How Much Car Insurance Coverage You Actually Need

What "full coverage" means and why the term is misleading

Full coverage is not an official insurance term — it is what people call a combination of liability, collision, and comprehensive coverage together. Your state requires liability. Collision and comprehensive are optional, but your lender requires them if you have a loan or lease. The amount you need depends on your car's value, your assets, and your state's minimum requirements, not on what insurance companies call "full".

Liability coverage pays for damage you cause to someone else's car, property, or body. Every state sets a minimum, but that minimum is usually too low to protect you if you cause a serious accident. Collision covers damage to your own car from a crash. Comprehensive covers theft, weather, vandalism, and hitting an animal. None of these three covers your medical bills — that is what medical payments coverage or uninsured motorist coverage does.

Reddit threads about car insurance often pit "minimum coverage" against "full coverage" as if those are the only two choices. They are not. You can buy liability limits higher than your state's minimum, add uninsured motorist coverage, skip collision on an old car, or adjust your deductible. The right mix depends on what you are protecting.

Key Takeaways

• Your state sets a minimum liability limit, but that minimum often leaves you personally responsible for costs above it if you cause a serious accident.
• Collision and comprehensive are optional unless you have a loan or lease, and skipping them on a paid-off car worth less than $5,000 usually makes financial sense.
• The coverage you need depends on your car's value, how much money you have in savings, and whether you could afford to replace the car out of pocket.
• Uninsured motorist coverage protects you if someone without insurance hits you, and it is separate from collision and comprehensive.
• Raising your deductible from $500 to $1,000 lowers your premium but means you pay more out of pocket when you file a claim.

State minimum liability limits and why they are often not enough

Every state requires you to carry liability insurance, but the minimum amount varies. Some states require as little as $15,000 per person and $30,000 per accident for bodily injury, plus $5,000 for property damage. Other states require $25,000 per person and $50,000 per accident. A few require higher amounts. You can find your state's requirement on your state insurance commissioner's website or by calling your insurer.

The problem is that a serious accident can cost far more than your state's minimum. If you hit someone and cause $100,000 in medical bills, and your liability limit is $25,000, you are personally responsible for the remaining $75,000. The injured person can sue you, garnish your wages, or place a lien on your home. Most insurance experts recommend carrying at least $100,000 per person and $300,000 per accident in bodily injury liability, plus $100,000 in property damage. The premium difference between your state's minimum and these higher limits is usually $10 to $30 per month.

Reddit users often ask whether they should raise their liability limits. The answer is almost always yes, unless you have no assets to protect. If you own a home, have savings, or earn a steady income, a lawsuit judgment can follow you for years. Higher liability limits cost very little and protect you from that risk.

Collision and comprehensive: when to buy them and when to skip

Collision and comprehensive are bundled together in most conversations, but they cover different things. Collision pays to repair or replace your car if you hit another car, a tree, a guardrail, or anything else. Comprehensive pays if your car is stolen, damaged by weather, vandalized, or hit by an animal. Both come with a deductible — usually $500 or $1,000 — that you pay out of pocket before insurance pays the rest.

If you have a loan or lease, your lender requires both. If you own your car outright, you can choose. The decision comes down to whether you could afford to replace the car if something happened to it. If your car is worth $8,000 and you have $10,000 in savings, collision and comprehensive make sense because you could not easily replace the car. If your car is worth $2,000 and you have $20,000 in savings, skipping them saves you money because you can absorb the loss. The break-even point is roughly when your annual collision and comprehensive premium equals 10 percent of your car's value.

Many Reddit users report dropping collision and comprehensive once their car is paid off and worth less than $5,000. That is a reasonable choice if they have an emergency fund. Others keep comprehensive but drop collision to save money while still protecting against theft and weather damage. Your insurer can quote you the cost of each separately so you can do the math yourself.

Uninsured and underinsured motorist coverage protects you, not them

Uninsured motorist coverage pays your medical bills and car damage if someone without insurance hits you. Underinsured motorist coverage pays the difference if the at-fault driver's liability limit is too low to cover your costs. These are separate from collision and comprehensive, and many people forget about them entirely.

About 13 percent of drivers nationwide carry no insurance, and that number is higher in some states. If an uninsured driver hits you and causes $30,000 in damage, your collision coverage pays for the car, but your medical bills are your problem unless you have uninsured motorist coverage. Some states require it; others make it optional. Even where it is optional, it usually costs $10 to $20 per month and is worth buying. It protects you and your passengers, not the other driver.

