What Is a Good Amount of Liability Coverage
A good amount of liability coverage is enough to cover everything you own, not just the state minimum.
Why the state minimum stops protecting you the day your teen drives
Liability coverage pays for the other person's damage when your driver is at fault, and it pays up to your limit and no further. State minimums were set to get cars on the road legally, not to match what a serious crash actually costs. A new driver changes the math because teens have more at-fault accidents per mile than any other age group, so the odds of hitting your limit go up the moment they're on your policy.
When a claim goes past your limit, the gap doesn't disappear. The person you hit can sue your family directly for the rest, and that claim can reach savings, home equity, and future wages, not just the car. This is why the right number isn't about what the car costs or what you can afford monthly. It's about what you'd lose if your teen caused real harm.
A reasonable target is coverage that roughly matches or exceeds your household's net worth, including home equity and savings, because that's what a lawsuit would actually be reaching for. Some households get there through higher limits on the auto policy alone. Others add a separate umbrella policy, which sits on top of your auto liability and often costs less than you'd expect for a large amount of extra protection, though it usually requires your underlying auto limits to already be at a certain level.
What counts as enough varies by state, since rules on lawsuits, wage garnishment, and home equity protection differ. Check your state's rules on underinsured motorist coverage too, since that protects your own family if someone else's low limit hits you.
What to check before you pick a number
- Your net worth, roughly Add up savings, home equity, and anything else a lawsuit could reach. That rough number is your floor, not your ceiling.
- Split limits vs combined Policies list per-person and per-accident amounts, or one combined number. Ask your insurer to show both so you know what a multi-injury crash would actually pay.
- Umbrella eligibility Ask what underlying auto limit is required to qualify for an umbrella policy. If you're below it, raising auto liability first may be the cheaper path.
- Underinsured motorist limits This protects your own teen if someone else's coverage falls short. Match it to your liability limit so one weak link doesn't undo the rest.
- State lawsuit rules Some states limit wage garnishment or protect home equity differently. Ask an agent what's actually exposed where you live before settling on a number.
The real question isn't what you can afford monthly, it's what you can afford to lose.
Once you know the limit that covers what you have to lose, compare quotes set at that limit, not the state minimum.
A family raises their limits before their son starts driving
A couple had carried their state's minimum liability for over a decade without a second thought, since they'd never filed a claim. When their son got his license, they ran their numbers. Between home equity and retirement savings, they had far more to lose than their old limit would cover. They asked their agent to quote a much higher liability limit and also priced out an umbrella policy.
The umbrella required raising their auto liability to a specific underlying level first, which cost more monthly than they expected. But comparing that cost against the size of the gap it closed made the decision easy. They raised the auto limit, added the umbrella, and also bumped their underinsured motorist coverage to match, since their agent pointed out that otherwise a crash caused by someone else with low coverage would leave their own son undercovered. The new setup cost more than their old policy, but it closed the gap between what they had and what they stood to lose.
Does raising liability limits cost a lot more per month?
Usually less than people expect, because liability coverage is priced in tiers and higher tiers add less per step than the first dollar of coverage does. The jump from your current limit to a much higher one is often smaller than the jump from no coverage to minimum coverage was. Get an actual quote at the higher limit before assuming it's out of reach, since assumptions here are usually wrong in the expensive direction.
Should I put the car in my teen's name instead?
No, not for insurance purposes, and doing so can actually remove protections. Keeping the teen as a listed driver on your policy keeps your household liability limits in place for them. Titling a car separately doesn't lower your risk since you can still be sued as the parent in most situations, and it may complicate claims instead of simplifying them. Check with an agent before restructuring ownership for this reason alone.
Will a single at-fault accident wipe out my high limits?
A single accident can use up a limit if damages are severe enough, especially with injuries, but higher limits exist specifically to absorb that. The point of raising limits isn't to make claims impossible, it's to make a single bad accident survivable without reaching your savings or home. If you're worried about a limit being used up entirely, that's the strongest sign you need an umbrella policy layered on top.
