What Do the Three Numbers Mean on an Auto Insurance Policy
Those three numbers set your per-person injury limit, your per-accident injury limit, and your property damage limit, in that order.
Each number controls a different kind of payout
- First number This is the most your policy pays for injuries to one person in an accident you cause. If a single injury claim costs more than this, you're personally on the hook for the rest.
- Second number This is the total cap for all injuries in one accident, no matter how many people are hurt. If several people are injured, this number limits what the policy pays in total, not per person.
- Third number This is the most your policy pays for damage to someone else's car or property in one accident. Compare it to what cars actually cost to replace in your area, since repair and replacement costs vary.
- How they combine The first two numbers work together for injuries, and the third stands alone for property. Check your declarations page to see which three numbers apply to your policy.
Should I raise these numbers now that I'm reviewing the policy alone?
Possibly, and it's worth deciding deliberately rather than leaving it as your spouse set it years ago. Higher limits cost more, but they also protect more of what you own if you cause a serious accident. If your spouse chose these numbers long ago, your situation now, including what you own and what you'd lose in a lawsuit, may call for different limits.
There's no universal right number, since it depends on your assets and your state's rules. Some states set minimums far below what most people actually need to protect their savings or their home. Ask your insurer what it would cost to raise each number, and ask what your state requires versus what it allows. This is also a reasonable moment to ask someone you trust, like a financial advisor or an agent, whether your current limits match your situation today.
Deciding whether to review these numbers now
If you do
You'll know exactly what you're covered for and can adjust limits to fit your life now, not your spouse's old assumptions. If the policy is underinsured for your assets, you'll catch it before an accident forces the issue. It takes one phone call or a few minutes online.
If you don't
The policy keeps running on whatever limits were set before, which may or may not still fit your situation. If those numbers are too low and you're in a serious accident, you could be personally responsible for costs beyond what the policy pays. Nothing changes until you check.
Now that you know what each number covers, compare quotes to see what adjusting them would cost.
Why insurance is split into three separate numbers
Insurers separate injury coverage from property coverage because the two risks behave differently. A single injury can cost far more than a car is worth, so insurers cap injury payouts per person and then again per accident, which is why there are two numbers for injuries alone. Property damage gets its own single number because it's a more predictable, usually smaller cost.
The per-person limit exists because serious injuries, especially ones involving long-term care, can rack up costs that dwarf typical claims. Without a per-person cap, a single severe injury could use up funds that should also cover other people hurt in the same accident. The per-accident limit then protects against the case where multiple people are injured at once, spreading the total coverage across everyone involved rather than letting one large claim exhaust it.
Property damage is simpler because cars and property have more predictable values. One number covers the total cost of whatever you damage, whether it's one vehicle or several, a fence, or a storefront. This number matters more than people expect, because newer vehicles and specialty cars can cost more to repair than older assumptions about typical car values suggest.
Where this gets less uniform is in what your state requires versus what your insurer offers. Some states mandate low minimums that leave most drivers underinsured relative to their actual assets. Others set higher baselines. Your insurer can also offer higher limits than your state requires, and many people carry more than the minimum specifically because the minimum doesn't match modern medical or repair costs. Check your state's requirements separately from your policy's actual limits, since they're often not the same number.
What happens if a claim costs more than my limits?
You become personally responsible for the difference, and the other party can pursue your savings, wages, or other assets to cover it. This is the core risk of carrying low limits. Check whether your assets, including savings, home equity, or future wages, exceed your current limits, since that gap is what you'd be exposed for. If the gap is large, raising your limits is usually worth the added cost.
Does the property damage number cover my own car too?
No, that number only covers damage you cause to someone else's property. Your own vehicle is covered separately, through collision or comprehensive coverage if you carry it. Check your declarations page for those coverages listed separately from the three liability numbers. If you're unsure whether you have them, that's worth confirming now, especially if you're deciding whether to keep coverage on a car nobody drives.
Can I change these numbers without affecting other parts of the policy?
Yes, these liability numbers can usually be adjusted independently of other coverages like comprehensive or collision. Ask your insurer to walk through each coverage separately so you understand what's tied together and what isn't. Some discounts or bundled coverages may shift slightly with changes, so it's worth asking directly rather than assuming nothing else is affected.
