In this guide

Two car insurance quotes can show nearly the same monthly price and cover very different things. The difference is usually in the limits, the deductible and the exclusions.

Before you compare premiums, compare what happens after a claim.

What the main coverages do

  • Liability pays for damage or injuries you cause to someone else.
  • Collision pays for damage to your car, minus the deductible.
  • Comprehensive covers theft, weather, fire and other non-collision damage.
  • Medical payments helps with medical bills for you and your passengers.

The coverage gap to check

Uninsured and underinsured motorist coverage is the gap drivers most often miss. It pays when the other driver cannot. Ask for the limits in writing, not just the label on the quote.

Ask this before you buy

What is my out-of-pocket cost after a total loss, and what is excluded from this policy?

How to compare quotes

Use the same coverage limits, deductibles and drivers for every quote. Then compare the annual premium, not the monthly payment. A low monthly price can hide a large down payment or a short policy term.

The right policy is the one that covers the loss you cannot afford to pay for yourself.

Common questions

Is the cheapest car insurance always the worst?

No. Price matters. But compare the limits, deductibles and exclusions before you decide.

Do I need uninsured motorist coverage?

In many states it is required or strongly recommended. It protects you when the other driver has no insurance or too little.
