How to Figure Out What Car Insurance You Actually Need

Start with what your state requires, then add what protects your finances

Every state requires a minimum amount of liability insurance — the coverage that pays for damage or injuries you cause to someone else. That minimum varies by state: some require as little as $15,000 per person injured, others require $25,000 or more. You can find your state's minimum by searching "[your state] minimum car insurance requirements" or calling your state's Department of Insurance.

Liability is the foundation. After that, the coverage you need depends on three things: whether you own your car outright, whether you can afford to replace it if it's totaled, and how much financial risk you're willing to take on. A lender or lease company will require additional coverage. If you own the car free and clear, the choice is yours — but leaving yourself unprotected against a major accident can cost you far more than the insurance premium.

The rest of this guide walks you through each type of coverage, what it costs you to skip it, and how to decide what makes sense for your situation.

Key Takeaways

• Your state sets a legal minimum for liability coverage, which pays for injuries or damage you cause — find your state's requirement before shopping.
• If you financed or leased your car, the lender requires collision and comprehensive coverage; if you own it outright, those are optional but protect you from major losses.
• Uninsured motorist coverage protects you if someone without insurance hits you, and it costs very little compared to what an accident can cost.
• Deductibles (the amount you pay out of pocket) are the main lever for controlling your premium — raising your deductible lowers your monthly cost but raises what you pay if you have a claim.
• Once you know what coverage types you need, get quotes from at least two insurers, because the same coverage can vary in price by hundreds of dollars per year.

Liability coverage: the legal minimum and why you might want more

Liability coverage has two parts: bodily injury liability (pays for injuries to people in the other car) and property damage liability (pays for damage to their vehicle or property). Your state sets a minimum for each. A common minimum is 25/50/25, which means $25,000 per person injured, $50,000 total per accident, and $25,000 for property damage.

The problem with the minimum is that a serious accident can cost far more. A single person's medical bills, lost wages, and pain-and-suffering claim can easily exceed $50,000. If you're found liable for more than your coverage limit, you can be sued for the difference, and a judgment can follow you for years through wage garnishment or bank levies. Most insurance agents recommend at least 100/300/100 ($100,000 per person, $300,000 per accident, $100,000 property damage) or higher if you have significant assets to protect.

The cost difference between the state minimum and a higher limit is usually small — often $10 to $30 per month — because the insurer's biggest expense is the first claim, not the difference between a $50,000 and $100,000 payout. If you own a home or have savings, carrying higher liability limits is one of the cheapest ways to protect yourself.

Collision and comprehensive: required if you financed, optional if you own the car

Collision coverage pays to repair or replace your car if you hit something or something hits you — another car, a tree, a guardrail. Comprehensive coverage pays for damage from things other than collisions: theft, weather, vandalism, hitting an animal. If you have a car loan or lease, your lender requires both. If you own the car outright, they're optional.

The decision to carry collision and comprehensive on a paid-off car comes down to the car's value and your ability to replace it. If your car is worth $3,000 and you have $5,000 in savings, losing the car would hurt but wouldn't destroy you — you might skip collision. If your car is worth $15,000 and you have no emergency fund, an accident could leave you without transportation and without money to buy another one. In that case, collision makes sense even though you own the car.

Both collision and comprehensive come with a deductible — the amount you pay out of pocket before the insurance kicks in. A $500 deductible means you pay the first $500 of any claim; the insurer pays the rest. A $1,000 deductible costs less per month but means you pay more if you have a claim. Raising your deductible from $500 to $1,000 typically saves $100 to $200 per year, so the math depends on how often you think you'll file a claim and whether you have cash on hand to cover the deductible.

Uninsured and underinsured motorist coverage: protection against drivers without insurance

About one in eight drivers on the road has no insurance. If an uninsured driver hits you and is found at fault, their lack of insurance doesn't make your car repair itself — you're left paying out of pocket unless you have uninsured motorist coverage. This coverage pays for your injuries and vehicle damage when the other driver has no insurance or flees the scene.

Underinsured motorist coverage is similar but covers situations where the other driver has insurance but not enough to cover your damages. If you're hit by someone with only the state minimum liability ($25,000) and your medical bills are $60,000, underinsured motorist coverage pays the difference.

Both are inexpensive — usually $5 to $15 per month — and many states require them or allow you to decline them only in writing. If you have health insurance and a stable income, you have some protection against medical bills from an accident. But if you don't have health insurance or if you're self-employed, uninsured and underinsured motorist coverage is one of the most important protections you can buy.

Medical payments coverage and personal injury protection

Medical payments coverage (sometimes called "med pay") pays your medical bills and those of your passengers if anyone is injured in your car, regardless of who caused the accident. It covers hospital visits, surgery, dental work, and sometimes funeral expenses. It typically pays up to $1,000 to $5,000 per person and costs $10 to $25 per month.

