That makes price important—but price shouldn’t be the only consideration.
A low-cost policy with insufficient liability protection or a very high deductible could create substantial financial exposure after an accident.
The better approach is to compare both coverage and price.
What Does Auto Insurance Cover?
An auto insurance policy can contain several different types of coverage.
Bodily Injury Liability
This can help pay eligible costs when you’re legally responsible for injuries to another person in an accident.
Property Damage Liability
This can help cover eligible damage you cause to another person’s vehicle or property.
Collision Coverage
Collision coverage generally helps pay for eligible damage to your own vehicle resulting from a collision, subject to your deductible and policy terms.
Comprehensive Coverage
Comprehensive coverage generally protects against certain non-collision losses.
Examples can include:
- Theft
- Hail
- Falling objects
- Fire
- Vandalism
- Certain animal-related damage
Coverage varies, so policy terms should always be reviewed.
Uninsured and Underinsured Motorist Coverage
This coverage can provide protection when an at-fault driver has no insurance or insufficient insurance, subject to applicable policy terms and state requirements.
Medical Payments or Personal Injury Protection
Depending on the state and policy, these coverages can help pay eligible medical expenses associated with an accident.
What Does “Full Coverage” Auto Insurance Mean?
“Full coverage” is a commonly used phrase, but it is not one standardized insurance policy.
People often use it to describe a policy containing:
- Liability
- Collision
- Comprehensive
However, actual coverage limits, deductibles and additional protections can still differ substantially.
Instead of asking an insurer only for “full coverage,” specify the coverage types and limits you want to compare.
Why Auto Insurance Rates Vary
Insurance companies use numerous factors when calculating premiums, subject to state regulations.
Factors can include:
- Driving history
- Vehicle
- Location
- Annual mileage
- Coverage limits
- Deductible
- Claims history
- Driver characteristics
- Available discounts
Different insurers can price the same risk differently.
That’s why comparing auto insurance quotes can be valuable even when your current insurer has not changed your coverage.
Liability Limits Matter
State minimum liability requirements should not automatically be interpreted as the ideal amount of financial protection.
Imagine causing a serious accident involving several vehicles.
If damages exceed the liability limit on your policy, you could potentially face substantial personal financial exposure.
When comparing policies, consider the assets and income you want to protect rather than choosing limits solely because they produce the lowest premium.
Choosing an Auto Insurance Deductible
Collision and comprehensive coverage commonly include deductibles.
A higher deductible can reduce the insurance premium, but increases what you must pay after an eligible claim.
For example:
$500 deductible: potentially higher premium, lower immediate claim expense.
$1,000 deductible: potentially lower premium, higher immediate claim expense.
Before increasing your deductible, ask whether you could comfortably pay that amount tomorrow if your vehicle were damaged.
How to Compare Auto Insurance Quotes Correctly
The most useful comparison uses the same coverage for every insurer.
For example:
| Coverage | Insurer A | Insurer B | Insurer C |
|---|---|---|---|
| Bodily Injury Liability | Same Limit | Same Limit | Same Limit |
| Property Damage | Same Limit | Same Limit | Same Limit |
| Collision | Same | Same | Same |
| Comprehensive | Same | Same | Same |
| Deductible | Same | Same | Same |
| Uninsured Motorist | Same | Same | Same |
| Annual Premium | Compare | Compare | Compare |
Without matching the coverage, the cheapest quote may simply provide less protection.
Ways to Potentially Lower Car Insurance Premiums
Compare Multiple Insurers
Rates vary, so periodic comparison can identify other options.
Consider Bundling
Combining home and auto insurance with one insurer may qualify for a multi-policy discount.
Review Your Deductible
A higher deductible may reduce premiums if you can afford the additional claim risk.
Ask About Discounts
Depending on the insurer, discounts may be available for:
- Multiple vehicles
- Safe driving
- Bundled policies
- Certain vehicle safety features
- Low mileage
- Eligible driver programs
Review Coverage on Older Vehicles
As a vehicle loses value, periodically evaluate whether the cost of collision and comprehensive coverage still makes sense relative to the vehicle’s value and your financial situation.
Should You Choose the Cheapest Auto Insurance?
Not automatically.
Price matters, but so do:
- Liability limits
- Deductibles
- Exclusions
- Claims service
- Financial strength
- Optional coverage
- Rental reimbursement
- Roadside assistance
Saving a small amount each month may not be worthwhile if the cheaper policy leaves you with substantially more financial risk.
When Should You Compare Auto Insurance?
Consider reviewing rates when:
- Your policy renews
- You buy a vehicle
- You move
- You add or remove a driver
- Your driving habits change
- You buy a home
- Your insurance premium increases significantly
Even drivers satisfied with their current insurer can use competing quotes as a benchmark.
What Information Do You Need for an Auto Insurance Quote?
Having accurate information ready can make comparisons easier.
Insurers may ask for:
- Driver information
- Vehicle identification information
- Driving history
- Annual mileage
- Address
- Current coverage
- Desired limits
- Deductible preference
Use consistent information for every quote.
A Better Auto Insurance Shopping Strategy
Instead of starting with:
“Who has the cheapest car insurance?”
start with:
“How much coverage do I need?”
Then request several quotes using those same coverage limits.
This separates two decisions that consumers often combine:
Decision 1: How much protection do I need?
Decision 2: Which insurer offers that protection at the best overall value?
That approach creates a much more meaningful comparison.