Underinsured motorist coverage is less common but useful if you live in a state with low minimum liability limits. If a driver with only the state minimum hits you and causes $80,000 in damage, underinsured motorist coverage bridges the gap. Ask your insurer whether your state requires either of these and what the cost is.

Medical payments coverage versus uninsured motorist coverage

Medical payments coverage (sometimes called MedPay) pays your medical bills and your passengers' medical bills after any accident, regardless of who is at fault. It does not matter if you caused the crash or someone else did — it pays. The limit is usually $1,000 to $5,000 per person, and it costs $10 to $25 per month depending on the limit you choose.

Uninsured motorist coverage also pays medical bills, but only if the other driver is uninsured or underinsured. If you are hit by an insured driver, uninsured motorist coverage does not pay your medical bills — the at-fault driver's liability coverage does. Medical payments coverage fills that gap by paying first, regardless of fault, so you do not have to wait for the other insurance company to process a claim.

If you have good health insurance with a low deductible, medical payments coverage may be redundant. If you have a high deductible or no health insurance, it is worth buying. Reddit users with young families often add it for peace of mind because it covers passengers too.

How your deductible affects your premium and out-of-pocket costs

Your deductible is the amount you pay out of pocket before insurance pays the rest. Common deductibles are $250, $500, $1,000, and $2,500. Raising your deductible from $500 to $1,000 typically lowers your premium by 10 to 15 percent. Raising it to $2,500 can lower it by 25 percent or more. The trade-off is that you pay more when you file a claim.

The math is straightforward: if raising your deductible saves you $200 per year but you file a claim once every five years, you come out ahead. If you file a claim every year, a higher deductible costs you money overall. Most people file a collision or comprehensive claim once every five to ten years, so a higher deductible usually saves money in the long run. However, you need to be able to afford the deductible out of pocket when a claim happens.

Reddit users often ask whether they should raise their deductible to save on premiums. The answer depends on your emergency fund. If you have $2,000 in savings and your deductible is $1,000, you can afford it. If you have $500 in savings, a $1,000 deductible is risky because you would have to put the deductible on a credit card if you had a claim. Keep your deductible at a level you can actually pay.

How your car's age and value change what coverage makes sense

A new car worth $35,000 needs different coverage than a ten-year-old car worth $5,000. For a new car, collision and comprehensive are essential because the cost of repair or replacement is high. For an old car, the math changes. If your car is worth $3,000 and collision costs $50 per month, you are paying $600 per year to protect a $3,000 asset. If you have savings, self-insuring (skipping collision and keeping the money) often makes sense.

The age of your car also affects repair costs. Newer cars are more expensive to repair because parts are pricier and labor rates are higher. Older cars are cheaper to repair but more likely to need repairs. Some people keep collision on an older car but raise the deductible to $1,000 to lower the premium. Others drop it entirely and set aside the premium savings into a repair fund.

Your car's safety rating matters too. Newer cars with advanced safety features are less likely to be in a serious accident, which can justify lower liability limits. Older cars without these features may warrant higher liability limits because you are at greater risk of causing a serious accident.

Frequently Asked Questions

What is the difference between full coverage and comprehensive coverage?

Comprehensive is one piece of what people call "full coverage." Full coverage usually means liability plus collision plus comprehensive. Comprehensive alone covers theft, weather, and vandalism but not crashes. Collision covers crashes. You need both to have what most people mean by "full coverage."

Can I get a discount if I bundle home and car insurance?

Yes. Most insurers offer a discount of 10 to 25 percent if you bundle home and auto policies. Some also offer discounts for bundling auto with renters insurance. Ask your insurer what discounts are available and whether bundling saves you money compared to shopping around for separate policies.

Do I need collision if I have comprehensive?

Comprehensive does not cover crashes, so yes, you need collision if you want protection from hitting something. Comprehensive covers theft, weather, and vandalism. If you have a loan or lease, your lender requires both. If you own the car outright, you can choose to buy only comprehensive and skip collision, though that leaves you unprotected in a crash.

What happens if I let my insurance lapse?

Driving without insurance is illegal in every state. If you are caught, you face fines, license suspension, and a mark on your driving record that raises your rates for years. If you cause an accident while uninsured, you are personally responsible for all damages. If you cannot afford your premium, contact your insurer about payment plans or ask about discounts you may have missed.

Should I buy insurance from the same company that insures my home?

Not necessarily. Bundling saves money, but only if that company's auto rates are competitive. Get quotes from at least three insurers before deciding. Sometimes a standalone auto insurer is cheaper than bundling with your home insurer, even after the bundle discount. Compare the total cost, not just the discount.