Personal injury protection (PIP) is similar but broader — it also covers lost wages if you're injured and can't work, and childcare or household services you can't perform while recovering. PIP is required in some states (called "no-fault" states) and optional in others. If your state requires it, you'll see it on your quote. If it's optional and you have good health insurance and disability coverage through your job, you might skip it. If you're self-employed or have no disability coverage, PIP can be worth the cost.

Both med pay and PIP are secondary to your health insurance — they pay after your health insurance does — so they work together with your existing coverage rather than replacing it.

How deductibles affect your monthly cost and what you actually pay

A deductible is the amount you choose to pay out of pocket when you file a claim. Common deductible options are $250, $500, $750, and $1,000. Raising your deductible lowers your monthly premium because the insurer knows you're absorbing more of the risk.

The trade-off is real: a $250 deductible might cost you $120 per month for collision, while a $1,000 deductible might cost $90 per month — a $30 monthly savings, or $360 per year. But if you have a $5,000 accident claim, you pay $250 with the lower deductible or $1,000 with the higher one. That's a $750 difference on a single claim. If you go five years without a claim, you've saved $1,800 in premiums by choosing the higher deductible. If you have one accident in year two, you've lost money overall.

The right deductible depends on your emergency fund. If you have $2,000 in savings, a $1,000 deductible is manageable. If you have $500 in savings, a $500 deductible makes more sense because you can't afford to pay $1,000 out of pocket. Some people choose a higher deductible for collision (because they're less likely to file a claim) and a lower deductible for comprehensive (because comprehensive claims are often small, like glass repair).

Getting quotes and comparing what you're actually buying

Insurance companies price the same coverage differently based on their own risk models, claims history, and underwriting practices. One insurer might charge $1,200 per year for a 25-year-old driver with one speeding ticket; another might charge $1,500 for the exact same person. The only way to know is to get quotes.

Get quotes from at least two insurers — three is better. When you request a quote, you'll enter your driving history, the car you drive, the coverage types and limits you want, and your deductibles. The quote will show you the monthly or annual cost for that exact combination. Write down the coverage limits and deductibles for each quote so you're comparing apples to apples.

Don't choose based on price alone. An insurer's customer service, claims process, and financial stability matter too. Check your state's Department of Insurance website for complaint ratios — how many complaints each insurer receives per policy sold. A cheap quote from an insurer with a poor claims reputation can cost you time and frustration when you actually need to file a claim.

Once you've chosen an insurer and coverage, you'll receive a declarations page — a document that lists your coverage types, limits, deductibles, and premium. Keep this in your car or on your phone. If you're in an accident, you'll need it to file a claim.

Frequently Asked Questions

Do I need to carry the same coverage limits on all my cars?

No. You can set different deductibles and optional coverage (collision, comprehensive) on different cars. But liability limits explore across all your vehicles under one policy, so if you have multiple cars, you typically set one liability limit that covers all of them. Some people carry higher liability limits and skip collision on an older car while carrying collision on a newer one.

What happens if I get in an accident and I'm not sure who was at fault?

Report the accident to your insurer right away, even if you think the other driver was at fault. Your insurer will investigate, review police reports, and determine fault based on the evidence. If the other driver is found at fault, their insurer pays. If you're found at fault, your insurer pays (up to your coverage limits). If fault is split, both insurers may share the cost. Don't admit fault at the scene — just exchange information and let the insurers sort it out.

Can I lower my premium by raising my deductible to $2,500 or $5,000?

Some insurers offer very high deductibles, but most don't go above $1,000 or $1,500. The savings from a $2,500 deductible are usually small — maybe $10 to $20 per month — and the risk is high: if you have a claim, you're paying $2,500 out of pocket. A $1,000 deductible is usually the sweet spot for most people, balancing a reasonable monthly cost with a manageable out-of-pocket expense.

Do I need gap insurance if I financed my car?

Gap insurance covers the difference between what you owe on your car loan and what the car is worth if it's totaled. If you owe $20,000 on a car worth $18,000 and it's totaled, gap insurance pays the $2,000 difference. It's optional but can be worth it if you put down less than 20 percent on the car or if you're financing a car that depreciates quickly. Ask your lender or insurer about the cost — it's often $10 to $20 per month.

What should I do if I can't afford the insurance I think I need?

Start by getting quotes from multiple insurers — prices vary significantly. Then raise your deductibles to lower the premium. Skip optional coverage like gap insurance or PIP if your state allows it and you have other protection. Some insurers offer discounts for bundling home and auto insurance, paying in full instead of monthly, or completing a defensive driving course — ask about all of them. If you still can't afford coverage, talk to your state's Department of Insurance about low-income programs or assigned risk pools, which provide coverage to drivers who can't find it elsewhere.
