What liability-only insurance covers and costs

Liability-only insurance pays for damage or injury you cause to someone else — their car, their medical bills, their property. It does not pay for damage to your own vehicle, no matter who caused the accident. This is the minimum coverage required by law in every state, though the dollar amounts vary.

Liability-only is the cheapest form of car insurance because the insurer's risk is limited. They are not paying to fix your car, which is often the largest expense in a claim. A driver with an older paid-off vehicle, a safe driving record, and the ability to cover their own repairs out of pocket can cut their premium significantly by dropping collision and comprehensive coverage and keeping only liability.

The actual cost depends on your state's minimum requirements, your age, driving history, the car you drive, how much you drive, and which company you choose. A 40-year-old with no accidents in a state with lower minimums might pay $40 to $80 per month. A 25-year-old with a ticket or a young driver in a high-cost state could pay $150 to $300 per month for the same coverage type.

Key Takeaways

  • Liability-only insurance is the legal minimum in all 50 states but the required dollar amounts differ — your state's Department of Insurance website lists your state's minimums.
  • You pay nothing toward repairs to your own car under liability-only coverage, whether the accident was your fault or not.
  • Liability-only makes sense for older vehicles you own outright and can afford to replace or repair yourself, not for financed or leased cars.
  • Your actual monthly cost depends on your age, driving record, location, and the insurer — comparing quotes from at least three companies is the only way to find the lowest price.

State minimum liability limits and what they mean

Every state sets a minimum amount of liability coverage you must carry. These minimums are written as three numbers — for example, 25/50/25 — which represent bodily injury per person, bodily injury per accident, and property damage per accident, in thousands of dollars.

A 25/50/25 minimum means the insurer will pay up to $25,000 toward one person's injuries, up to $50,000 total for all injuries in one accident, and up to $25,000 for property damage. If you cause an accident that injures three people and damages two cars, and your total liability exceeds these limits, you are personally responsible for the rest.

Some states have lower minimums (15/30/5 in states like Kentucky or South Carolina) and some have higher ones (50/100/50 in states like Maine). A few states allow drivers to post a bond or prove financial responsibility instead of buying insurance, but this is rare and usually more expensive. Check your state's Department of Insurance or Secretary of State website to find your state's exact minimums — this is the coverage floor you cannot go below legally.

When liability-only makes financial sense

Liability-only works best when your car is worth less than the cost of adding collision and comprehensive coverage for several years. If your car is worth $3,000 and collision coverage costs $50 per month, you would pay $600 per year for coverage that might never pay out. If you can absorb a $3,000 loss, liability-only is the rational choice.

This calculation changes if you owe money on the car. If you have a loan or lease, your lender or leasing company requires you to carry collision and comprehensive coverage — they will not allow liability-only because they have a financial stake in the vehicle. Dropping to liability-only on a financed car violates your loan agreement and can result in the lender buying insurance on your behalf and charging you for it, often at a much higher rate.

Liability-only also makes sense if you have other assets to protect. If you own a home or have savings, carrying only the state minimum exposes those assets in a lawsuit. Someone you seriously injure could sue you for damages beyond your insurance limits. Carrying higher liability limits (50/100/50 or 100/300/100) costs only $10 to $20 more per month than the state minimum and protects your assets far better. Many people with older cars choose higher liability limits and skip collision coverage as a middle ground.

How to find the lowest liability-only rates

The same factors that affect any car insurance quote affect liability-only rates: your age, gender, marital status, driving record, the vehicle, annual mileage, where you park the car, and your credit score in most states. You cannot change most of these, but you can shop around.

Get quotes from at least three insurers — major national companies like State Farm, Geico, and Progressive, plus regional or direct insurers in your state. Each company weights risk factors differently, so the cheapest option for a 25-year-old with one ticket might be different from the cheapest for a 60-year-old with a clean record. Online quote tools take 5 to 10 minutes and do not require you to buy anything.

When you get quotes, make sure they are all for the same coverage limits. Comparing a 15/30/5 quote to a 50/100/50 quote tells you nothing useful. Ask each company about discounts: bundling home and auto insurance, paying in full upfront, maintaining continuous coverage, completing a defensive driving course, or having safety features in your car can each lower your rate by 5 to 15 percent.

What happens if you cause an accident with liability-only

You report the accident to your insurer. The insurer investigates, determines fault, and if you are found liable, they pay the other party's medical bills, vehicle repairs, and other damages up to your policy limits. You pay your deductible only if you have collision or comprehensive coverage — liability-only has no deductible because the insurer is not paying for your car.

If the damages exceed your liability limits, you are responsible for the difference. If you caused $75,000 in injury and property damage but your policy limit is 50/100/50, you owe $25,000 out of pocket. The other party can sue you to recover it, and if they win, they can garnish your wages or place a lien on your home depending on your state's laws.

If you cause an accident and have no insurance at all, the consequences are far worse: license suspension, fines, possible jail time, and a civil judgment against you. Liability-only is the legal minimum for a reason — it protects the other party and keeps you out of legal trouble, even if it does not protect your own vehicle.

Liability-only versus adding collision coverage

The choice between liability-only and liability plus collision comes down to the value of your car and how much you can afford to lose. Collision coverage pays to repair or replace your car after an accident, regardless of fault. You pay a deductible (usually $500 or $1,000) and the insurer covers the rest, up to the car's actual cash value.

If your car is worth $8,000 and collision coverage costs $40 per month, you break even after about 16 years of payments with no claims. If you keep the car for 5 years, you pay $2,400 for coverage that may never pay out. But if you cause an accident in year 2, collision coverage saves you $7,500 (minus your deductible). The risk tolerance is personal — some drivers sleep better knowing they are covered; others prefer to self-insure and pocket the savings.

A middle option is to carry collision coverage with a higher deductible ($1,000 instead of $500), which lowers your monthly premium. This reduces your out-of-pocket cost if you have a claim but keeps your monthly payments lower than full coverage with a low deductible.

Frequently Asked Questions

Can I legally drive with just liability insurance?

Yes, liability-only meets the legal minimum in all 50 states. However, if you financed or leased your car, your lender requires collision and comprehensive coverage as a condition of the loan or lease. Driving with only liability when you owe money on the car violates your agreement with the lender.

What if someone hits me and I have liability-only?

If the other driver is at fault, their liability insurance pays for your repairs. If they have no insurance or insufficient coverage, your uninsured or underinsured motorist coverage pays (if you have it). With liability-only and no other coverage, you pay for your own repairs out of pocket, even if the accident was not your fault.

Does liability-only cover theft or weather damage?

No. Liability-only covers only damage you cause to someone else. Theft, vandalism, hail, flooding, and fire are covered by comprehensive insurance, which you would need to add separately. If your car is stolen and you have only liability, you lose the car and the insurer pays nothing.

How much liability coverage should I carry if I go above the state minimum?

Most insurance agents recommend at least 100/300/100 if you have any assets to protect. The difference in cost between the state minimum and 100/300/100 is usually $10 to $25 per month, but it protects you from a lawsuit that could take your home or wages. If you have significant savings or own property, consider 250/500/250 or higher.

Will my rate go up if I switch from full coverage to liability-only?

No, your rate will go down because you are removing coverage, not adding it. However, if you later add collision coverage back, your rate will increase. Some insurers offer a small discount for continuous coverage, so dropping and re-adding coverage over time may cost more than keeping it steady.
