Breaking Down the Most Confusing Word in Car Insurance

“Full coverage” is a term that gets used so often in the world of car ownership that it almost loses its meaning. It sounds so comforting, doesn’t it? Like a warm blanket of complete safety for your car, it will keep it safe. You say “full coverage” with a certain amount of confidence when you say it. But if I asked you what it really is, could you tell me?

You’re not the only one who thought about it. You are actually in the vast majority.

Welcome to the ultimate guide that will help you understand this important part of auto protection. I’m not an agent trying to sell you something; I’m a seasoned writer and consumer advocate who has spent years studying these policies. I’m here to help you navigate the maze of auto insurance. We’re going to take a look behind the scenes at “full coverage,” talk about your specific insurance needs, and give you the information you need to make the best choice for your car, your wallet, and your peace of mind.

I’ve been dealing with insurance for a long time, and the one thing that always confuses me the most is this very topic. Drivers either pay too much for coverage they don’t need on an older car or, even worse, they don’t get the coverage they need on a new car because they think their basic policy is enough. This post will clear up any confusion. We will go very deep to make sure that by the end, you not only know what full coverage is, but you also have a way to decide if it’s right for you. Get ready to go from being a passive policyholder to being in charge of your own financial security.

Breaking Down “Full Coverage”: What Are You Really Buying?

“Full coverage” is not a specific type of insurance policy. This is the first and most important thing you need to know. You can’t just call an agent and say, “Give me the full coverage policy,” and have them take a standard product off the shelf.

It’s a piece of industry slang that means a combination of different coverages put together. Instead of a set menu, think of it as a combo meal that you put together yourself. The exact combination may change a little, but it usually refers to a policy that has three main parts:

  1. Liability Insurance (This is the part that most of the time the law requires).
  2. Collision Insurance (This protects your car).
  3. Comprehensive Insurance (This also covers your car, but from different risks).

Most people think of “full coverage” as having these three things. You have liability protection if you damage someone else’s property, and you have collision and comprehensive protection for your own car against a wide range of possible disasters.

Let’s look at each of these pillars one by one.

Pillar 1: Liability Coverage—The Foundation That Can’t Be Changed

Liability insurance is something that every responsible driver should have. In fact, 49 out of 50 states require it by law (New Hampshire is the only one that doesn’t, but they do have requirements for financial responsibility). This is the most important part of your auto protection plan.

Liability insurance won’t pay to fix your car or cover your injuries. Its only job is to pay for the damage you do to other people if you’re at fault in an accident. There are two parts to it:

  • Bodily Injury Liability (BI): This pays for the medical bills, lost wages, and pain and suffering of people you hurt in an accident. It is usually shown as two numbers, such as $25,000 and $50,000. The first number is the most money that each person can get, and the second number is the most money that each accident can get.
  • Property Damage Liability (PD): This pays to fix or replace the property you damage, which is usually the other person’s car. It could also cover a mailbox, a fence, or even a storefront that you crashed into.

Tip for the Real World: The minimum liability limits in some states are often shockingly low. A small accident with a newer car and a trip to the emergency room can easily cost more than $25,000. You are putting your assets (like your home and savings) at risk if you do this. If you hurt someone more than your liability limits allow, they can sue you personally for the difference. The Insurance Information Institute says that you should get coverage that is much higher than what your state requires. This is one of the most important things to think about when figuring out what your real “insurance needs” are.

Pillar 2: Collision Insurance—Keeping Your Car Safe from Collisions

This is the first part of the “keep my car safe” equation. Collision coverage pays to fix or replace your own car after it gets damaged in a crash with another object, as the name makes clear.

That “thing” is very important. Most of the time, it’s another car, but it can also be

  • Hitting something that isn’t moving, like a tree, a guardrail, or a pole.
  • Backing into your garage door by mistake (it happens!).
  • Damage from an accident where the car rolled over.
  • Getting hit by a driver who doesn’t have insurance and then running away (this can also be covered by Uninsured Motorist coverage, which we’ll talk about later).

