Per occurrence limit is the single most misunderstood number on an auto insurance policy. It is the maximum your insurer will pay for all bodily injury claims arising from one accident, no matter how many people were hurt. On a standard split-limit policy written as 25/50/25, that $50,000 middle number is the per occurrence limit.
Most drivers assume each injured person gets a full payout. However, that is not how the math works. Once the per occurrence limit is exhausted, the insurer stops paying and you become personally responsible for the rest. With the average liability claim for bodily injury or property damage running $31,663 between 2017 and 2021, a multi-victim crash can blow past state minimums fast.
How a Per Occurrence Limit Actually Works on Your Policy
Auto liability coverage is usually written as three numbers separated by slashes. The Insurance Information Institute and IRMI both describe this structure as “split limits.” The first number is the per person limit. The second is the per occurrence limit for bodily injury. The third is property damage per accident.
Take a 100/300/100 policy. That means $100,000 per injured person, $300,000 per occurrence limit for the whole crash, and $100,000 for property damage. If you injure four people and each has $90,000 in medical bills, the total is $360,000. Your insurer pays $300,000. You owe the remaining $60,000 out of pocket.
Notice the interaction between the two numbers. No single person can collect more than $100,000, even though the per occurrence limit is $300,000. For example, if one passenger suffers a catastrophic injury with $400,000 in bills and is the only claimant, you still only get $100,000 of coverage. The per occurrence limit is a ceiling on the accident, not a pool any one claimant can drain. In most cases, that distinction only becomes obvious after a claim is filed.
Some policies use a combined single limit instead. A CSL of $500,000 gives you one bucket for bodily injury and property damage together. There is no separate per person cap. As a result, a CSL policy is more flexible in a severe single-victim crash, though it typically costs a bit more.
State Minimums and Why the Per Occurrence Limit Falls Short
Every state that requires liability insurance sets a mandatory floor. The most common minimum is 25/50/25. That is a $50,000 per occurrence limit for bodily injury. Louisiana requires just 15/30/25, and Iowa sits at 20/40/15. Alaska and Maine require 50/100, double what most states demand. New Jersey raised its floor to 35/70/25 effective January 1, 2026. California, North Carolina, Utah, and Virginia all increased their minimums during 2025.
Here is what different limit structures look like in practice.
| Split Limit | Per Person BI | Per Occurrence Limit (BI) | Property Damage |
|---|---|---|---|
| 15/30/25 | $15,000 | $30,000 | $25,000 |
| 25/50/25 | $25,000 | $50,000 | $25,000 |
| 50/100/50 | $50,000 | $100,000 | $50,000 |
| 100/300/100 | $100,000 | $300,000 | $100,000 |
| 250/500/250 | $250,000 | $500,000 | $250,000 |
Medical costs are the problem. A single hospital stay with surgery and rehabilitation can exceed $100,000. A serious highway crash can generate $700,000 in bodily injury claims against one at-fault driver. A $50,000 per occurrence limit disappears in hours. The cost of defending personal injury lawsuits rose roughly 7.1% per year from 2016 to 2022, which pushes settlement demands higher every year.
There is one piece of good news. Legal defense costs are typically paid outside the per occurrence limit. Your insurer hires and pays the defense lawyer without eating into your $300,000. However, once the insurer tenders the full per occurrence limit to claimants, its duty to defend usually ends.
Choosing the Right Per Occurrence Limit for Your Situation
The standard guidance is simple. Your per occurrence limit should roughly cover your net worth plus future earnings that a court could reach. Plaintiffs’ attorneys pursue assets when insurance runs out. Wages can be garnished. Homes can have liens attached.
Follow these steps to set your limits properly.
First, add up your assets. Include home equity, savings, retirement accounts not protected by state law, and vehicles. If that total is $250,000, a $50,000 per occurrence limit leaves you badly exposed. Second, price the upgrade. Moving from 25/50/25 to 100/300/100 typically costs $150 to $400 more per year. Jumping to 250/500/250 often adds only another $100 to $200 on top of that. Liability coverage is priced on a curve, so the higher tiers get cheaper per dollar of protection.

Third, consider an umbrella policy. A $1 million personal umbrella sits above your auto per occurrence limit and typically costs $150 to $300 per year according to III figures, though real-world quotes often land between $300 and $500. Most carriers require underlying auto limits of 250/500/100 before they will write one. Fourth, match your uninsured motorist limits to your liability limits. Roughly one in seven drivers is uninsured nationally, so your own UM per occurrence limit protects you when the other driver has nothing.
Finally, review your declarations page annually. Check the exact split-limit figures printed there. If you have had a raise, bought a home, or added a teen driver, your old per occurrence limit is probably outdated.
Frequently Asked Questions
What is the difference between per person and per occurrence limit?
The per person limit caps what any single injured claimant can collect. The per occurrence limit caps what your insurer pays for the entire accident combined. For example, on a 100/300 policy, no one person gets more than $100,000 and the crash total never exceeds $300,000.
Does the per occurrence limit reset for each accident?
Yes. Typically the limit applies fresh to every separate accident during the policy term. As a result, two crashes in one year each get their own full per occurrence limit. Personal auto policies generally do not carry an annual aggregate cap the way some commercial policies do.
What happens if damages exceed my per occurrence limit?
You are personally liable for the difference. The insurer pays up to the limit and then steps back. In most cases, claimants pursue a judgment against your assets and future wages, which is exactly why an umbrella policy is worth the modest annual premium.
