The Complete California Auto Insurance Coverage Guide (2026 Edition)
California’s auto insurance laws changed significantly in 2026. If you’re still driving with pre-SB 1107 minimums — or if you’ve never fully understood what your policy actually covers — you may be taking on serious financial risk without knowing it.
This guide covers every major coverage type, what it pays for, and where the gaps are. For a deeper foundation, start with our overview of automobile insurance types of coverage and their purpose.
California’s 2026 Mandatory Liability Minimums (SB 1107)
Liability insurance is mandatory for every California driver. It covers injuries and property damage you cause to others — not your own vehicle or medical bills.
SB 1107 raised the state minimums that had been in place since 1967. Driving with the old 15/30/5 limits is no longer legal as of 2025.
The 2026 minimums:
- $30,000 per person for bodily injury
- $60,000 per accident for bodily injury
- $15,000 per accident for property damage
Bodily Injury Liability
Bodily injury liability coverage pays the medical expenses, lost wages, and pain and suffering of anyone you injure in an at-fault accident — and covers your legal defense costs if you’re sued.
The new minimums are higher than before, but $30,000 per person is still quickly exhausted in serious accidents. When damages exceed your policy limits, your personal assets — savings, home equity, future wages — can be targeted in a lawsuit. Understanding how liability coverage works before a collision is the difference between being protected and being financially exposed.
Property Damage Liability
Property damage liability covers the repair or replacement of the other driver’s vehicle or any other property you damage. At $15,000 minimum, this limit is still low relative to the cost of most newer vehicles. Consider carrying $50,000–$100,000 if you want real protection.
Covering Your Own Vehicle: Collision vs. Comprehensive
Liability pays for the other driver’s losses. To protect your own car, you need separate coverage.
Collision Coverage
Collision coverage pays to repair or replace your vehicle after an accident — regardless of fault. Whether you were rear-ended on the freeway or hit a median barrier, collision pays after your deductible.
If your car is financed or leased, your lender almost certainly requires it. For older vehicles worth less than $4,000–$5,000, weigh the annual premium against the car’s actual cash value before renewing.
Comprehensive Coverage
Comprehensive coverage protects against non-collision losses: theft, fire, flooding, vandalism, falling objects, and animal strikes. See how comprehensive coverage works in practice — including what it excludes.
California drivers in wildfire zones or high-theft urban areas have particular reason to carry it. Like collision, it comes with a deductible, and it’s typically required under a car loan or lease.
Gap Insurance
If you financed your vehicle recently, standard collision and comprehensive payouts are based on market value — which may be less than what you still owe on your loan. Gap insurance covers that difference so you’re not paying off a totaled car.
Medical Payments Coverage (MedPay): Immediate, No-Fault Benefits
After an accident, medical treatment can’t always wait for an insurance investigation to resolve. Medical payments coverage (MedPay) fills that gap.
MedPay is no-fault — it pays regardless of who caused the crash, covering you, your passengers, and household family members for:
- Emergency room and hospital bills
- Ambulance costs
- Surgery and follow-up care
- Chiropractic, acupuncture, and specialist visits not covered by health insurance
- Funeral expenses
MedPay limits typically range from $1,000 to $25,000. It’s inexpensive to add and can prevent medical debt from accumulating while a liability dispute is still open. There’s also a MedPay reimbursement consideration to understand: if you settle a claim, your insurer may seek reimbursement for MedPay payments — your attorney can often negotiate this down. Learn more about how medical payments coverage works.
Uninsured & Underinsured Motorist Coverage: The Coverage Most People Underestimate
California has one of the highest rates of uninsured drivers in the country — estimates consistently put it above 16%. Even insured drivers often carry the bare minimums, which fall far short in serious accidents.
Uninsured Motorist (UM) Coverage
Uninsured motorist coverage protects you when the at-fault driver has no insurance at all — including hit-and-run accidents where the driver flees. UM is optional in California but automatically offered with every liability policy; you must explicitly waive it in writing to remove it.
The firm recommends carrying at least $100,000 per person / $300,000 per accident in UM coverage. Here’s why UM coverage is worth buying even when it’s optional. There’s also a separate UM property damage coverage that covers your vehicle when an uninsured driver hits it.
Underinsured Motorist (UIM) Coverage
Underinsured motorist coverage kicks in when the at-fault driver has insurance, but not enough. If someone with a $30,000 policy causes an injury worth $150,000, your UIM coverage bridges the gap — up to your own policy limits.
One critical rule: your UM/UIM limits cannot exceed your liability limits. If you carry $30,000 in liability, you cannot get more than $30,000 in UM/UIM. Raising both together is often the smarter move.

First-Party vs. Third-Party Claims: Who Do You Deal With?
One of the most confusing aspects of an accident is knowing whose insurer to call. Understanding the difference between first-party and third-party claims before you need it matters. See also our detailed breakdown at auto coverage and first-party vs. third-party claims.
| Claim Type | Filed Against | Example |
|---|---|---|
| First-party | Your own insurer | Collision, MedPay, UM/UIM |
| Third-party | At-fault driver’s insurer | Bodily injury, property damage |
First-party claims are governed by your policy contract. Your insurer owes you a duty of good faith under California law, and unreasonable delays or denials can be challenged.
Third-party claims are filed against the at-fault driver’s insurer. That company’s obligation runs to their policyholder — not you. They may dispute liability, delay, or lowball. This is where experienced legal representation materially changes outcomes.
Additional Coverage Worth Knowing
Umbrella Insurance
A personal umbrella policy provides excess liability coverage above your auto policy limits — typically starting at $1 million — for roughly $150–$300 per year. If you have significant assets, it’s one of the cheapest risk-reduction tools available. Should you buy a personal umbrella policy? — that page walks through the calculation.
Rideshare Coverage
If you drive for Uber or Lyft, your personal auto policy almost certainly doesn’t cover you while the app is active. California requires a rideshare endorsement or commercial policy. Our California rideshare insurance guide covers the coverage periods, gaps, and what to do if you’re in an accident while driving for a TNC.