Collision coverage has a deductible, which is the amount you have to pay before the insurance company will pay for anything. Most deductibles are between $250 and $2,000. Your premium will go down if you choose a higher deductible, but you need to be sure you can easily pay that amount out of pocket at any time.

Pillar 3: Comprehensive Insurance—Covering (Almost) Everything Else

Collision coverage is for damage caused by crashes, while comprehensive coverage is for strange, annoying, and often unpredictable events that don’t involve a crash. Some people call it “other than collision” coverage, which is a very good name for it.

Comprehensive insurance covers damage to your car caused by things like

  • Theft and Vandalism: Someone steals your car or purposely scratches it, breaks a window, or slashes your tires.
  • Weather Events: Hailstorms that make your car look like a golf ball, floodwaters from a hurricane, or a tree branch falling on it during a windstorm.
  • Fire and Explosions: A fire in an engine or another fire that isn’t an accident.
  • Animal Collisions: A common example is hitting a deer on a country road. This is a surprisingly common and costly type of claim.
  • Falling Objects: Things that fall from an overpass, a truck in front of you that isn’t properly secured, etc.
  • Civil Commotion: Damage caused by a riot or other public disturbance.

Comprehensive coverage, like collision, also has a deductible. A lot of people choose to have the same deductible for both, but you can choose different ones for each. If you live in an area where a lot of cars get stolen but you are a very careful driver, you might choose a lower comprehensive deductible and a higher collision deductible.

The million-dollar question is, do you really need full coverage?

Now we get to the point. Liability + Collision + Comprehensive = “full coverage.” But do you really need that whole package? The answer is a loud “it depends.”

This isn’t a choice that works for everyone. This is a very personal financial decision that depends on three important things: how much your car is worth, how much money you have, and how much risk you are willing to take. Let’s build a structure to help you make a choice.

The Financial Litmus Test: The Actual Cash Value (ACV) of Your Car

How much your car is worth is the most important thing to think about when making this choice. Insurance companies don’t care how much you paid for it. They want to know what its Actual Cash Value (ACV) was when the claim was made. ACV is the cost of replacing the car minus how much it has lost value. Every day, the value of a car goes down.

Here’s a common rule of thumb that financial advisors, like those at Forbes Advisor, use to help them make this choice:

The 10% Rule says that if your full coverage costs more than 10% of your car’s actual cash value (ACV), you might want to think about dropping it.

Let’s get real:

  • Scenario A: The New SUV
  • You have a 2024 Toyota Highlander that is worth $40,000.
  • Your premium for collision is $600 a year.
  • The part that covers everything costs $200 a year.
  • The total cost of your “full coverage” is $800 per year.
  • Calculation: Two percent of $40,000 is only $800.
  • Conclusion: You should definitely keep full coverage. It would be foolish with money not to protect such a valuable asset.
  • **Scenario B: The Old Car for Commuting
  • You have a 2010 Honda Civic with 150,000 miles on it. You look up its value on Kelley Blue Book and find that its ACV is about $4,000.
  • Your total collision and comprehensive premiums are $500 a year.
  • Calculation: $500 is 12.5% of $4,000.
  • Conclusion: You’ve gone over the 10% mark. You are now paying a large part of the car’s total value every year just to protect it from physical damage. In this case, it might be better for your finances to drop full coverage and “self-insure” by putting that $500 a year into a separate car fund.

Helpful Hint: Don’t guess when you want to know your car’s ACV. Use reliable websites like Kelley Blue Book (kbb.com) or Edmunds (edmunds.com). Find out how much a car like yours with your mileage would sell for in a private sale. This number is your guiding star.

The Forced Hand: When Loans and Leases Decide for You

In some cases, the choice is completely out of your hands. If you have a car loan or are leasing your car, your lender or leasing company will almost always require you to have full coverage.

Why? They own the car legally until you pay off the loan or give back the lease. It’s their property, and they need to keep it safe. If you totaled the car without collision or comprehensive coverage, the lender would lose tens of thousands of dollars. They don’t want to take that chance.

If you have a lienholder on your title, full coverage is probably required. If you don’t keep it up, you are breaking your loan agreement and could face serious consequences, such as the lender buying a very expensive policy for you (called “force-placed insurance”) and adding the cost to your loan.

