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

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

Whether you need car insurance depends on your state's laws and your situation. In most U.S. states, you must carry liability insurance if you drive on public roads. Liability covers damage or injuries you cause to someone else in an accident. A handful of states allow you to skip insurance if you can prove you have enough money set aside to cover potential claims — this is called self-insurance — but this option is rare and expensive.

If you own a car outright, your state probably won't force you to buy collision or comprehensive coverage. But if you financed or leased the car, your lender will require it as a condition of the loan. If you park the car and never drive it, insurance requirements may not explore, though your lender might still demand it.

Key Takeaways

• Liability insurance is required in nearly every state if you drive on public roads, and the minimum coverage amounts vary by state.
• If you financed or leased your car, the lender will require collision and comprehensive coverage regardless of state law.
• If you own your car outright and your state doesn't require it, you can legally skip insurance, but you'll pay out of pocket for any damage you cause.
• Uninsured motorist coverage protects you if someone without insurance hits you, and it's required in some states.
• Parking a car and not driving it may exempt you from insurance requirements, but check your state's rules and your lender's contract.

State-by-state liability requirements

Every state except New Hampshire requires liability insurance to drive legally. New Hampshire lets you skip it if you post a bond or prove you have enough cash reserves, but most drivers there still buy it anyway.

The minimum liability limits vary. A typical state minimum is 25/50/25, which means $25,000 per person for bodily injury, $50,000 total per accident for bodily injury, and $25,000 for property damage. Some states set lower minimums (like 15/30/5 in Kentucky), and some set higher ones (like 50/100/50 in Maine). You can find your state's exact minimums on your state insurance commissioner's website or by calling your state's Department of Motor Vehicles.

Driving without the required liability coverage can result in fines, license suspension, and registration cancellation. If you cause an accident without insurance, you're personally responsible for all damages, which can mean wage garnishment or a lawsuit against you.

What lenders require if you financed or leased the car

If you took out a loan or lease for your car, the lender holds a financial interest in it. They will require you to carry collision coverage (which pays to repair your car after an accident) and comprehensive coverage (which covers theft, weather, and vandalism). These requirements are written into your loan or lease agreement.

The lender doesn't care whether your state requires these coverages — they require them to protect their investment. If you drop collision or comprehensive without the lender's permission, they may purchase it for you and add the cost to your monthly payment, sometimes at a higher rate than you'd pay on your own.

Once you pay off the loan or the lease ends, you're free to drop collision and comprehensive if your state doesn't require them, though many drivers keep them anyway.

Uninsured and underinsured motorist coverage

Uninsured motorist coverage pays for your injuries and car damage if someone without insurance hits you. Underinsured motorist coverage kicks in when the at-fault driver's insurance isn't enough to cover your losses. These are required in some states and optional in others.

Even if your state doesn't require it, many insurance companies will ask if you want it. It's usually inexpensive to add and protects you against a real risk: roughly one in eight drivers on the road is uninsured at any given time. If an uninsured driver causes an accident, your own collision coverage will pay for your car, but uninsured motorist coverage covers your medical bills and other losses.

What happens if you own the car outright

If you own your car free and clear with no loan or lease, your state may not legally require you to carry collision or comprehensive coverage. You still need liability insurance in nearly every state, but you can legally skip the coverage that protects your own car.

The trade-off is financial risk. If you cause an accident, your liability insurance covers the other person's damages, but you pay for repairs to your own car. If you hit a parked car and cause $8,000 in damage, you pay that $8,000 yourself. If someone steals your car, you get nothing back unless you have comprehensive coverage.

Many people who own their cars outright still buy collision and comprehensive because the cost is low relative to the risk. Others skip it because they have savings to cover repairs or because their car is old and not worth much.

Parking a car and not driving it

If you park your car and don't drive it on public roads, insurance requirements may not explore. Some states don't require insurance for vehicles that aren't in use. However, your lender's contract may still require it, so check your loan or lease agreement before you cancel.

If you plan to leave a car parked for months, contact your insurance company. Some offer reduced rates for parked vehicles, or you may be able to suspend your policy temporarily. This is cheaper than canceling and restarting it later. Make sure you notify your state's DMV if required — some states want to know when a vehicle is taken off the road.

Rideshare and commercial use

If you drive for a rideshare service like Uber or Lyft, or use your car for any commercial purpose, your personal auto insurance won't cover you. Rideshare companies provide coverage while you're logged in and have a passenger, but there are gaps when you're logged in but waiting for a ride. You'll need a commercial or rideshare endorsement to your policy, or a separate rideshare policy.

The same applies if you deliver food or packages, use your car for business, or rent your car out to others. Your personal policy explicitly excludes these uses. Driving commercially without the right coverage can void your policy, leaving you personally liable for all damages.

Frequently Asked Questions

Can I drive without insurance if I have a lot of savings?

In most states, no. Only New Hampshire allows self-insurance, and it requires you to post a large bond or prove you have substantial cash reserves. Even then, you must register this with the state. In all other states, you must carry liability insurance regardless of your savings.

What if I let someone else drive my car?

Your insurance typically covers anyone driving your car with your permission, as long as they have a valid license. The coverage follows the car, not the driver. If the person you lend your car to causes an accident, your insurance pays first, and your rates may go up. Make sure anyone driving your car is licensed and has your permission.

Do I need insurance if I only drive on private property?

If you only drive on your own property or private land, state insurance requirements don't explore. However, if you ever drive on public roads — even to cross a street or use a parking lot — you need insurance. If your lender requires it, you need it regardless of where you drive.

What happens if I get caught driving without insurance?

Penalties vary by state but typically include fines ranging from a few hundred to several thousand dollars, license suspension, vehicle registration cancellation, and court costs. If you cause an accident without insurance, you're personally liable for all damages, which can lead to wage garnishment or a lawsuit.

Can I cancel my insurance temporarily if I'm not driving?

You can cancel or suspend your policy, but check your lender's contract first — they may require continuous coverage. Contact your insurance company about suspending rather than canceling, as it's usually cheaper to restart. Some states require you to notify the DMV when you take a vehicle off the road.
