Most states require car insurance, but the rules depend on where you live and how you use your vehicle

Whether you must carry car insurance depends on your state's laws and whether you own or finance your car. Every state except New Hampshire requires drivers to carry liability insurance — the coverage that pays for damage or injuries you cause to someone else. If you finance or lease a vehicle, your lender will require comprehensive and collision coverage as a condition of the loan. If you own your car outright and drive it on public roads, your state almost certainly requires liability coverage at minimum.

The specific amounts vary by state. Most states set a minimum liability limit — for example, $25,000 per person and $50,000 per accident in many places — but some require higher amounts. Driving without the coverage your state requires is illegal and can result in fines, license suspension, or both.

Key Takeaways

  • Every state except New Hampshire requires liability insurance if you drive on public roads, though the minimum coverage amounts vary by state.
  • If you have a car loan or lease, your lender requires comprehensive and collision coverage in addition to liability, regardless of state law.
  • Driving without required insurance can result in fines, license suspension, and civil liability if you cause an accident.
  • If you own your car outright and do not drive it on public roads, you may not be legally required to insure it, but this varies by state.
  • Some states offer low-income insurance programs or allow you to deposit money with the state instead of buying a policy.

What liability insurance covers and why states require it

Liability insurance pays for injuries or property damage you cause to someone else in an accident. It does not cover damage to your own vehicle. If you hit another car, a person, or property, your liability coverage pays their medical bills, vehicle repairs, or other losses up to your policy limit. This is why states require it — to ensure that if you cause an accident, the other person has a way to recover their losses instead of suing you directly.

The minimum liability limits your state sets are usually low enough that a serious accident can exceed them. If you cause $100,000 in damage but your state's minimum is $25,000, you are personally responsible for the remaining $75,000. For this reason, many insurance agents recommend carrying higher limits than your state requires, even though you are not legally obligated to do so.

When your lender requires more than state law

If you finance or lease a car, your lender has a financial stake in the vehicle and will require you to carry comprehensive and collision coverage in addition to liability. Comprehensive covers theft, weather, vandalism, and other non-accident damage. Collision covers damage from accidents, regardless of who is at fault. These coverages protect the lender's investment if the car is damaged or totaled.

Your lender will specify the deductible amounts and minimum coverage limits in your loan agreement. You cannot legally register or drive the financed vehicle without proof of these coverages. If you let your insurance lapse, the lender may purchase insurance on your behalf and add the cost to your loan payment — a practice called force-placed insurance, which is usually more expensive than buying it yourself.

States with different or lower requirements

New Hampshire is the only state with no mandatory insurance requirement for drivers. However, even in New Hampshire, if you cause an accident and cannot pay for damages, you can lose your license and face other penalties. Most New Hampshire drivers still carry insurance because the financial risk of an accident is too high.

A few states allow you to meet the insurance requirement through other means. Some let you deposit a large sum of money with the state — typically $35,000 to $50,000 — as proof you can cover damages. Others accept a surety bond. These alternatives are rarely practical for most drivers, but they exist in states like Florida, Georgia, and South Carolina.

What happens if you drive without required insurance

Driving without liability insurance where it is required is a criminal offense in most states. Penalties typically include fines ranging from a few hundred to several thousand dollars, depending on the state and whether it is your first offense. Your driver's license can be suspended, and your vehicle registration can be revoked. Some states require you to file an SR-22 form — a certificate of financial responsibility — before you can reinstate your license, and you must maintain continuous coverage for a set period, usually three years.

If you cause an accident while uninsured, you are personally liable for all damages. The other driver can sue you for medical bills, lost wages, vehicle repairs, and pain and suffering. A judgment against you can result in wage garnishment or liens on your property. Additionally, you may face criminal charges if anyone is injured.

Options if you cannot afford standard insurance

Some states operate low-income auto insurance programs that offer reduced-rate policies to drivers who meet income requirements. These programs are sometimes called FAIR plans or assigned risk pools. Your state's insurance commissioner's office or department of motor vehicles can tell you whether such a program exists in your state and how to access it.

You can also lower your premium by increasing your deductible, dropping optional coverages like comprehensive and collision if you own your car outright, or asking about discounts for bundling home and auto policies, completing a defensive driving course, or maintaining a clean driving record. Some insurers offer usage-based programs that monitor your driving habits and reduce your rate if you drive safely.

Vehicles that may not require insurance

If you own a vehicle outright and do not drive it on public roads — for example, a car you keep on private property or use only for off-road purposes — your state may not require you to insure it. However, the rules vary. Some states require insurance for any registered vehicle, even if it is not driven. Others only require it for vehicles actively driven on public roads. Check your state's motor vehicle laws or contact your state's insurance commissioner to know for certain.

If you store a vehicle for an extended period, some insurers offer storage or laid-up coverage at a reduced rate. This protects the vehicle while it is not in use but typically does not cover liability if someone is injured on or by the vehicle.

Frequently Asked Questions

Can I drive someone else's car if I do not have insurance?

In most cases, no. If you cause an accident, the car owner's insurance may cover it, but only if you had permission to drive the vehicle. However, you are still driving illegally if your state requires all drivers to carry insurance. The owner's policy may deny the claim if the driver was uninsured, leaving both of you liable. It is safer and legal to be listed as a driver on the policy or to have your own coverage.

What if I only drive my car occasionally?

You still need insurance if you drive on public roads, even occasionally. However, some insurers offer low-mileage or usage-based policies that charge based on how much you actually drive. These can be cheaper than standard policies if you drive infrequently. You must maintain continuous coverage — letting your policy lapse and then restarting it can trigger license suspension in some states.

Do I need insurance if I have a suspended license?

You should not be driving at all with a suspended license. However, if you are required to file an SR-22 to reinstate your license, you must maintain continuous insurance during that period. If you are caught driving on a suspended license without insurance, penalties are more severe than either violation alone.

What is the difference between being uninsured and underinsured?

Uninsured means you have no liability coverage. Underinsured means you have liability coverage, but your policy limits are too low to cover the damages you caused. If you are underinsured, you are personally responsible for the difference. This is why carrying higher limits than your state's minimum is often recommended.

Can I get a refund if I cancel my insurance mid-policy?

Most insurers refund the unused portion of your premium if you cancel, though some charge a cancellation fee. However, canceling your policy creates a gap in coverage, which can trigger license suspension and require you to file an SR-22 when you reinstate. If you need to stop driving, it is better to suspend your policy temporarily or switch to a lower-cost option than to cancel entirely.
