Getting hit by a driver who has no insurance is one of the most frustrating situations on the road, and unfortunately, it is not rare. California has one of the highest rates of uninsured drivers in the country. If you’ve been seriously hurt in an uninsured driver accident in California, you may still have meaningful options for compensation, even when the at-fault driver has nothing to offer.

This guide explains how uninsured motorist coverage works in California, what catastrophic injury victims should know about stacking and policy limits, and how recent rideshare insurance changes under Senate Bill 371 affect Uber and Lyft passengers starting January 1, 2026.

How Common Are Uninsured Drivers in California?

Industry studies consistently estimate that roughly one in six California drivers is uninsured. In some Southern California neighborhoods, the rate runs even higher. When a serious crash involves an uninsured driver, injured people often discover that suing the driver personally is futile, because there are simply no assets to recover.

This is where uninsured motorist (UM) and underinsured motorist (UIM) coverage becomes critical, and where many people are surprised to learn what their own policy can do for them.

Understanding Uninsured and Underinsured Motorist Coverage

California requires insurers to offer UM/UIM coverage, but drivers can reject it in writing. If you accepted the coverage, it can be a powerful safety net.

Uninsured Motorist (UM) Coverage

UM coverage applies when:

  • The at-fault driver has no insurance
  • The at-fault driver cannot be identified (hit-and-run with physical contact)
  • The at-fault driver’s policy is invalid or denied

Underinsured Motorist (UIM) Coverage

UIM coverage applies when:

  • The at-fault driver has insurance, but not enough to cover your damages
  • Your UIM limits are higher than the at-fault driver’s liability limits

In a typical California UIM claim, your insurer pays the difference between the at-fault driver’s policy limits and your UIM limits. For example, if the at-fault driver carries the state minimum and your UIM coverage is $250,000, you may recover up to the gap between the two.

California’s New Minimum Liability Limits

California minimum liability limits increased effective January 1, 2025, to $30,000 per person, $60,000 per accident, and $15,000 for property damage. While this is an improvement over the prior limits, it is still nowhere near enough to cover catastrophic injuries.

Why UM/UIM Coverage Matters Most in Catastrophic Injury Cases

When injuries are severe, the gap between what the at-fault driver’s insurance covers and what an injured person actually needs can be enormous. Consider what catastrophic injury victims often face:

  • Traumatic brain injuries with lifetime care needs
  • Spinal cord injuries requiring home modifications and assistive equipment
  • Amputations requiring prosthetics, replacements, and rehabilitation
  • Severe burns requiring multiple surgeries
  • Permanent loss of earning capacity

A $30,000 liability policy will not begin to cover any of these injuries. A robust UM/UIM policy can mean the difference between financial stability and financial devastation.

Legal Strategies for Finding Additional Coverage

A thorough investigation often uncovers coverage that injured people did not know they had. Sources that may apply include:

  • Stacked household policies if multiple vehicles are covered under separate policies (subject to policy language)
  • Umbrella policies that may extend UM/UIM coverage
  • Employer-owned vehicle coverage if the at-fault driver was working
  • Commercial policies if the at-fault vehicle was being used for business
  • Rideshare policies during active driving periods
  • Vehicle owner liability when the driver was not the registered owner
  • Negligent entrustment claims against the owner who allowed an unsafe driver to use the vehicle

Identifying every available source of coverage requires reviewing every policy, every driver’s status, and every potential third-party defendant. In serious cases, this investigation is often the difference between a modest settlement and a fully compensated claim.

SB 371: Major Rideshare Insurance Changes Effective January 1, 2026

If you are a passenger in an Uber or Lyft, or you are hit by a rideshare driver, Senate Bill 371 introduces significant changes to UM/UIM coverage requirements for Transportation Network Companies (TNCs) in California.

Under the law, rideshare insurance operates in three phases:

  • Phase 1: App on, driver waiting for a ride request
  • Phase 2: Driver has accepted a ride and is on the way to pick up a passenger
  • Phase 3: Passenger is in the vehicle until drop-off

Historically, Phase 3 carried the highest insurance limits. Effective January 1, 2026, SB 371 reduces UM/UIM coverage requirements during Phase 3 for Uber and Lyft passengers injured by uninsured or underinsured drivers. The practical impact is that injured rideshare passengers may have less rideshare UM/UIM coverage available than they did before, which makes their personal UM/UIM policies even more important.

This change affects:

  • Passengers injured by uninsured drivers while in a rideshare vehicle
  • Catastrophic injury cases where prior Phase 3 limits would have provided significant additional recovery
  • Cases involving multi-vehicle collisions where coverage stacking matters

If you regularly use Uber or Lyft in Los Angeles, reviewing your personal UM/UIM limits with your own insurer is a worthwhile step.

Common Mistakes After an Uninsured Driver Accident

People hit by uninsured drivers often make decisions that hurt their claims:

  • Assuming there is no point in pursuing the case because the other driver “has nothing”
  • Filing a UM claim without understanding policy language and timelines
  • Giving a recorded statement to their own insurer without legal guidance
  • Accepting a quick UM settlement before treatment is complete
  • Missing the contractual deadlines built into UM/UIM policies

UM/UIM claims are contractual claims against your own insurer, which means your insurer may behave very differently than you would expect. They are not necessarily on your side, especially in serious injury cases.

What to Do After Being Hit by an Uninsured Driver

If you’ve been seriously hurt:

  • Get medical attention immediately, and follow all treatment recommendations
  • Report the incident to police and obtain a copy of the report
  • Document the scene with photos, videos, and witness contact information
  • Notify your own insurance company promptly, but limit detailed statements until you have legal guidance
  • Preserve all communications with insurers in writing
  • Speak with a personal injury attorney before signing anything or accepting any settlement offer

The earlier these steps are taken, the stronger the claim.

Frequently Asked Questions

What happens if an uninsured driver hits me in California?

You may still recover compensation through your own uninsured motorist (UM) coverage if you carry it. You may also have claims against vehicle owners, employers, or other responsible parties depending on the facts of the crash.

Is uninsured motorist coverage required in California?

No. California insurers must offer UM/UIM coverage, but drivers can reject it in writing. If you did not specifically reject it, you likely have it.

Can I sue an uninsured driver personally?

You can, but collecting on a judgment is often difficult or impossible if the driver has no assets. Most injured people focus on UM/UIM claims and any third-party policies that may apply.

How does SB 371 affect Uber and Lyft passengers?

Starting January 1, 2026, SB 371 reduces UM/UIM coverage requirements during Phase 3 (passenger in vehicle) for rideshare companies. Injured passengers should review their personal UM/UIM policies for added protection.

What if the uninsured driver fled the scene?

Hit-and-run accidents may still qualify for UM coverage if there is physical contact between vehicles. Filing a police report quickly is essential to preserve your right to a UM claim.

How long do I have to file a UM claim in California?

UM/UIM claims are governed by your policy contract, which often contains shorter deadlines than the general statute of limitations. Some policies require notice within days. Reviewing your policy promptly is critical.

Don’t Assume You Have No Options

The most damaging assumption injured people make after an uninsured driver accident is that nothing can be done. In many cases, that simply isn’t true. A careful policy review, a thorough investigation, and a strategic approach to UM/UIM coverage can produce meaningful recovery even when the at-fault driver carries nothing at all.

If you or someone you love has been seriously injured by an uninsured driver in Southern California, a free consultation with an experienced Los Angeles car accident lawyer can help you understand what coverage is available and what your next steps should be.
