Uninsured Driver Car Accident Claims in Los Angeles

By Payam Soliemanzadeh, Founder and President

Key takeaways

• UM/UIM coverage protects you when an at-fault driver lacks insurance or adequate limits in Los Angeles crashes.
• Stanley Mosk Courthouse at 111 North Hill Street hears lawsuits arising from denied or underpaid UM/UIM claims.
• You have two years under CCP §335.1 to sue; six months under Gov. Code §911.2 for government claims.
• California's January 2025 minimum of 30/60/15 still leaves many drivers underinsured on Wilshire Boulevard and the 405.

Los Angeles freeways—the 405, the 10, the 101, the 110, and the 5—carry millions of vehicles daily, and collisions on Figueroa Street, Olympic Boulevard, and Wilshire Boulevard remain frequent. Despite California's financial responsibility laws, a significant fraction of drivers operate without insurance or carry only the state minimum. When one of those drivers causes your injuries, the path to compensation shifts from their policy to your own.

Understanding uninsured and underinsured motorist coverage is not abstract legal theory in Los Angeles; it is practical financial protection. Even after the January 2025 increase in minimum liability to 30/60/15, serious injuries routinely generate medical bills that exceed $30,000 per person. Your UM/UIM policy bridges that gap when the at-fault driver cannot.

What uninsured and underinsured motorist coverage does

Uninsured motorist (UM) coverage responds when the at-fault driver has no insurance at all or flees the scene in a hit-and-run. Underinsured motorist (UIM) coverage applies when the other driver carries liability insurance, but their policy limits are insufficient to cover your damages. Both coverages pay medical expenses, lost wages, and pain and suffering just as the at-fault driver's liability policy would, but the funds come from your own insurer.

California Vehicle Code §16056 mandates that every insurer offer UM/UIM coverage equal to your liability limits. You may decline it only by signing a written waiver. If you never signed that waiver, your policy includes the coverage automatically. Insurers occasionally claim a waiver exists; obtaining your complete underwriting file early in the claim establishes the truth and protects your rights under the policy.

Filing a UM/UIM claim after a Los Angeles collision

After a crash on the 110 or at Wilshire and Figueroa, confirm the other driver's insurance status by requesting their information under Vehicle Code §16025 and checking with your insurer. File an SR-1 report with the DMV within 10 days if the collision caused injury, death, or property damage over $1,000, as required by Vehicle Code §16000. Your insurer will investigate liability and damages, often requesting medical records, wage statements, and a recorded statement from you.

UM/UIM claims involve arbitration clauses in many policies, meaning disputes over value go to binding or non-binding arbitration rather than immediate litigation. Review your policy's arbitration provision carefully. If your insurer denies coverage or offers far less than your documented losses, you may file suit in Los Angeles County Superior Court, Central District, where Los Angeles car accident cases are heard, or proceed to arbitration depending on your policy terms and strategic considerations.

Stacking, offsets, and the interplay of coverages

California does not permit stacking of UM/UIM coverage across multiple vehicles you own; your recovery is capped at the highest per-person limit on any one policy. If the at-fault driver does carry some liability insurance, that amount is credited against your UIM claim, so you recover only the difference between their limit and your UIM limit. For example, if your injuries total $100,000, the at-fault driver carries $30,000, and you have $100,000 in UIM, your UIM carrier pays $70,000 after the at-fault policy exhausts.

Medical payments (MedPay) and personal injury protection (PIP) may also apply, reimbursing bills as they accrue. Some UM/UIM policies include reimbursement or subrogation clauses that require you to repay MedPay advances from any UM/UIM settlement. Read your declarations page and policy contract; understanding the sequence and offsets avoids surprises during negotiation and preserves the maximum net recovery available under your combined coverages.

Local details

If litigation becomes necessary, you will file in the Stanley Mosk Courthouse at 111 North Hill Street, Los Angeles, CA 90012, which serves the Central District of the Los Angeles County Superior Court. The courthouse hears both suits against at-fault drivers and actions against your own UM/UIM carrier for breach of contract or bad faith. Serious collisions on Interstate 5, Interstate 10, U.S. 101, Interstate 110, or Interstate 405 often result in treatment at Los Angeles General Medical Center, a Level I trauma center at 2051 Marengo Street, Los Angeles, CA 90033. Emergency-room records and trauma-surgery documentation from that facility carry substantial weight in establishing the severity of your injuries and the reasonableness of your claimed damages. You must file personal injury claims within two years of the collision under CCP §335.1, and if a government vehicle was involved, you have only six months to submit an administrative claim under Government Code §911.2 before any lawsuit is permitted.

Frequently Asked Questions

What happens if I have no UM/UIM coverage?

If you carry no UM/UIM coverage and the at-fault driver is uninsured or underinsured, your recovery is limited to what that driver can pay personally. Judgments against uninsured defendants are often uncollectible. Wage garnishment and asset liens are available, but many uninsured drivers lack attachable income or property, leaving you with a paper judgment and no practical recovery.

Does UM/UIM cover passengers and pedestrians?

Yes. UM/UIM coverage extends to passengers in your vehicle and, under many policies, to you when you are a pedestrian or bicyclist struck by an uninsured driver. The policy language governs; review the definitions of "insured person" in your declarations. Pedestrian collisions on Wilshire Boulevard or Olympic Boulevard trigger the same UM coverage as vehicle-occupant injuries if the striking driver lacked adequate insurance.

Can my insurer raise my rates for filing a UM/UIM claim?

California Insurance Code §1861.02(a) prohibits surcharges for claims where you are not at fault. A UM/UIM claim arises from another driver's negligence, so your premium should not increase solely because you filed. Insurers may non-renew your policy for other reasons, but a rate hike based exclusively on a not-at-fault UM/UIM claim violates state law and is grounds for a Department of Insurance complaint.

How long does a UM/UIM claim take?

Timeline depends on injury severity, policy limits, and whether arbitration or litigation is required. Simple soft-tissue claims may resolve in months; catastrophic injuries involving surgeries, ongoing treatment, and disputed liability can take one to two years. Starting early preserves evidence, and consulting a car accident attorney before accepting an initial offer ensures you do not waive rights or settle below policy limits prematurely.
