Automotive liability insurance pays for damage or injuries you cause to someone else in a car accident

Automotive liability insurance is the part of your car insurance that covers medical bills, lost wages, and property damage when you're found responsible for an accident. If you hit another car, injure a pedestrian, or damage someone's fence, your liability coverage pays their costs — up to the limits you chose when you bought the policy. This is different from collision or comprehensive coverage, which pay for damage to your own vehicle.

Every state except New Hampshire requires you to carry some amount of liability insurance before you can legally drive. The state sets a minimum, but that minimum is often too low to protect your personal assets if a serious accident happens. Understanding what your policy covers and what it doesn't is the first step toward knowing whether you're adequately protected.

Key Takeaways

  • Liability insurance covers medical expenses, lost income, and property damage you cause to others, but not damage to your own car.
  • Every state sets a minimum liability limit you must carry, but minimums are typically far lower than the actual cost of a serious accident.
  • Your policy has two separate limits: bodily injury per person and per accident, plus a property damage limit, and you pay only up to those amounts.
  • If an accident exceeds your liability limits, you can be sued personally for the difference, which is why many people carry umbrella insurance on top of their auto policy.

How liability limits work and what the numbers mean

When you buy liability insurance, you choose coverage limits written as three numbers, like 25/50/25. The first number is the maximum paid for bodily injury to one person, the second is the maximum paid for bodily injury across all people in one accident, and the third is the maximum paid for property damage in one accident. All amounts are in thousands of dollars, so 25/50/25 means $25,000 per person, $50,000 per accident for injuries, and $25,000 for property damage.

State minimums vary widely. Some states require as little as 15/30/5 (meaning $15,000 per person, $30,000 total per accident for injuries, and $5,000 for property damage). Others require 25/50/25 or higher. You can find your state's minimum by contacting your insurance company or checking your state's insurance commissioner's website.

The catch is that state minimums rarely match the real cost of a serious accident. A single hospitalization can easily exceed $100,000. If you cause an accident that injures multiple people or damages an expensive vehicle, your liability limit can be exhausted quickly. Once your policy limit is reached, you are personally responsible for any remaining costs.

What liability insurance does and does not cover

Liability insurance covers medical treatment, rehabilitation, lost wages, and pain and suffering for people you injure. It also covers property damage — another person's car, a building, a fence, or any other property you damage. The insurance company will pay the injured party's medical bills directly and negotiate settlements with their lawyers if they sue.

Liability insurance does not cover damage to your own vehicle, injuries to you or your passengers, or medical payments you choose to make out of pocket. It also does not cover intentional damage, criminal acts, or accidents that happen while you're using your car for commercial purposes (like rideshare or delivery) unless you have a commercial auto policy. If you cause an accident while driving under the influence, your insurer may refuse to pay and may cancel your policy.

One common misunderstanding: liability insurance does not cover the other driver's rental car or loss of use while their car is being repaired. Some policies include this as an add-on called "loss of use" coverage, but it is not automatic.

Why state minimums are usually not enough

A serious accident involving multiple injuries or an expensive vehicle can generate costs far beyond what state minimums cover. A person hospitalized for a week with surgery and ongoing physical therapy might have medical bills of $150,000 or more. If that person is a high-income earner, they can also sue for lost wages and future earning capacity. Damage to a luxury vehicle can easily reach $50,000 to $100,000.

If your liability limits are exhausted, the injured party can sue you personally for the remaining amount. This means your wages can be garnished, your bank accounts frozen, or your home placed at risk — depending on your state's laws. Many people carry liability limits of at least 100/300/100 ($100,000 per person, $300,000 per accident, $100,000 property damage) or higher for this reason.

The cost difference between state minimum coverage and higher limits is usually modest — often $10 to $30 per month for a significant increase. Insurance companies price higher limits as a small add-on because the risk of paying out a very large claim is still relatively low.

