The coverage you need depends on your car's value, how you use it, and your state's minimum requirements

Every state requires you to carry liability insurance at minimum — this covers damage or injury you cause to someone else. Beyond that, the right coverage mix depends on whether you own your car outright, still owe money on it, and how much financial risk you can handle if something goes wrong. A lender will require certain coverage. You'll choose the rest based on your situation.

This guide explains what each type of coverage does, what your state likely requires, and how to think through what makes sense for your household.

Key Takeaways

  • Liability coverage is required by law in every state, but the minimum amounts are often too low to protect your assets if you cause a serious accident.
  • If you have a car loan or lease, your lender will require collision and comprehensive coverage until the loan is paid off.
  • Uninsured motorist coverage protects you if someone without insurance hits you, and it's required in many states.
  • Deductibles (the amount you pay out of pocket) are a trade-off: higher deductibles lower your premium but mean you pay more when you file a claim.
  • Your state's minimum requirements are a legal floor, not a financial recommendation — most financial advisors suggest carrying more.

Liability coverage: what your state requires and why it's often not enough

Liability coverage pays for damage or medical bills when you're at fault in an accident. It has two parts: bodily injury liability (medical bills and lost wages for the other person) and property damage liability (repair or replacement of their vehicle or property). Your state sets a minimum amount you must carry, but these minimums vary widely. Some states require as little as $15,000 per person for bodily injury; others require $25,000 or more.

The problem: if you cause a serious accident with multiple people injured, or if you hit an expensive car, the minimum coverage often won't cover the full cost. The injured party can then sue you personally for the difference. That's why financial advisors typically recommend carrying at least $100,000 per person and $300,000 per accident — sometimes written as 100/300. If you have significant assets (a house, savings, retirement accounts), carrying higher limits protects those assets from a lawsuit.

You can find your state's minimum requirements through your state's insurance commissioner's office or your insurance agent. The cost difference between the state minimum and a higher limit is usually modest — often $15 to $40 per year — but the protection is much larger.

Collision and comprehensive: required if you have a loan, optional if you own the car outright

Collision coverage pays to repair or replace your car if you hit another vehicle, a tree, a guardrail, or any other object. Comprehensive coverage pays for damage from events you don't cause: theft, weather, vandalism, hitting an animal. Both come with a deductible — typically $500 or $1,000 — meaning you pay that amount out of pocket before insurance kicks in.

If you have a car loan or lease, your lender requires both collision and comprehensive. They're protecting their investment in the car. Once you own the car outright, these are optional. Whether to keep them depends on the car's value and your ability to replace it. If your car is worth $3,000 and you have $10,000 in savings, paying for collision and comprehensive may not make financial sense — you could absorb the loss. If your car is worth $25,000 and you'd struggle to replace it, the coverage is worth the cost.

A useful rule of thumb: if the annual premium for collision and comprehensive is more than 10% of the car's value, dropping it may make sense. Your insurance agent can tell you what the annual cost would be.

Uninsured and underinsured motorist coverage: protection against drivers without insurance

Uninsured motorist coverage (UM) pays your medical bills and lost wages if someone without insurance hits you. Underinsured motorist coverage (UIM) covers you if the at-fault driver has insurance, but their limits are too low to pay for your injuries. Many states require you to carry UM; some allow you to decline it in writing, but most advisors recommend keeping it.

The cost is usually low — $10 to $30 per year depending on your state and the limits you choose. The protection can be significant: if an uninsured driver causes an accident that injures you, your own UM coverage pays your medical bills instead of forcing you to sue the other driver (who likely has no money anyway). In states where UM is optional, it's worth the small cost.

Your UM limits should match or exceed your liability bodily injury limits. If you carry 100/300 liability, carry at least 100/300 UM as well.

Medical payments coverage: a smaller, faster alternative to health insurance for accident injuries

Medical payments coverage (sometimes called MedPay) pays reasonable medical expenses for you and your passengers after an accident, regardless of who's at fault. It covers ambulance rides, emergency room visits, surgery, and follow-up care — up to the limit you choose, typically $1,000 to $5,000. It doesn't cover lost wages or pain and suffering, only actual medical costs.

This coverage is optional in most states and relatively inexpensive — often $5 to $15 per year for modest limits. It's useful if you have a high health insurance deductible or no health insurance at all, because it pays medical bills quickly without waiting for a liability claim to be resolved. If you have good health insurance, you may not need it; your health plan will cover accident injuries and may pursue the at-fault driver's insurance for reimbursement.

Deductibles: how they affect your premium and what you'll pay when you claim

A deductible is the amount you pay out of pocket when you file a claim. For collision and comprehensive, common deductibles are $250, $500, $1,000, or $2,500. A higher deductible lowers your premium; a $1,000 deductible might cost $200 per year less than a $250 deductible.

The trade-off is straightforward: if you choose a $1,000 deductible and you cause an accident that costs $5,000 to repair, you pay $1,000 and insurance pays $4,000. If you choose a $250 deductible, you pay $250 and insurance pays $4,750. Over time, if you rarely file claims, the lower premium from a higher deductible saves you money. If you file a claim, you pay more out of pocket.

A practical approach: set your deductible at the amount you could actually pay if you had an accident tomorrow. If you have $500 in emergency savings, a $500 deductible makes sense. If you have $2,000, you can comfortably handle a $1,000 deductible and save on premiums.

How to think about coverage if you're financing a car versus owning it outright

If you have a car loan or lease, your lender's requirements are non-negotiable: you must carry liability, collision, and comprehensive at the limits they specify. This is written into your loan agreement. You can't choose to drop collision to save money — the lender won't allow it.

If you own the car outright, you have full control. You must carry liability (it's the law), but collision, comprehensive, uninsured motorist, and medical payments are your choice. The question becomes: what's the worst-case scenario you can afford? If you hit someone and cause $200,000 in injuries, can you pay that? If your car is stolen, can you replace it? If you're hit by an uninsured driver, can you cover your own medical bills? Your answers to these questions should guide your coverage choices.

Frequently Asked Questions

What's the difference between state minimum coverage and what insurance companies recommend?

State minimums are the legal floor — the least you can carry without breaking the law. They're often too low to protect your personal assets if you cause a serious accident. Insurance companies and financial advisors typically recommend higher limits (like 100/300 liability) because the cost difference is small but the protection is much larger.

Do I need medical payments coverage if I have health insurance?

Not necessarily. Health insurance covers accident injuries, and your health plan may pursue the at-fault driver's insurance for reimbursement. Medical payments coverage is most useful if you have a high deductible or no health insurance. It pays quickly without waiting for a liability claim to resolve.

Can I drop collision and comprehensive to save money?

Only if you own the car outright. If you have a loan or lease, your lender requires both until the loan is paid off. If you own the car, you can drop them, but consider whether you could afford to replace or repair the car if something happens. If the annual premium is less than 10% of the car's value, keeping it usually makes financial sense.

What happens if I'm hit by an uninsured driver?

Your uninsured motorist coverage pays your medical bills and lost wages. If you don't have UM coverage, you'd have to sue the other driver personally — and if they have no insurance, they likely have no money to collect from. This is why UM coverage is worth the low cost, even in states where it's optional.

How do I know what deductible to choose?

Choose a deductible you could actually pay if you had an accident tomorrow. If you have $500 in emergency savings, a $500 deductible is realistic. If you have $2,000, a $1,000 deductible lets you save on premiums while staying within your means. Don't choose a deductible you can't afford just to lower your premium.