Your Personal Risk Profile: Where You Live, What You Do, and How Much Money You Have

Your life circumstances are just as important as how much your car is worth. Your environment and how stable your finances are will affect your personal insurance needs.

  • Where You Live: Do you live in a busy city with lots of traffic and limited street parking? This makes it more likely that your car will get dinged, dented, or hit-and-run. Do you live in an area that gets a lot of bad weather, like hailstorms (Texas, Oklahoma), hurricanes (Florida, Louisiana), or a lot of snow? Do people in your area often steal cars? If you answer “yes” to any of these questions, it makes a stronger case for keeping comprehensive coverage, even on a car that’s a little older.
  • Your Driving Habits: How often do you drive? A car that drives 50 miles a day to work is much more likely to get into an accident than a car that only drives on the weekends and gets 3,000 miles a year.
  • Your Financial Safety Net: This is a very honest look at yourself. If you totaled your car tomorrow and only got a check for its ACV (or nothing if you dropped full coverage), could you afford to buy a new one? Do you have a strong emergency fund? Could you buy another dependable car with cash without messing up your other money goals? If the answer is no, then paying for full coverage might be the more responsible choice because it protects your money when you drive.

A Closer Look at Total Auto Protection: More Than Just “Full” Coverage

A good auto protection plan usually includes more than just liability, collision, and comprehensive. If you only use these three, you could leave dangerous holes in your financial armor. You need to know about and think about these other important types of coverage to really be safe. Think of these as ways to make your armor more personal.

Uninsured/Underinsured Motorist (UM/UIM) Coverage: Your Shield Against the Irresponsible

I think this is one of the most important and least talked about types of insurance you can get. What if a driver hits you and doesn’t have any insurance at all, or only the bare minimum state-required liability that doesn’t even come close to covering your medical bills?

That’s when UM/UIM comes in. It pretty much takes the place of the other driver’s insurance that isn’t there or isn’t enough.

  • Uninsured Motorist (UM): If you’re hit by a driver who doesn’t have insurance, this insurance will pay for your medical bills and, in some states, damage to your property. It also protects you in a hit-and-run.
  • Underinsured Motorist (UIM): This kicks in when the driver who caused the accident has insurance, but their coverage isn’t enough to pay for your bills. If you have $100,000 in medical bills and the driver who hit you only has a $25,000 policy, your UIM coverage could pay the other $75,000.

The Insurance Research Council says that almost 1 in 8 drivers on the road doesn’t have insurance. This means that not getting this coverage is a huge risk.

Personal Injury Protection (PIP) and Medical Payments (MedPay)

These coverages help pay for your and your passengers’ medical bills after an accident, no matter who was at fault. This is a key distinction. You don’t have to wait for a long time for a fault investigation to pay your bills.

  • Medical Payments (MedPay): This is a simple type of insurance that pays for medical and funeral costs up to a certain amount, like $5,000 or $10,000. You can use it to pay your health insurance deductible.
  • Personal Injury Protection (PIP): This is more complete than MedPay. In “no-fault” states, it’s required. PIP not only pays for your medical bills, but it can also pay you back for lost wages and the cost of hiring someone to do important tasks (like cleaning or taking care of children) that you can’t do because of your injuries.

You might not need as much of this coverage if you have good health insurance with a low deductible. If you have a high-deductible health plan or no health insurance, though, PIP or MedPay is a must. Our guide on “Understanding Your Auto Insurance Declaration Page” can help you learn more about this.

The Important Extras: Gap, Rental, and Roadside

People often think of these as “add-ons,” but they can save your life in some situations.

  • Gap Insurance: The value of a new car drops as soon as you drive it off the lot. If you crash that car in the first few years, the insurance company might pay you less than what you still owe on the loan. This difference is called the “gap.” Gap insurance pays off this difference so you don’t have to keep making payments on a car that doesn’t exist anymore. You need this if you put down a small amount of money on a new car and are financing it. This is the subject of a whole article called “Gap Insurance: Is It Worth It for Your New Car?.”
  • Rental Reimbursement: What will you do if your car is in the shop for repairs after a covered claim? Rental reimbursement covers the cost of a rental car for a set amount of time, up to a certain daily limit (like $40 per day). Adding it is usually very cheap, and it can save you hundreds of dollars and a lot of trouble.
  • Roadside Assistance: This includes things like towing, changing flat tires, jump-starting batteries, and getting you back into your car if you lock yourself out. Adding this to your car insurance policy is often the cheapest way to get it, even though a lot of people already have it through other means, like AAA or a credit card.

