Car insurance is required by law in every state, but the type and amount depend on where you live and how you use your vehicle

Every state except New Hampshire requires you to carry some form of auto insurance before you drive on public roads. New Hampshire lets uninsured drivers operate vehicles if they post a bond or prove they can pay for damages, but this is the only exception in the country. The specific coverage types and minimum dollar amounts vary by state — what satisfies the law in one state may not in another.

If you finance or lease a car, your lender will require comprehensive and collision coverage on top of the state minimum. If you own your car outright, you only need to meet your state's minimum liability requirements, though most financial advisors recommend more coverage than the legal minimum.

Key Takeaways

  • Every state except New Hampshire requires liability insurance before you drive on public roads, with minimum coverage amounts set by state law.
  • Liability insurance covers damage you cause to other people's property or injuries you cause to other people — not damage to your own vehicle.
  • If you have a car loan or lease, your lender will require comprehensive and collision coverage in addition to liability insurance.
  • Driving without the insurance your state requires can result in license suspension, vehicle impoundment, fines, and legal liability if you cause an accident.
  • Uninsured motorist coverage protects you if someone without insurance hits you, and is required or strongly recommended in most states.

What your state's minimum liability insurance covers

Liability insurance pays for damage or injuries you cause to someone else. It does not cover damage to your own car or injuries to yourself. Every state sets a minimum amount you must carry, written as three numbers — for example, 25/50/25. The first number is the per-person limit for bodily injury, the second is the total limit for all people injured in one accident, and the third is the limit for property damage.

These minimums are often too low to protect you if you cause a serious accident. A single injury requiring surgery or long-term care can easily exceed your state's per-person limit, leaving you personally responsible for the rest. That is why most insurance agents recommend carrying higher limits than the legal minimum — often 100/300/100 or more.

When you must carry comprehensive and collision coverage

Comprehensive coverage pays for damage to your car from theft, weather, vandalism, or hitting an animal. Collision coverage pays for damage from hitting another vehicle or object. If you have a loan on your car, your lender's contract requires you to carry both of these coverages until the loan is paid off. The same applies if you lease — the leasing company will require them as a condition of the lease agreement.

If you own your car outright with no loan, you are not legally required to carry comprehensive or collision coverage. However, if your car is newer or still has significant value, losing it to theft or an accident without this coverage means you absorb the entire loss yourself. The decision depends on how much you could afford to replace or repair your vehicle.

What happens if you drive without required insurance

Driving without the insurance your state requires is a violation that carries real consequences. Most states will suspend your driver's license, impound your vehicle, and issue fines ranging from a few hundred to several thousand dollars depending on the state and whether it is a repeat offense. Some states also require you to file an SR-22 form (a certificate of financial responsibility) for several years after a violation, which increases your insurance costs significantly.

If you cause an accident while uninsured, you are personally liable for all damages — medical bills, vehicle repairs, lost wages, and legal fees. A lawsuit can follow you for years and result in wage garnishment or liens on your property. The financial risk of driving uninsured far exceeds the cost of carrying the minimum coverage your state requires.

Uninsured and underinsured motorist coverage

Uninsured motorist coverage protects you if someone without insurance hits you and causes injury or damage. Underinsured motorist coverage kicks in when the at-fault driver's insurance limits are too low to cover your damages. Many states require you to carry uninsured motorist coverage or allow you to decline it in writing. Even where it is optional, most insurance agents recommend it because roughly one in eight drivers on the road is uninsured.

This coverage is relatively inexpensive and protects you from a gap in the system — you did everything right by carrying insurance, but someone else did not, and you should not bear the cost. If you decline it, make sure you understand what you are giving up and that you have other resources to cover a serious accident.

How to find out your state's specific requirements

Your state's insurance commissioner or department of motor vehicles publishes the exact minimum coverage amounts required. You can find this information on your state's DMV website or by calling your local DMV office. Your insurance agent can also tell you what your state requires and help you understand the difference between the legal minimum and what you actually need based on your situation.

When you get a quote from an insurance company, they will ask what state you live in and automatically show you options that meet your state's minimum requirements. You can then choose to carry more coverage if you want additional protection. Comparing quotes from multiple insurers is the best way to find the coverage you need at a price you can afford.

Frequently Asked Questions

Can I get a ticket for having expired insurance even if I have coverage now?

Yes. If you are pulled over and your insurance card or policy shows a lapsed coverage period, you can receive a ticket for driving uninsured during that time, even if you have active coverage at the moment of the stop. Keep your current insurance card in your vehicle and renew your policy before it expires.

What if I only drive my car occasionally or keep it parked most of the time?

You still need insurance if the car is registered and you drive it on public roads at all. Some insurers offer low-mileage or usage-based policies that cost less if you drive infrequently, but you cannot legally skip insurance. If you do not plan to drive the car, you can request that your state suspend the registration, which removes the insurance requirement temporarily.

Does my parents' insurance cover me if I drive their car?

Usually yes, if you live in their household and are listed as a driver on their policy. However, if you live separately or are not listed, you may not be covered. Check with your parents' insurance agent to confirm you are covered before driving their vehicle regularly.

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

An SR-22 is a certificate your insurance company files with your state's DMV to prove you are carrying the required coverage. You need one if you have been convicted of driving uninsured, received multiple traffic violations, or had a DUI. It is not extra insurance — it is just proof to the state that you have coverage. The filing fee is usually $15 to $25.
