for the damages they caused. A judgment can be enforced against wages, bank accounts, non-exempt real property, and in some cases a driver's license suspension under Vehicle Code § 16070 (the state suspends the license of any uninsured driver found liable for an unsatisfied judgment exceeding the statutory minimums until the judgment is paid or a satisfactory settlement is reached). Practically, collection from an uninsured driver is often limited by asset exemptions and judgment-proof status, but the license-suspension mechanism creates meaningful settlement pressure and many cases do produce real recovery.

Proposition 213 and the insurance requirement

California Civil Code § 3333.4 (Proposition 213) bars uninsured drivers from recovering non-economic damages (pain and suffering, emotional distress, loss of enjoyment) in their own injury claim, even when the other driver is 100% at fault. Economic damages — medical bills, wage loss, property damage — remain recoverable. If you were the uninsured driver at the time of the crash, Prop 213 does not eliminate your case, but it dramatically reduces its value and changes the demand strategy entirely. Confirm your insurance status as of the date of loss before any settlement discussion.

• Uninsured motorist (UM) coverage is required to be offered on every California policy — you have it unless you signed a written waiver.
• Statutory minimum UM limits are 15/30 bodily injury and $3,500 property damage; many policies carry materially more.
• Using UM coverage cannot lawfully raise your premiums (Insurance Code § 491).
• UM disputes go to single-arbitrator binding arbitration under Insurance Code § 11580.2(f), not a jury trial.
• MedPay pays medical expenses regardless of fault and stacks on top of UM recovery.
• An unsatisfied judgment against an uninsured driver triggers license suspension under Veh. Code § 16070.

Your own carrier is adverse on UM claims The friendly tone of your 'own' company evaporates the moment you make a first-party UM claim. The adjuster handling your file has the same metrics, the same software-driven reserve, and the same duty to minimize payout as any third-party adjuster. Build the file as if you are headed to arbitration from day one — because under Insurance Code § 11580.2(f), you are.

Frequently Asked Questions

Q: What if the driver who hit me has no insurance? A: Your first source of recovery is your own uninsured motorist (UM) coverage under Insurance Code § 11580.2. Your carrier stands in for the missing liability policy and pays up to your UM limits. You should also check MedPay (medical regardless of fault), the driver's employer (if they were working), the vehicle owner (if different from the driver), and a personal claim against the driver themselves. Speak with an attorney before recording any statement or signing any authorization — even with your own carrier.

Q: How do I know if I have uninsured motorist coverage in California? A: Check your policy declarations page for 'UM' or 'Uninsured Motorist' coverage and a corresponding limit (e.g., '25/50' or '100/300'). Every California auto policy must offer UM coverage under Insurance Code § 11580.2 and the coverage is automatically included unless you signed a written waiver. If you have no written waiver on file with the carrier, you have UM coverage even if the declarations page does not clearly show it — request a coverage verification letter in writing.

Q: What is the difference between UM and UIM coverage? A: Uninsured motorist (UM) coverage applies when the at-fault driver has no liability insurance at all (or cannot be identified, as in a hit-and-run). Underinsured motorist (UIM) coverage applies when the at-fault driver has insurance but at limits insufficient to cover your damages. In California, UIM coverage 'fills the gap' only between the at-fault driver's limits and your own UIM limit — not above your UIM limit. If you carry $100,000 UIM and the at-fault driver carries $25,000, your UIM exposure is $75,000.

Q: Will making an uninsured motorist claim raise my insurance rates? A: No. California Insurance Code § 491 and 10 CCR § 2632.5 prohibit carriers from raising rates, surcharging, or non-renewing a policy based on a not-at-fault claim — including a UM claim where another driver caused the crash. If your carrier attempts to raise rates after a UM claim, that is potentially an unfair claims practice under Insurance Code § 790.03 and should be reported to the California Department of Insurance.

Q: Can I sue an uninsured driver personally in California? A: Yes. An uninsured driver remains personally liable in tort for the damages they caused. A civil judgment can be enforced against wages, bank accounts, and non-exempt property, and under Vehicle Code § 16070 the state will suspend the driver's license until the judgment is satisfied or a settlement reached. Collection realities vary — many uninsured drivers are judgment-proof — but the license-suspension lever creates real settlement pressure and many cases do produce meaningful recovery.

Q: What happens if I was the uninsured driver when the accident happened? A: California Civil Code § 3333.4 (Proposition 213) bars an uninsured driver from recovering non-economic damages (pain and suffering, emotional distress) even when the other driver is 100% at fault. You can still recover economic damages — medical bills, lost wages, property damage — but the most valuable part of most injury claims is eliminated. Limited exceptions exist (the other driver was DUI, the uninsured driver was a passenger, the vehicle was an employer's). Speak with an attorney immediately about your specific facts.

Q: How long do I have to file an uninsured motorist claim in California? A: Two separate clocks apply. The underlying tort statute of limitations is two years from the date of injury under Code of Civil Procedure § 335.1 — the deadline to sue the uninsured driver personally. The UM claim against your own carrier is contractual and governed by Insurance Code § 11580.2(i), which requires you to either (a) file suit against the uninsured motorist, (b) agree in writing with your insurer to arbitrate, or (c) formally demand arbitration in writing within two years of the date of loss. Missing the UM-specific deadline forfeits the coverage even when the tort claim is still timely.

Q: What is a hit-and-run claim and is it covered by UM? A: Yes, in California a hit-and-run is treated as an uninsured-motorist claim under Insurance Code § 11580.2(b). Coverage applies when the at-fault driver cannot be identified. Two strict proof requirements apply: (1) actual physical contact between the vehicles (the 'phantom vehicle' rule — a driver who runs you off the road without contact is generally not covered), and (2) the incident must be reported to the police within 24 hours and to the insurer within 30 days. Document the contact with photos of vehicle damage immediately.

Q: Should I get an attorney for an uninsured motorist claim? A: In almost every case, yes. UM claims are adversarial despite being against your own carrier — the same tactics, the same software-driven reserves, the same incentive to minimize payout apply. Disputes resolve in binding arbitration under Insurance Code § 11580.2(f) where the carrier will be represented by experienced defense counsel; an unrepresented claimant is at a structural disadvantage. The Insurance Research Council's data showing represented claimants net roughly 3.5x more applies equally to UM claims.
