Liability insurance pays for damage or injury you cause to someone else

Liability insurance covers the medical bills, vehicle repairs, and other losses of the other person when you are at fault in a car accident. It does not cover your own injuries or your own vehicle. Most states require you to carry it, and your lender will require it if you have a loan or lease on your car.

Liability has two parts: bodily injury liability, which covers medical expenses and lost wages for people you injure, and property damage liability, which covers the other person's vehicle and other property like fences or buildings. You choose how much coverage you want in each category, and higher limits cost more per month but protect you from larger out-of-pocket costs if you cause a serious accident.

Key Takeaways

  • Liability insurance pays for injuries and property damage you cause to others, not damage to your own car or body.
  • Most states legally require liability coverage, and your lender will require it if you financed or leased your vehicle.
  • You choose your coverage limits (for example, $25,000 per person or $50,000 per accident), and higher limits mean higher monthly premiums.
  • If you cause an accident and your liability limit is too low, you can be sued personally for the difference and face wage garnishment or asset seizure.

Bodily injury liability covers medical costs and lost income

Bodily injury liability pays for hospital bills, surgery, physical therapy, and other medical treatment for people you injure in an accident. It also covers lost wages if someone cannot work while recovering, and in some cases pain and suffering damages awarded by a court.

Coverage limits are written as two numbers, like 25/50 or 100/300. The first number is the maximum paid per injured person; the second is the maximum paid per accident regardless of how many people are hurt. A 25/50 limit means your insurance will pay up to $25,000 for one person's injuries and up to $50,000 total if multiple people are hurt in the same crash. If medical bills exceed your limit, the injured person can sue you personally for the remainder.

Property damage liability covers the other vehicle and other structures

Property damage liability pays to repair or replace the other person's vehicle after an accident you cause. It also covers damage to property like mailboxes, fences, storefronts, or utility poles that you hit.

Property damage limits are a single number, such as $25,000 or $50,000, representing the maximum your insurance will pay per accident. If you cause $60,000 in damage to an expensive vehicle and your limit is $25,000, your insurance pays $25,000 and you are responsible for the remaining $35,000. The other person's insurance company or their attorney can pursue you for that amount through a lawsuit.

State minimum requirements vary, but are often lower than recommended

Every state that requires liability insurance sets a legal minimum. Common minimums are 15/30/5 (meaning $15,000 bodily injury per person, $30,000 per accident, and $5,000 property damage) or 25/50/25, but these vary by state. You can look up your state's requirement through your state's insurance commissioner's office or your insurance agent.

Meeting the legal minimum protects you from fines and license suspension, but it often leaves you exposed to personal liability. A serious injury accident can easily generate $100,000 or more in medical costs. Insurance industry groups and financial advisors typically recommend limits of at least 100/300/100, and higher if you have significant assets to protect.

What happens if your liability limit is too low

If you cause an accident and the damages exceed your liability limit, the injured person or their insurance company can sue you personally for the difference. A court judgment can result in wage garnishment, where a portion of your paycheck goes to the injured party, or a lien against your home or other assets.

This is why coverage limits matter more than the monthly premium difference. Raising your limit from 25/50 to 100/300 typically costs $10 to $30 more per month, but protects you from potentially losing your home or having your wages garnished for years. Once a judgment is entered, it can follow you for a decade or longer depending on your state.

Liability does not cover your own injuries or vehicle damage

Liability insurance is one-directional: it protects the other person, not you. If you are injured in an accident you cause, your own medical bills are not covered by your liability policy. If your car is damaged, liability does not pay for repairs.

To cover your own injuries, you need medical payments coverage (also called med pay), which is optional and pays your medical bills regardless of who caused the accident. To cover damage to your own vehicle, you need collision coverage (for accidents) or comprehensive coverage (for theft, weather, and other non-collision damage). These are separate policies you purchase in addition to liability.

Umbrella insurance provides extra protection beyond your liability limits

If you have significant assets or are concerned about a lawsuit exceeding your liability limits, you can purchase umbrella insurance, which adds an extra layer of coverage on top of your car insurance. A typical umbrella policy might provide $1 million in additional coverage and costs $150 to $300 per year.

Umbrella insurance kicks in only after your car insurance liability limit is exhausted. For example, if you cause a $500,000 accident, your car insurance pays up to your limit (say, $100,000), and your umbrella policy covers the remaining $400,000. Umbrella policies also cover liability claims from other situations, like someone injured on your property, making them useful beyond just car accidents.

Frequently Asked Questions

Does liability insurance cover me if I lend my car to a friend?

Yes, liability coverage follows the vehicle, not the driver. If your friend causes an accident while driving your car, your liability insurance pays for the other person's damages. Your friend's insurance is secondary. However, if your friend lives with you or regularly borrows your car, tell your insurance company, as this can affect your rate.

What if the other driver is at fault but I don't have liability insurance?

Their liability insurance should pay for your damages, but you will need to file a claim with their insurer. If they are uninsured or underinsured, you will need your own uninsured/underinsured motorist coverage to recover damages. Driving without liability insurance is illegal in most states and can result in fines, license suspension, and court-ordered SR-22 filing.

Can I be sued even if my liability insurance pays the full claim?

No. Once your insurance company pays the claim up to your policy limit, the injured person cannot pursue you further for that accident in most cases. However, if damages exceed your limit, they can sue you personally for the remainder. This is why adequate coverage limits matter.

Do I need liability insurance if I own my car outright?

It is not required by your lender if you own the car, but it is required by state law in most places. Driving without it is illegal and exposes you to personal liability if you cause an accident. Even if your state does not require it, the financial risk of a lawsuit makes it worth carrying.
