Finding the Cheapest Car Insurance: What Minimum Coverage Costs

The lowest car insurance is liability-only coverage in your state, which covers damage you cause to someone else's car or property — not damage to your own vehicle.

Every state except New Hampshire requires you to carry at least liability insurance before you can legally drive. The minimum amount varies by state: some require $25,000 per person for bodily injury, others require $50,000 or $100,000. Property damage minimums range from $10,000 to $25,000 in most states. A liability-only policy covers only the other driver's repairs, medical bills, and lost wages if you cause an accident — your own car is not covered.

The actual dollar cost of the lowest policy depends on where you live, your age, driving record, and the car you drive. A 40-year-old with a clean record in a rural area might pay $40 to $60 per month for state-minimum liability. A 25-year-old in an urban area with one accident on their record could pay $150 to $250 per month for the same coverage. Insurance companies do not publish a single "lowest price" because the risk calculation is different for every driver.

Key Takeaways

• Liability-only coverage is the cheapest legal option in all states except New Hampshire, and it covers only damage you cause to someone else, not your own vehicle.
• State minimum liability limits vary: some states require $25,000 per person for bodily injury and $10,000 for property damage, while others require $50,000 or $100,000.
• Your actual monthly cost depends on your age, driving history, location, and the vehicle you insure — there is no single lowest price across all drivers.
• Collision and comprehensive coverage add cost but protect your own car; skipping them saves money but leaves you uninsured if your car is damaged or stolen.

How State Minimums Work

Your state's Department of Insurance or Motor Vehicles publishes the minimum liability limits you must carry. These are split into two parts: bodily injury liability (which covers medical expenses and lost wages for people you injure) and property damage liability (which covers repairs to the other driver's vehicle or property). You will see these written as three numbers, like 25/50/25, meaning $25,000 per person for bodily injury, $50,000 total per accident for bodily injury, and $25,000 for property damage.

The lowest-cost policy meets your state's minimum and includes nothing else. If you cause a crash and the other driver's medical bills exceed your bodily injury limit, they can sue you personally for the difference. If your car is damaged in an accident you caused, hit by an uninsured driver, stolen, or damaged by weather, you have no coverage and must pay for repairs yourself. This is why liability-only is the cheapest option — the insurance company's risk is limited to what other people claim against you, not your own vehicle.

Why Actual Prices Vary So Much

Two drivers buying the same state-minimum liability policy can pay vastly different premiums because insurance companies use different rating factors. Age is one of the largest: drivers under 25 and over 75 pay more because they have higher accident rates. A single accident or traffic violation can double or triple your rate for three to five years. Where you live matters — urban areas with more traffic and theft have higher rates than rural areas. The type of car you drive affects price: a sports car costs more to insure than a sedan, and a car with safety features may cost less.

Some companies also factor in credit score, marital status, occupation, and how far you drive to work. One company might charge $45 per month and another $120 per month for the same driver and coverage because they weight these factors differently. This is why comparing quotes from at least three insurers is necessary to find the lowest price for your specific situation — there is no universal "cheapest" company.

Liability-Only Versus Coverage That Protects Your Car

Collision coverage pays to repair or replace your car if you hit another vehicle, object, or rollover. Comprehensive coverage pays if your car is stolen, damaged by weather, vandalized, or hit by an uninsured driver. Both come with a deductible — usually $500 or $1,000 — that you pay out of pocket before the insurance pays. Adding collision and comprehensive to a liability-only policy typically increases your monthly cost by $30 to $80, depending on your car's age and value.

If you own your car outright, you can legally choose liability-only and skip collision and comprehensive. If you have a loan or lease, your lender requires you to carry collision and comprehensive, so you cannot choose the absolute lowest option. If your car is worth less than $3,000, the cost of collision coverage may exceed what you would receive if the car were totaled, making liability-only the practical choice even if you could afford the extra coverage.

How to Find the Lowest Price for Your Situation

Start by determining your state's minimum liability limits — your state's insurance department website lists them. Then get quotes from at least three major insurers: Geico, State Farm, Progressive, and Allstate are the largest, but regional companies like USAA (if you are military or a veteran) or local mutual insurers sometimes offer lower rates. Most companies offer online quotes that take 5 to 10 minutes and do not require a phone call.

When you get quotes, make sure they are all for the same coverage — state minimum liability only — so you are comparing the same thing. Ask about discounts: bundling home and auto insurance, paying in full instead of monthly, maintaining a clean driving record, or completing a defensive driving course can each lower your rate by 5 to 15 percent. Some insurers offer usage-based programs where they track your driving habits through an app and lower your rate if you drive safely.

What Happens If You Cannot Afford Even the Lowest Option

If you cannot afford liability-only insurance, you cannot legally drive in most states. Some states offer low-income programs or assigned risk pools where drivers who have been denied coverage by standard insurers can obtain a policy, though the rates are usually higher than standard market rates. Contact your state's insurance department to ask about these programs — they are sometimes called "residual market" or "assigned risk" plans.

Another option is to stop driving temporarily and use public transportation, rideshare, or carpooling until your financial situation improves. If you have a suspended license due to unpaid tickets or a previous accident, you may need to resolve those issues before any insurer will cover you, regardless of price.

Frequently Asked Questions

Is liability-only insurance legal everywhere?

Liability-only is legal in all states except New Hampshire, which does not require insurance but requires you to prove you can pay for damages if you cause an accident. In the other 49 states, liability-only meets the legal minimum, though your lender may require more coverage if you have a car loan.

Can I get car insurance for less than $30 a month?

It depends on your age, location, and driving record. A 40-year-old with a clean record in a rural area might find liability-only for $25 to $40 per month. A younger driver or someone in an urban area will likely pay more. Getting quotes from multiple insurers is the only way to know what is available in your area.

What if I cause an accident and my liability limit is not enough?

The other driver can sue you personally for the difference. If you have assets like a house or savings, they can pursue a judgment against those assets. This is why some drivers carry limits higher than their state's minimum — it costs only $5 to $15 more per month but protects you from a lawsuit.

Does my credit score affect my car insurance rate?

Many insurers use credit score as a rating factor, though some states restrict how much it can affect your rate. A lower credit score can increase your premium by 10 to 30 percent with some companies. If you have poor credit, comparing quotes is especially important because different insurers weight credit differently.

What if I drive very little — can I get a cheaper rate?

Yes. Some insurers offer low-mileage discounts if you drive fewer than 5,000 or 7,500 miles per year. Usage-based programs like Geico's DriveEasy or Progressive's Snapshot track your actual driving and can lower your rate if you drive safely and infrequently. Ask insurers about these options when you get quotes.