A Step-by-Step Guide to Personalizing Your Insurance Needs

Okay, that’s enough theory for now. Let’s put all of this into action. Get a notebook or open a spreadsheet. It’s time to make the policy you want.

Step 1: Get an Unbiased Valuation of Your Vehicle

First, visit Kelley Blue Book (kbb.com) or a site like it. Be honest about the year, make, model, mileage, and condition of your car. Get the value of “Private Party.” This is the number for your ACV. Put it down.

Step 2: Do a brutally honest self-assessment of your finances

Check your money.

  • Emergency Fund: How much money do you have saved in an emergency fund that you can get to easily? Is it enough to pay for a big, unplanned cost?
  • Car Replacement Fund: If your car, which is worth $6,000, got totaled tomorrow, would you be able to write a check for $6,000 to buy a new one without it messing up your life?
  • Deductible Affordability: Check the collision/comprehensive deductibles you chose (like $500 or $1,000). Could you pay that much tomorrow without any problems? If not, you need to either choose a lower deductible (which will raise your premium) or save a lot of money until you can.

Use the Deductible-Premium Seesaw to Have Fun

The amount you have to pay out of pocket and the amount you pay in premiums are related in the opposite way.

  • A higher deductible means a lower premium.
  • A lower deductible means a higher premium.

You can get an online quote from a big company like Progressive or Geico. Most quote tools let you change your deductible levels in real time to see how they affect the price. Find out how much money you can save by raising your deductible from $500 to $1,000. If you can save a lot of money each year (like $200), it might be worth getting the higher deductible if you have that $1,000 saved up. You are basically putting money on yourself to drive safely.

Step 4: Learn how to shop and negotiate like a pro

Don’t ever take the first quote you get. And don’t stay with the same insurance company for years without shopping around for a new policy. Insurance companies don’t often reward loyalty.

  • Compare Apples to Apples: Get quotes from at least three to five different insurance companies. To make a fair comparison, make sure that each one has the same coverage limits and deductibles.
  • Request Discounts: After you get a quote, call an agent and ask them to look it over for discounts. There are a lot of them that you might be able to get. For a full list, see our guide “15 Auto Insurance Discounts You’re Probably Missing Out On.” Some common ones are
  • Discounts for good students
  • Finishing a defensive driving course
  • Multiple policies (combining home/renters and auto)
  • Discount for paying in full
  • Automatic payments and billing without paper
  • Discount for low mileage
  • Certain professions (like teachers, engineers, etc.) get discounts.
  • Check Your Credit: In a lot of states, your credit-based insurance score is a big part of how much you pay. You can lower your premiums right away by raising your credit score. Check out our in-depth article, “How Your Credit Score Affects Your Car Insurance Rates,” for more information.

The Final Decision: Is Full Coverage Necessary or Just a Nice Thing to Have?

As we’ve seen, the answer isn’t as simple as yes or no. For some people, “full coverage” is a must-have, while for others, it’s a nice-to-have or even a bad financial decision.

**Full coverage is probably a MUST if:

  • You are leasing or financing your car.
  • Your car is newer or worth a lot of money (more than $5,000 to $7,000, depending on your finances).
  • You couldn’t afford to fix or replace your car on your own without a lot of financial trouble.
  • The peace of mind that comes from knowing your asset is safe is worth the extra money to you.

Full coverage might be a LUXURY (or not needed) if:

  • You own your car completely.
  • The car’s ACV is low; a common benchmark is less than $4,000.
  • The cost of collision and comprehensive coverage each year is more than 10% of the car’s ACV.
  • You have a good emergency fund and could easily pay for a new car.
  • You are willing to take the chance of losing everything in exchange for a lower monthly payment.
