How to Read a Car Insurance Quote (and Compare Two Fairly)

What is a car insurance quote, and why can the price change?

You have a quote on your screen, maybe three, and the prices are far apart. Before you pick the cheapest, check what each one covers. A low price often means thinner coverage, not a better deal. Quotes look like a wall of jargon, but a handful of lines decide almost everything. The short plan: ask every seller to price the same coverage, then compare. The steps are in “What to do next” near the bottom.

A quote is the insurer’s price estimate, built from the answers you gave. It is not a contract. After you apply, the company checks your driving record and your claims history. In states that allow it, it may also check a credit-based score. If a ticket, an old claim or a second driver turns up that you did not mention, the price can go up.

So treat the quote as a starting point. The page that counts is the declarations page, a short summary of the policy you actually bought. Three terms often get mixed up:

• Quote: an estimate of the price. It can change.
• Binder: a short-term agreement that covers you until the full policy is issued. Ask for it in writing, with an end date.
• Declarations page: the summary of your real policy. It lists your car, your drivers, each coverage, your limits, your deductibles, your price and the dates.

When the declarations page arrives, check every line against the quote.

How do I compare two car insurance quotes fairly?

Compare coverage first and price second. These lines must match before the prices mean anything:

• Injury and property limits (the three liability numbers, explained below).
• Uninsured driver coverage, kept or declined.
• Medical coverage choice, if your state has one.
• Collision and comprehensive deductibles.
• Any lawsuit option, in states that have one.
• The same drivers, cars, yearly mileage and address.
• The same policy length, six months or a year.

Be careful with the words “full coverage.” Insurance regulators, including the NAIC (the group of state insurance regulators) and Pennsylvania’s insurance department, say that no such policy exists. A policy is a bundle of separate coverages, each with its own limit and its own price. A quote that only says “full coverage” has told you nothing.

Two more points. List every driver in your home, including a student away at school, because a driver you leave off can mean extra premium or a denied claim. And get at least three quotes, as the NAIC advises.

What do the numbers like 100/300/100 mean?

Liability coverage pays for harm you cause to other people. It is written as three numbers:

• First (100): the most paid for one person’s injuries, here $100,000.
• Second (300): the most paid for everyone hurt in one crash, here $300,000.
• Third (100): the most paid for damaged property, here $100,000.

You owe anything above those caps. Some insurers sell one combined limit instead, a single pool for injury and property together.

Each state sets its own legal minimum, and the same numbers mean different things in different places. The details table lower down shows eight states. The state minimums guide covers the rest.

A minimum policy keeps you legal. It does not keep you safe. Say one hurt driver’s medical bills reach $80,000 (an example). With 25/50/25 limits, the policy pays at most $25,000 for that person, and the other $55,000 can be pursued from you. With 100/300/100, it pays the full $80,000. The NAIC advises buying as much liability coverage as you can reasonably afford. Try your own numbers in the liability limit checker.

What do the other lines on my quote mean?

Here is the plain version of each line you are likely to see:

• Uninsured and underinsured motorist: pays your injuries when the other driver has no insurance, too little, or drives off. The Insurance Research Council estimated that 15.4% of drivers were uninsured in 2023. See the uninsured motorist guide.
• Medical coverage (PIP or medical payments): pays medical bills for you and your passengers, whoever caused the crash. PIP can also cover lost wages.
• Collision: repairs your own car after a crash.
• Comprehensive: covers theft, fire, flood, hail, vandalism, animal strikes and falling objects.
• Rental and towing: pay a set amount a day or per tow, up to a cap.
• GAP: pays what you still owe on a car loan if the car is totaled and the insurer’s check falls short. See the GAP guide.

Most of these stop at the dollar limit shown. Collision and comprehensive work differently. They pay up to the car’s actual cash value, which is what it would cost to replace minus wear and age.

Know what a policy usually leaves out. Driving for a ride-hailing or delivery service, racing and trips into Mexico are common gaps, and so is gear that is not permanently installed. If you drive for pay, ask about an add-on before you accept a quote. If you have a car loan, keep collision and comprehensive. If they lapse, your lender can buy coverage that protects only the lender and add the cost to your loan.

How high should my deductible be?

A deductible is the part of a claim you pay yourself. Texas gives a simple example: on a $1,500 collision claim with a $500 deductible, the insurer pays you $1,000.

It applies when you claim on your own policy, even if the crash was not your fault. If you claim against the at-fault driver’s insurer instead, there is no deductible. Defaults differ too. Pennsylvania sets $500 for collision unless you ask for less, and New Jersey’s guide calls $750 standard.

