What is auto insurance?
Auto insurance is a contract between you and an insurance company. You pay a premium and the insurer agrees to pay for certain losses tied to owning and driving a car, up to the limits in your policy. Those losses can include damage you cause to others, repairs to your own car and medical bills after a crash.
A car insurance policy is really a bundle of separate coverages. Some are required by your state. Others are optional but often worth having, especially if your car is financed or leased or if you'd struggle to pay for a major repair out of pocket.
Is car insurance required?
Nearly every state requires drivers to carry a minimum amount of liability insurance or show they can pay for damages another way, such as a bond or deposit. Minimum limits vary widely by state and they are often lower than the cost of a serious accident.
If your car is financed or leased, your lender will usually require collision and comprehensive coverage as well, because the car is their collateral. Driving without required insurance can lead to fines, a suspended license and paying for damages yourself.

Liability coverage
Liability coverage pays for injuries and property damage you cause to other people when you're at fault. It has two parts. Bodily injury liability helps pay medical bills, lost wages and legal costs for people you injure. Property damage liability helps pay to repair or replace their car, fence or other property.
Liability limits are often written as three numbers, such as 50/100/50. That means up to $50,000 per injured person, $100,000 total for injuries in one accident and $50,000 for property damage. If damages go beyond your limits, you could be responsible for the rest. That's why many drivers choose limits well above the state minimum and some add an umbrella policy for claims that go past those limits.
In most cases, your liability coverage follows you when you drive a borrowed or rental car with permission and it covers others who drive your car with permission. Policy terms vary, so ask how yours handles occasional drivers.
Collision coverage
Collision coverage helps pay to repair your car after it collides with another vehicle or an object, like a pole, guardrail or tree. It can also apply if your car rolls over. Collision pays up to your car's actual cash value, minus your deductible.
A higher deductible usually means a lower premium, but you'll pay more out of pocket if you file a claim. On an older car with low value, some drivers drop collision coverage. We can help you weigh what you'd pay against what the car is worth.
Comprehensive coverage
Comprehensive coverage, sometimes called "other than collision," pays for damage from events like theft, vandalism, fire, hail, windstorms, flooding, falling trees and hitting an animal. Like collision, it pays up to your car's actual cash value minus your deductible. No state requires it, but lenders usually do.
When people say "full coverage," they usually mean liability plus collision and comprehensive. It's not an official policy type, so it's worth checking exactly what's included.
Glass coverage
Windshield and window damage is usually covered under comprehensive. Some policies offer full glass coverage with no deductible or let you add it for an extra cost. If you drive often on highways or gravel roads, it's worth asking about.
Medical payments and personal injury protection
Medical payments coverage, often called MedPay, helps pay medical bills for you and your passengers after an accident, no matter who caused it. Personal injury protection or PIP, is broader. Depending on your state, PIP can also help with lost income and other costs like help at home while you recover.
About a dozen states use a no-fault system that requires PIP. In those states, your own policy pays your injury costs first, regardless of fault. MedPay and PIP rules differ a lot by state, so we'll explain what applies where you live.
Uninsured and underinsured motorist coverage
Not every driver carries insurance and many carry only the minimum. Uninsured motorist coverage helps pay for your injuries and in some states your car, when an at-fault driver has no insurance or in some hit-and-run accidents. Underinsured motorist coverage helps when the at-fault driver's limits aren't enough to cover your costs.
Some states require this coverage. Even where it's optional, it's one of the most useful protections you can add.
Optional add-ons
- Gap insurance: Pays the difference between what you owe on a loan or lease and your car's value if it's totaled or stolen.
- Rental reimbursement: Helps pay for a rental car while yours is in the shop after a covered claim.
- Roadside assistance: Helps with towing, jump-starts, flat tires and lockouts.
- Rideshare coverage: Fills gaps if you drive for a rideshare or delivery app. A personal policy alone may not cover that use.
What affects your car insurance rate?
Insurance companies weigh many factors and each one weighs them differently. That's the main reason comparing quotes matters. Common factors include:
- Your driving record, including accidents and tickets
- Where you live and where the car is parked overnight
- The make, model, year and safety features of your car
- How much you drive and how you use the car
- Your age and years of driving experience
- Your claims history and whether you've had a gap in coverage
- Your credit-based insurance score, in states that allow it
- The coverages, limits and deductibles you choose
How to compare auto insurance quotes the right way
The lowest price only helps if the coverage is close to the same. When we compare car insurance quotes for you, we check:
- That liability limits match or that you understand why they don't.
- That deductibles for collision and comprehensive are the same across quotes.
- Whether uninsured motorist, MedPay or PIP and rental coverage are included.
- How each company treats drivers in your household and any recent tickets.
- Which discounts apply, such as multi-policy, safe driver, good student or paid-in-full.
Ways to lower your auto insurance cost
- Raise your deductible if you could comfortably pay it after a claim.
- Ask about bundling your auto policy with homeowners or renters insurance.
- Keep continuous coverage, since gaps can raise your price.
- Ask about telematics programs that track safe driving, if you're comfortable sharing that data.
- Review your coverage on older cars where collision may cost more than it's worth.
- Shop again at renewal, especially if your price jumped without a claim.