Umbrella insurance as a second layer of protection

Umbrella insurance is a separate policy that covers costs above your auto liability limits. If you have a 100/300/100 auto policy and cause an accident that results in $400,000 in damages, your auto policy pays $300,000 (the per-accident limit) and your umbrella policy pays the remaining $100,000, up to its own limit.

Umbrella policies typically start at $1 million in coverage and cost $150 to $300 per year. They require you to carry minimum underlying liability limits on your auto policy — usually 100/300/100 or higher — before you can buy them. Umbrella insurance also covers liability claims that arise outside of driving, such as someone injured on your property or a dog bite, which is another reason many homeowners carry it.

Whether you need umbrella insurance depends on your assets and risk tolerance. If you own a home, have significant savings, or earn a high income, umbrella insurance protects those assets from a lawsuit following a serious accident. If you have few assets, the additional protection may not be worth the cost.

How liability claims are handled after an accident

After an accident, you report it to your insurance company, usually within a few days. You provide a description of what happened, the other driver's information, and any police report number. Your insurer then assigns a claims adjuster who contacts the other driver, reviews police reports, and gathers evidence about who was at fault.

If you are found at fault, your insurer will typically offer to settle with the other driver or their lawyer. Settlement negotiations can take weeks or months, especially if injuries are serious or liability is disputed. Once a settlement is reached, your insurer pays it from your liability coverage, up to your policy limits. If the other driver refuses to settle and sues you, your insurer provides a lawyer to defend you.

Throughout this process, you are protected by your policy limits. The insurance company handles communication with the other party and their lawyers. You do not pay anything out of pocket unless the claim exceeds your liability limits, in which case you become personally liable for the excess.

Choosing the right liability limits for your situation

Start by checking your state's minimum requirement, then consider whether that minimum is enough for your circumstances. If you own a home, have savings, or earn a steady income, carrying limits higher than the minimum protects those assets. A common recommendation is to carry limits equal to your net worth, or at least 100/300/100 if your net worth is higher than that.

Consider also the types of vehicles you drive and the areas where you drive most. If you frequently drive in urban areas with heavy traffic, your accident risk is higher. If you drive an older, less expensive car, you may cause less property damage in an accident, but you could still cause serious injuries.

Review your policy limits every few years, especially if your financial situation changes. As your assets grow, your liability exposure grows too. Conversely, if you pay off your home or reduce your savings, you may be comfortable with lower limits. Your insurance agent can help you understand what limits make sense for your situation.

Frequently Asked Questions

Does my liability insurance cover damage to my own car?

No. Liability insurance covers damage you cause to other people and their property. Damage to your own vehicle is covered by collision insurance (if you hit another car or object) or comprehensive insurance (if your car is stolen, vandalized, or damaged by weather). These are separate coverages you purchase in addition to liability.

What happens if I cause an accident and don't have insurance?

Driving without insurance is illegal in every state except New Hampshire. If you cause an accident without insurance, you are personally responsible for all damages, and the injured party can sue you. You may also face fines, license suspension, and criminal charges depending on your state. Some states require you to post a bond or carry an SR-22 form for several years after an uninsured accident.

Can my insurance company refuse to pay a liability claim?

Yes, in certain situations. If you were driving under the influence, using your car for commercial purposes without a commercial policy, or intentionally caused the accident, your insurer may deny the claim. If you misrepresented information on your policy process, the insurer may also refuse to pay. This is why it's important to be honest and accurate when you purchase your policy.

If I'm found partially at fault for an accident, does my liability insurance still pay?

This depends on your state's fault rules. In "at-fault" states, your liability insurance pays only if you are found fully or primarily at fault. In "comparative fault" states, your insurance pays a percentage of damages based on your percentage of fault. In "no-fault" states, each driver's own insurance pays their own damages regardless of who caused the accident, though you can still sue for serious injuries.

How long does a liability claim take to settle?

straightforward claims with clear liability and minor injuries often settle within a few weeks. Claims involving serious injuries, multiple parties, or disputed fault can take several months or longer. Your insurance company will keep you informed of progress, but you have little control over the timeline once the claim is filed.
