What Is a Good Car Insurance Liability Coverage Amount

A good liability amount covers what you actually own, not just the minimum your state lets you buy.

What decides the right number for you

  • What you own Your assets are what a lawsuit could go after if you cause a serious crash. Add up savings, a home's equity and anything else with value before picking a limit.
  • Minimum limits are too thin State minimums were set to meet a legal requirement, not to cover a real accident. One hospital visit after a crash can cost more than the minimum pays out.
  • Split limits versus combined Some policies split coverage between per-person and per-accident injury limits plus property damage. Check which structure your insurer uses before comparing numbers across quotes.
  • Married households and assets If you're combining policies, your combined assets matter together, not separately. Decide your limit based on what you'd both stand to lose, not just one driver's history.
  • Umbrella coverage helps too If your assets are substantial, a personal umbrella policy can extend liability beyond your auto limits. Ask your insurer what underlying limit it requires before you qualify.

The short version

A good liability amount is one that covers what you own, not just your state's minimum. Minimums were built to satisfy a legal requirement, not a real accident. Add up your assets, pick a limit that protects them, and get quotes at that level.

Should both spouses carry the same liability limit?

Yes, in almost every case. Liability coverage protects your household's shared assets, so a mismatch between two policies doesn't actually protect you the way it seems to.

If one spouse carries a low limit and causes an accident, the damage can still reach joint savings, a shared home or future wages, even if the other spouse's policy was stronger. Insurers price each driver separately based on their own record, but the protection you're buying is meant to cover the household, not just one name on a title. When you combine policies or add a spouse, ask your insurer to set both drivers at the same liability limit, matched to what you own together rather than what either of you owned alone before marriage.

Now that you know what limit fits your situation, compare quotes at that level and see what combining would cost.

A couple combining policies after the wedding

A couple in their early thirties got married and started looking at combining their car insurance. One had a clean record and minimum liability limits from years of driving an older car. The other had a newer car, a ticket from a few years back and higher limits already in place because a parent had insisted on it when they first got licensed.

Instead of keeping the mismatch, they added up what they now owned together, including savings and the equity in a condo they'd just bought. They raised both policies to the same higher liability limit before combining them under one insurer. The ticket on one record pushed the combined price up some, but matching both limits meant neither of them was personally exposed if the other caused a serious accident. They treated the higher limit as the cost of protecting what they'd just built together, not as a penalty for one person's history.

The number that matters is what you'd lose in a bad accident, not the smallest number your state allows.

Does raising liability limits increase my premium a lot?

It raises your premium some, but usually less than people expect compared to the protection it adds. The jump from a state minimum to a solidly higher limit is often a modest increase, because insurers price the first layer of coverage higher than the layers above it. Get quotes at a few different limits side by side before deciding, since the difference in cost is usually smaller than the difference in protection.

Will my spouse's driving record raise my liability rate too?

It can, once you're on the same policy, because insurers price the household based on all listed drivers. A record with tickets or accidents affects the shared premium, not just that person's share of it. Some insurers let you keep separate policies if the gap in records is large enough that combining costs more than staying separate, so it's worth checking both ways before you commit.

Do I need to change my liability limit after a name change?

No, a name change itself doesn't require a different liability limit. But a name change often happens alongside combining households, moving, or retitling a car, and any of those is a good moment to recheck your limit against what you now own. Update the name on the policy and title separately from deciding on coverage amounts, since they're two different conversations with your insurer.
