Car insurance coverage limits, explained
What those three numbers mean, what each one caps, and how to pick limits that actually protect you.
What a coverage limit is
A limit is a ceiling. It is the maximum your insurer will pay on a covered claim, and once it is reached the insurer stops - the rest is yours to pay out of pocket. That is different from a deductible, which is the amount you pay first before the insurer pays anything. A policy has both: the deductible is the floor you cover, the limit is the ceiling the insurer covers.
How to read the three numbers
Liability limits are almost always written as three numbers separated by slashes, in thousands of dollars. Using California's 30/60/15 minimum:
| Position | Coverage | What it caps |
|---|---|---|
| First (30) | Bodily injury, per person | The most paid for any single injured person |
| Second (60) | Bodily injury, per accident | The most paid for everyone injured, combined, in one accident |
| Third (15) | Property damage, per accident | The most paid for the other party's vehicle and property |
You will sometimes see a limit written as a single number, such as 100,000 dollars combined single limit (CSL). That is one pot covering both injury and property damage with no separate per-person cap - more flexible, and common on commercial policies.
Per person vs per accident
These two caps work together, and both apply. If you carry 30/60 and injure three people at 25,000 dollars each, no one person exceeds the 30,000 dollar per-person cap - but the total of 75,000 dollars exceeds the 60,000 dollar per-accident cap, so the policy pays 60,000 dollars and you owe the remaining 15,000 dollars. The per-accident number is not a bonus; it is a second ceiling that can bind before the first one does.
Limits on the coverages that protect you
Liability limits protect other people. The coverages that protect you have their own limits and their own logic.
- Uninsured/underinsured motorist (UM/UIM) - pays your injuries when the at-fault driver has no coverage or not enough. Usually offered to match your liability limits, and worth taking at that level. California insurers must offer it, and you have to decline it in writing.
- Collision - limited by your vehicle's actual cash value, not a number you pick. You choose the deductible, not the ceiling.
- Comprehensive - same structure as collision: capped at the vehicle's value, and you choose the deductible.
- Medical payments (MedPay) - a small flat limit, commonly a few thousand dollars, that pays your medical bills regardless of fault.
- Rental reimbursement - typically a per-day amount with a maximum number of days.
Note the pattern: liability and UM/UIM limits are choices you make. Collision and comprehensive ceilings are set by what your car is worth - so on those, the deductible is your real lever.
How to choose your limits
The purpose of liability coverage is to protect what you have and what you earn. A useful starting frame: your liability limit should be at least as large as your net worth plus a realistic estimate of future wages a court could reach. For most people that puts the state minimum far too low.
| Limit | How it is usually described | Who it tends to fit |
|---|---|---|
| 30/60/15 | California's legal minimum | Drivers with few assets who need to be legal at the lowest cost - and who accept real personal exposure |
| 50/100/50 | A modest step up | A meaningful improvement for a small premium difference |
| 100/300/100 | The common recommendation | Most drivers with a job, savings, or a home to protect |
| 250/500/100 | High limits | Higher earners and drivers with significant assets |
| Umbrella policy on top | 1 million dollars or more | Anyone who wants coverage past what an auto policy will write |
An umbrella sits above your auto and home liability and picks up where they stop. Carriers generally require you to carry specific underlying limits before they will sell you one, which is another reason the bare minimum can close doors later.
What happens when you exceed your limit
Your insurer pays up to the limit, and then its obligation to pay ends. The injured party can pursue you personally for the difference - through a judgment, wage garnishment, or a lien against property. Your insurer's duty to defend you generally continues while the claim is being handled, but the money stops at the limit.
This is the whole argument for higher limits: the gap between 30/60/15 and 100/300/100 is usually a small premium difference, and it is the difference between an insurer writing the check and a plaintiff coming after your paycheck. See California minimum car insurance requirements for a worked example of how fast the minimum runs out.
Limits and California's minimum
California raised its minimum liability limits to 30/60/15 on January 1, 2025 under Senate Bill 1107, up from 15/30/5, and the same law schedules another increase to 50/100/25 effective January 1, 2035. If you have carried the same policy for years, it is worth confirming your limits actually meet the current requirement.
Higher minimums are a floor, not a recommendation. The state is setting the least you may legally carry, not the amount that protects you.
Checking your own limits
Your limits are on your declarations page, the summary at the front of your policy, usually listed per coverage. If you are not sure what you have, send us the declarations page and we will read it back to you in plain English and tell you what raising each limit would actually cost. There is no charge for that.
Frequently asked questions
What does 30/60/15 mean on car insurance?
It is shorthand for three separate liability caps: 30,000 dollars for bodily injury to any one person, 60,000 dollars for all bodily injury in a single accident combined, and 15,000 dollars for property damage in a single accident. It is California's legal minimum, and anything above those caps is your personal responsibility.
What are car insurance coverage limits?
A coverage limit is the maximum your insurer will pay on a covered claim. Liability limits are chosen by you and written as three numbers; collision and comprehensive are capped at your vehicle's actual cash value instead. Once a limit is reached, the insurer stops paying and the rest falls to you.
What is the difference between a limit and a deductible?
A deductible is what you pay before your insurer pays anything; a limit is the most your insurer will pay after that. A policy has both - the deductible is your floor, the limit is the insurer's ceiling.
What coverage limits should I have?
A common guideline is to carry liability at least equal to your net worth plus realistic future wages, since those are what a judgment can reach. For most drivers with a job or savings that means something like 100/300/100 rather than the state minimum, and an umbrella policy above it if you have significant assets.
What is the difference between per-person and per-accident limits?
The per-person limit caps what is paid for any single injured individual; the per-accident limit caps the total paid for everyone injured in that accident. Both apply, and the per-accident cap can bind even when no individual claim exceeds the per-person cap.
What happens if a claim is more than my coverage limit?
Your insurer pays up to the limit and stops. The injured party can pursue you personally for the rest, including through a judgment, wage garnishment, or a lien on your property. Higher limits usually cost far less than most drivers expect.
Should I match my uninsured motorist limits to my liability limits?
Usually yes. Uninsured and underinsured motorist coverage pays your injuries when the at-fault driver has nothing, and it is typically inexpensive to carry at the same level as your liability. California insurers must offer it, and declining it requires a written waiver.