A higher deductible lowers your price, but it raises the cost of every claim. Here is the math, with round example numbers. Moving from $500 to $1,000 puts $500 more on you per claim. If that saves $100 a year, you break even after five claim-free years. A claim sooner leaves you behind.

On an older car worth under $1,000, Pennsylvania says collision and comprehensive may not be worth buying.

One Michigan note: “collision” comes in three types. The broad form skips the deductible unless you are more than 50% at fault. Our source for this is state material from 2019 and 2020, so ask the insurer which types it sells today.

What happens if I skip a choice on the form?

In some states, a blank answer is still an answer. The state sets a default, and a cheaper quote may have taken the thinner side without telling you.

• Michigan: if you pick no level of medical coverage, unlimited is selected.
• Pennsylvania: if you do not choose limited tort, you are treated as keeping full tort. Limited tort lowers your price, but you give up the right to sue for pain and suffering unless an exception applies.
• New Jersey: if you leave the lawsuit option blank on a Standard policy, the state warns that the limited right to sue can be imposed.
• Texas: medical coverage (PIP) is included unless you decline it in writing. Uninsured motorist coverage must be offered, and you decline it in writing.

Ask each seller to show these choices on the quote. A New Jersey price with a limited right to sue is not comparable to one without.

Why do discounts, fees and credit change my price?

Discounts, fees and credit are where two similar quotes drift apart.

Discounts often attach to one coverage, so dropping that coverage drops its discount. Some are required by law. California’s Good Driver Discount must be at least 20% off for drivers who qualify, which depends on your recent record. Ask if you do. In Pennsylvania, when every named driver is 55 or older and has passed an approved course, the discount is at least 5% per car. Ask for each discount by name.

Fees and payment plans can add up. Ask for the total of all payments, not only the monthly figure. If you pay in installments through a separate finance company, refunds can go to that company first. Pennsylvania has no required grace period, so one late payment can end coverage.

Credit can raise your price in states that allow it. If a credit report played a part, federal law says the insurer must tell you, name the reporting agency, and explain that you can ask for a free report within 60 days. Our credit guide goes deeper, and how rates are calculated covers the other factors.

Example: two quotes, one real price gap

These numbers are made up to show the method. They are not real prices.

You get two quotes for the same car. Quote A is $95 a month. Quote B is $128 a month. At first glance A saves you $33 a month.

Then you line them up. A has 25/50/25 liability limits, no uninsured driver coverage and a $1,000 deductible. B has 100/300/100, uninsured driver coverage and a $500 deductible. They are not the same product.

You ask A to price B’s exact coverage. It comes back at $121 a month. The real gap is $7 a month, and for that you get four times the injury protection. In a bad crash, that difference could be tens of thousands of dollars.

What to do next

1. Copy your current coverage from your declarations page. If you are new to insurance, write down the limits, uninsured driver choice, medical choice and deductibles you want. Use that as your template.
2. Ask at least three companies or agents to quote that exact template, with the same drivers, cars, mileage and address.
3. Check each quote against the list in the comparison section above. Mark anything that differs.
4. Ask each seller for the total of all payments for each plan, and for every fee by name.
5. Before you pay, confirm the seller is licensed. Pay the insurer directly, then call the insurer yourself to confirm a policy exists in your name.
6. Keep your old policy until the new one is active and the declarations page is in your hands. Check each line against the quote.
7. If the final price jumps, ask which report caused it, and ask for the reasons in writing. Not sure your state works the way this guide says? Check with your state insurance department. The NAIC lists them at content.naic.org/state-insurance-departments.

How can I spot a fake or risky quote?

Texas’s insurance department warns about people with no license who collect your money and never buy a policy. Watch for these signs:

• A price far below everyone else, plus pressure. An “act today” deadline is usually a bad sign.
• A request to pay a person or a third-party payment app. Pay the insurer, not the agent. The insurer’s own app is fine.
• No confirmation. Phone the insurer yourself after you buy.
• Choices you never made. A lawsuit or uninsured driver option that shows up without your say-so.
• “Full coverage” with no limits listed. You cannot compare it.

Details: liability minimums and choices by state

The three liability numbers are in thousands of dollars. Rules change, so confirm with your state insurance department.

Bottom line

If two quotes differ by a lot, assume the coverage differs until you prove it does not. If a quote only lists a price, ask for the limits, deductibles and choices in writing. If you are tempted by the legal minimum, ask what you would owe in a serious crash first. And if a seller rushes you or wants payment to a person or a third-party payment app, stop and call the insurer directly.
