When Car Insurance Is Required and When It's Your Choice

Most states require car insurance if you own or drive a car

Whether you need car insurance depends on where you live and how you use your vehicle. In most U.S. states, you must carry liability insurance — the type that pays for damage or injuries you cause to someone else — if you own a car or drive one regularly. A few states allow you to post a cash bond or self-insure instead, but liability coverage is the legal minimum almost everywhere.

The specific amount you must carry varies by state. Some states require as little as $15,000 in bodily injury coverage per person, while others require $50,000 or more. Your state's Department of Motor Vehicles or Insurance Commissioner publishes the exact minimums for your area.

If you financed or leased your car, your lender or leasing company will require you to carry comprehensive and collision coverage in addition to liability. These cover damage to your own vehicle from accidents, theft, or weather — not just damage you cause to others.

Key Takeaways

• Liability insurance is legally required in nearly all states if you own or regularly drive a car.
• Your state sets the minimum coverage amounts, which range from roughly $15,000 to $50,000 depending on where you live.
• If you financed or leased your vehicle, the lender requires comprehensive and collision coverage on top of liability.
• Driving without insurance where it is required can result in license suspension, fines, and civil liability if you cause an accident.
• If you own a car outright and your state allows it, you may legally choose not to carry coverage, though this puts your own assets at risk.

What happens if you drive without required insurance

Driving without insurance in a state that requires it is a violation. The penalties vary, but most states will suspend your driver's license, issue fines ranging from a few hundred to several thousand dollars, and may require you to file an SR-22 form — a certificate proving you have insurance — before you can legally drive again.

Beyond legal penalties, if you cause an accident without insurance, you are personally responsible for all damages. A court can order you to pay medical bills, vehicle repairs, lost wages, and other costs out of your own pocket. If you cannot pay, the injured party may pursue wage garnishment or place a lien on your property.

Insurance companies also track uninsured driving. If you later buy insurance, the company may charge higher rates or deny your claim if they discover you drove uninsured during a gap in coverage.

States that allow alternatives to traditional insurance

A small number of states — currently New Hampshire, Virginia, and Mississippi — do not require liability insurance if you own a car. However, even in these states, if you cause an accident, you must prove you can pay for damages. New Hampshire and Virginia allow you to post a cash bond with the state instead. Mississippi requires you to register as a self-insured driver and prove financial responsibility.

Even where insurance is not legally required, most people carry it because the financial risk of an accident is high. A single serious accident can cost tens of thousands of dollars in medical care and vehicle damage. Without insurance, you would pay all of that yourself.

Financed and leased vehicles always require full coverage

If you borrowed money to buy your car or leased it, the lender or leasing company has a financial interest in the vehicle. They will require you to carry comprehensive coverage (which covers theft, weather, and vandalism) and collision coverage (which covers accidents), in addition to the state-required liability insurance.

These requirements are written into your loan or lease agreement. The lender can repossess your vehicle if you let this coverage lapse, even if you continue making payments. Many lenders monitor your insurance status and will contact you if your policy lapses.

Once you pay off your car loan or your lease ends, you regain the choice to carry only liability insurance (or nothing, in the few states that allow it). However, most financial advisors recommend keeping comprehensive and collision coverage if your car is worth more than a few thousand dollars, because you would have to replace it entirely out of pocket if it were damaged or stolen.

What minimum liability coverage actually covers

Liability insurance pays for injuries and property damage you cause to other people or their property. If you hit another car, liability pays for their medical bills and vehicle repairs. If you hit a pedestrian, it covers their medical costs. If you damage someone's fence or mailbox, liability covers that too.

Liability does not cover damage to your own vehicle, your own medical bills, or your own lost wages — even if you caused the accident. That is why many people carry additional coverage like collision, comprehensive, and uninsured motorist protection.

The state minimum is often too low to cover a serious accident. A major injury can cost $100,000 or more in medical care alone. Many insurance companies recommend carrying limits of at least $100,000 per person and $300,000 per accident, which is higher than the state minimum in most places.

Situations where you might not need insurance

If you own a car outright and live in one of the few states that do not require insurance, you can legally choose not to carry it. However, this is uncommon and risky. Most people in this situation still buy at least liability coverage because the cost of an accident is so high.

If you own a car but do not drive it — for example, a classic car you keep in storage — you may not need full coverage. Some insurance companies offer storage or collector car policies that cost less than standard coverage. You would still need liability if you ever drive it on public roads.

If you use a car-sharing service like Zipcar or Turo, the company's insurance covers you while you are using their vehicle. You do not need your own policy for that use. However, if you own a personal vehicle, you still need insurance for it.

How to find your state's insurance requirements

Your state's Department of Motor Vehicles website lists the minimum liability coverage amounts required in your state. You can also contact your state's Insurance Commissioner's office, which regulates insurance companies and can answer questions about what you are required to carry.

When you buy insurance, the agent or online form will ask you to confirm you understand your state's minimums. Most people choose to carry more than the minimum because the cost difference is small and the protection is much greater.

If you are unsure whether your situation requires insurance — for example, if you recently moved or inherited a vehicle — contact your state's DMV directly. They can tell you exactly what is required based on how you plan to use the car.

Frequently Asked Questions

Can I drive someone else's car without my own insurance?

In most cases, yes — the car owner's insurance covers you while you drive with their permission. However, some policies exclude certain drivers or situations. Before you drive someone else's car, ask the owner to confirm their insurance will cover you. If you regularly borrow the same car, you should be listed as an authorized driver on that policy.

What if I only drive my car occasionally?

You still need insurance in most states, even if you drive infrequently. Some insurance companies offer low-mileage discounts if you drive fewer than a certain number of miles per year. If you truly do not drive the car, you may be able to suspend your policy temporarily, but you cannot legally drive without active coverage.

Do I need insurance if I have a learner's permit?

Yes. A learner's permit allows you to drive, so you need insurance. You are typically covered under a parent's or guardian's policy while you practice, but confirm this with the insurance company. Once you get your license, you should be listed as a driver on the policy.

What is an SR-22 and when do I need one?

An SR-22 is a form your insurance company files with your state to prove you have coverage. You need one if you were caught driving uninsured, had a serious violation, or had your license suspended. It is not a type of insurance — it is just proof that your existing policy meets state requirements. You typically need to maintain it for three years.

Can I be insured on two different cars at the same time?

Yes. If you own multiple vehicles, you can have one policy that covers all of them, or separate policies for each. Most people use one policy for simplicity and cost savings. You do not need separate insurance for each car — one policy can list multiple vehicles.
