Your State Minimum Auto Limits Are a Joke. Here's What to Do About It.

I'll say the unpopular thing first: if you're carrying only your state's minimum auto liability limits, you are underinsured. Most drivers treat the state minimum as a target. It's not a target — it's a floor, and it's a dangerously low one.

Here's why that matters more than the endless arguments about which insurer has the friendliest app. Liability coverage pays for damage or injury you cause to others, while collision covers your own car in a crash and comprehensive handles non-collision damage like theft, fire, and hail (Investopedia). In a serious at-fault crash, the part that can wreck your finances is the liability side, because the other driver's injuries and property damage can easily exceed a minimum limit. And with roughly 13 percent of U.S. drivers uninsured, according to the Insurance Information Institute, the odds of you being on either side of an underinsured claim are higher than most people assume.

So let me walk through a concrete scenario. Imagine you are a 34-year-old driver in a mid-size metro area. You carry a typical $500 deductible, you've never had an at-fault accident, and you've been coasting on the state minimum liability limits because the premium was cheap. You're stopped at a red light. You glance at your phone, the light turns green, the car ahead hasn't moved yet, and you rear-end a late-model SUV at maybe 20 mph. No one is dramatically hurt, but the other driver goes to the ER with neck pain, misses a week of work, and their rear bumper, sensors, and liftgate need replacing.

Now run the numbers. The average auto liability claim for bodily injury was $24,211 in 2022, and the average property damage liability claim was $5,313 (III — Auto Insurance Facts & Statistics). Those are averages, not worst cases, and they're already comfortably above many state minimums. If your state minimum is, say, $25,000 per person for bodily injury and $25,000 for property damage, a single injury claim at the average plus the property damage claim can push you close to or past your limit. Anything above your limit comes out of your pocket — wages, savings, future earnings. The other driver's insurer doesn't care that you bought the cheapest legal policy.

Why the 'cheapest legal policy' instinct backfires

I understand the appeal. Premiums have been brutal. Motor vehicle insurance costs, as measured by the BLS Consumer Price Index, rose 17.4 percent in 2023 — far outpacing the 4.1 percent increase in overall consumer prices (III — Auto Insurance Facts & Statistics). When your renewal jumps, trimming coverage feels like the only lever you control. But trimming liability is the wrong lever. Liability limits are relatively cheap to raise compared to the cost of a single serious claim. The countrywide average auto insurance expenditure was $1,062 per vehicle in 2021, up 1.4 percent from $1,046 in 2020, according to NAIC data cited by the Insurance Information Institute. That's the average — meaning plenty of drivers pay less, and many pay more. If you're paying around average and your limits are minimal, you're getting a bad deal on the most important part of the policy.

The smarter move is to raise liability limits and, if you need to offset the premium, raise your deductible. Auto deductibles are typically $500 or $1,000, and the higher the deductible, the lower the premium (III — How Much Auto Coverage). A $1,000 deductible instead of $500 saves money every month and only costs you an extra $500 if you actually file a collision or comprehensive claim. That's a trade I'll make every time. The average collision claim was $5,992 and the average comprehensive claim was $2,738 in 2022. If you're already looking at a multi-thousand-dollar repair, the difference between a $500 and $1,000 deductible is a rounding error compared to the liability protection you bought with the savings.

The comparison that actually matters

Here's how the two strategies stack up for our hypothetical driver.

Notice the asymmetry. The downside of the higher deductible is capped at $500. The downside of low liability limits is uncapped. That's not a close call.

What I'd actually do, step by step

First, pull your declarations page and find your liability limits. If they're at or near your state's minimum, that's your signal. Second, price out a jump to the next tier or two of liability coverage. In most cases the increase is smaller than people fear, especially if you also move the deductible from $500 to $1,000. Third, keep comprehensive and collision if your car is worth enough to replace. About 80 percent of insured drivers buy comprehensive and 76 percent buy collision, based on a Triple-I analysis of 2021 NAIC data. If you're in the minority skipping them on a car you couldn't afford to replace out of pocket, reconsider.

If you truly cannot get coverage in the private market — say, after a DUI or a string of violations — know that every state and the District of Columbia runs an assigned risk plan, the shared or residual market, to guarantee availability (III — Auto Insurance Facts & Statistics). And if you're ever ordered to file an SR-22 after a DUI, driving uninsured, or an uninsured at-fault accident, understand it's not a policy at all. It's a form your insurer files with the state certifying you carry the required minimum liability coverage (GAINSCO — SR-22). It's proof, not protection.

• Check your declarations page today and write down your per-person and per-accident liability limits.
• Get quotes at the next two higher liability tiers before your next renewal.
• If the premium still stings, raise the deductible to $1,000 rather than cutting liability.
• Keep collision and comprehensive on any car you couldn't replace with cash.

One more thing worth knowing: if you have meaningful assets, a personal umbrella policy can add liability coverage above your auto and home limits, typically $1 million or more. Most insurers want about $250,000 of auto liability and $300,000 of homeowners liability before they'll sell you one (III — Umbrella Liability Policy). That's another reason to raise your auto limits now — it opens the door to cheap excess protection later.

The single most important thing to remember: your state's minimum liability limit is a legal floor, not a financial plan. Buy the highest liability limits you can reasonably afford, use your deductible as the pressure valve, and stop treating the cheapest legal policy as a win.
