Car insurance is mandatory in every state, but the rules about what type and how much vary by where you live
Every state except New Hampshire requires you to carry auto insurance before you drive on public roads. New Hampshire allows uninsured driving if you post a bond or prove you can pay for damages yourself, but this is the only exception in the country. The type of coverage required and the minimum dollar amounts differ from state to state, and some states have additional rules about proof of insurance and when coverage must start.
Driving without the insurance your state requires is illegal. You can face fines, license suspension, vehicle registration suspension, and in some cases jail time. If you cause an accident without insurance, you become personally liable for all damages — medical bills, vehicle repairs, lost wages — which can follow you for years through wage garnishment or lawsuits.
Key Takeaways
- Every state except New Hampshire requires some form of auto insurance before you drive legally on public roads.
- Minimum coverage amounts vary by state; your state's Department of Motor Vehicles website lists the exact requirements for your location.
- Proof of insurance must be in your vehicle at all times, and you may need to show it when you register your car or renew your registration.
- Driving without required insurance can result in fines, license suspension, and personal liability for accident damages that can last years.
- Some states require continuous coverage; gaps in insurance can trigger license suspension even if you were not driving during the gap.
What types of coverage are required by law
Most states require liability insurance, which pays for damage or injury you cause to someone else. This is the foundation of mandatory coverage in nearly every state. Liability has two parts: bodily injury liability (covers medical bills and lost wages for people you injure) and property damage liability (covers damage to other people's vehicles and property).
Some states also require uninsured motorist coverage, which protects you if someone without insurance hits you. A smaller number of states require underinsured motorist coverage, which covers you when the at-fault driver's insurance is not enough to pay your damages. A few states require personal injury protection (PIP) or medical payments coverage, which pays your own medical bills regardless of who caused the accident.
Collision and comprehensive coverage — which pay for damage to your own vehicle from accidents, theft, or weather — are not required by law in any state. However, if you have a car loan or lease, your lender will require you to carry both as a condition of financing.
Minimum coverage amounts by state
States set their own minimum dollar amounts for liability coverage. These minimums are typically expressed as three numbers: bodily injury per person, bodily injury per accident, and property damage per accident. For example, a state might require 25/50/25, meaning $25,000 per person injured, $50,000 total per accident, and $25,000 for property damage.
The lowest minimums in the country are around 15/30/5 (15 thousand per person, 30 thousand per accident, 5 thousand property damage). The highest are around 50/100/50. Your state's Department of Motor Vehicles website lists the exact minimums for your location. These minimums are often too low to cover serious accidents; many people buy higher limits to protect themselves.
Proof of insurance and registration
You must carry proof of insurance in your vehicle at all times. This is usually your insurance card or a digital copy on your phone. If a police officer stops you, you must show proof of current insurance. Failure to produce it can result in a ticket even if you actually have insurance.
When you register your vehicle or renew your registration, most states require you to show proof of insurance. Some states electronically verify coverage through their insurance companies, so your insurer reports directly to the state that you are covered. If your coverage lapses, the state's system may flag it and suspend your registration or license automatically.
What happens if you drive without insurance
Driving without required insurance is a criminal offense in most states. First-time penalties typically include fines ranging from a few hundred to several thousand dollars, depending on the state. Your driver's license can be suspended, and your vehicle registration can be suspended or revoked. Some states require you to file an SR-22 form (a certificate of financial responsibility) with the state for several years after an uninsured driving conviction, which increases your insurance costs significantly.
If you cause an accident while uninsured, you are personally responsible for all damages. This means the other driver can sue you directly for medical bills, vehicle repairs, lost wages, and pain and suffering. A judgment against you can result in wage garnishment, bank account levies, and a lien on your property. These consequences can follow you for years or even decades depending on your state's statute of limitations.
Gaps in coverage and continuous insurance requirements
Some states have continuous insurance requirements, which means you cannot have any gap in coverage, even if you are not driving. If your policy lapses for even one day, the state may suspend your license or registration. This applies even if you were parked at home and did not drive during the gap.
If you let your insurance lapse, you typically must file an SR-22 form to reinstate your license or registration. The SR-22 is not insurance itself — it is a form your insurance company files with the state certifying that you now have coverage. You will need to maintain continuous coverage for the period the state requires, usually three years, or face another suspension.
Insurance requirements for different situations
If you own a vehicle but do not drive it, you may still need to carry insurance in some states. Check your state's rules; some allow you to keep a vehicle uninsured if it is not registered or if you file a non-operation declaration. If you are financing or leasing a vehicle, your lender requires insurance regardless of state law, and the lender is usually named on the policy as a loss payee.
If you are a new driver or have a suspended license, insurance requirements do not change — you still need the same coverage your state requires. However, you cannot legally drive until your license is reinstated. Some people buy insurance before their license is reinstated so they can drive immediately once it is valid, but this is optional.
How to find your state's specific requirements
Your state's Department of Motor Vehicles website lists the exact insurance requirements for your location, including minimum coverage amounts, what types of coverage are required, and what documents you need to show when registering your vehicle. You can also call your state's DMV directly or visit a local office.
When you get a quote from an insurance company, the agent will tell you what your state requires and can help you understand the difference between minimum coverage and higher limits. It is worth comparing quotes from multiple insurers, as rates vary significantly even for the same coverage.
Frequently Asked Questions
What happens if I get pulled over and do not have my insurance card?
You can receive a ticket for not having proof of insurance, even if you actually have a policy. However, many states allow you to show proof later in court or to the police department, which can result in the ticket being dismissed. Check your ticket for instructions on how to resolve it in your state.
Can I drive someone else's car if I do not have insurance?
No. You are required to have your own insurance policy or be listed as a driver on someone else's policy. Driving without being insured or listed on a policy is illegal. If you regularly borrow a car, ask the owner to add you to their policy or get your own.
What if I cannot afford insurance?
Some states offer low-income insurance programs or assigned risk pools that provide coverage at lower rates. Contact your state's Department of Insurance or Department of Motor Vehicles to learn what programs are available. You can also shop around — rates vary widely between insurers, and discounts for bundling, good driving records, or safety features can lower your cost significantly.
Do I need insurance if I only drive on private property?
If you only drive on private property that you own, you may not need insurance in some states. However, if you ever drive on public roads, you must have insurance. Many people buy a policy just to be safe, since the line between private and public property can be unclear.
What is an SR-22 and why do I need it?
An SR-22 is a form your insurance company files with your state certifying that you have the required coverage. You need it if you have been convicted of uninsured driving, a DUI, or certain other violations. It is not a type of insurance — it is proof that you have insurance. Filing an SR-22 typically costs $15 to $25 and is required for a set period, usually three years.
