What Happens When an Uninsured Driver Hits You in California?
California requires all drivers to carry minimum liability insurance ($15,000/$30,000/$5,000). But roughly 17% of California drivers — approximately 4.5 million people — have no insurance at all. Another significant percentage carry only the minimum, which is wholly inadequate for serious injury claims.
When you're hit by an uninsured driver, you cannot collect from a policy that doesn't exist. Without Uninsured Motorist coverage on your own policy, your only recourse is a direct lawsuit against a driver who, by definition, couldn't afford insurance and almost certainly cannot pay a judgment.
How Uninsured Motorist (UM) Coverage Works
UM/UIM coverage is an endorsement on your own auto insurance policy. When an uninsured driver causes your injuries, your own insurer steps into the at-fault driver's shoes and pays your damages — up to your UM limit — as if they were the at-fault driver's insurer.
UM vs. UIM — What's the Difference?
- Uninsured Motorist (UM): Applies when the at-fault driver has zero coverage or flees the scene (hit-and-run with physical contact)
- Underinsured Motorist (UIM): Applies when the at-fault driver has some coverage, but not enough to cover your damages. Your UIM limit minus their liability limit = your available UIM
- Example: At-fault driver has $15K coverage. Your damages are $120K. Your $100K UIM coverage pays $85K (100K - 15K already paid by their insurer)
UM/UIM Coverage Stacking in California
If you own multiple vehicles — or multiple household members have separate policies — California law may allow you to "stack" coverage across multiple policies, multiplying the available limits. This is a critical strategy in cases with catastrophic injuries where single-policy limits are insufficient. We analyze every applicable policy in every case.
What UM/UIM Covers
- All medical expenses — ER, surgery, hospitalization, physical therapy, future care
- Lost wages and future loss of earning capacity
- Pain and suffering — physical and emotional
- Property damage (UMPD) — some policies include this separately
- Death benefits if a family member was killed by an uninsured driver
Your Own Insurer Will Fight You
This is the uncomfortable reality of UM/UIM claims: your own insurance company is now the adverse party. The adjuster handling your claim answers to the same company that collected your premiums — and that company's financial interest is to minimize your payout.
Common insurer tactics in UM/UIM cases:
- Disputing the severity of your injuries ("the impact wasn't severe enough")
- Claiming your injuries are pre-existing
- Offering a quick, inadequate settlement before you're at Maximum Medical Improvement
- Demanding an Examination Under Oath (EUO) and using your answers against you
- Requesting an Independent Medical Examination (IME) — using a doctor who routinely minimizes injuries
- Invoking binding arbitration clauses to avoid jury trials
UM Arbitration — Know Your Rights
Most California auto policies include an arbitration clause for UM/UIM disputes. This means if negotiations fail, your case goes to a private arbitrator — not a jury. Arbitration outcomes are typically lower than jury verdicts. An attorney who understands UM arbitration strategy is essential to maximizing your recovery.
