Auto insurance is more than a price on a quote. The coverage you choose determines which losses your policy may respond to, how much protection is available, and what you could still have to pay yourself after an accident.
InsuranceCoverage.net helps U.S. drivers understand coverage types, state insurance requirements, policy limits, deductibles, high-risk insurance situations, and the questions worth asking before comparing quotes.

Compare correctly →What Is Auto Insurance?
Auto insurance is a contract between you and an insurance company. You pay a premium in exchange for the protections provided by the policy, subject to its limits, deductibles, exclusions and other terms.
Most states require drivers to maintain some form of financial responsibility, commonly through liability insurance. The exact required coverages and limits depend on the state. [1]
A policy can also contain optional or lender-required protections for your own vehicle, medical expenses, uninsured drivers, roadside situations and other risks.
Determined largely by your state and, in some situations, financial-responsibility requirements.
Depends on your vehicle, finances, risk tolerance, lender, household and coverage priorities.
Understand What Each Auto Insurance Coverage Does
A policy is made up of separate coverages. Understanding what each part protects is more useful than relying only on labels such as “minimum coverage” or “full coverage.”
Bodily Injury Liability
Helps pay qualifying injury-related losses when you are legally responsible for an accident, subject to your policy limits.
Commonly requiredProperty Damage Liability
Helps pay for qualifying damage you cause to another person’s vehicle or other property.
Commonly requiredCollision
Can pay for covered damage to your own vehicle after a collision, subject to your deductible and policy terms.
Optional by state law*Comprehensive
Covers certain non-collision losses such as theft, hail, vandalism, fire and other covered events. [2]
Optional by state law*Uninsured / Underinsured Motorist
Can protect against qualifying losses involving drivers who have no insurance or insufficient liability coverage.
State rules varyPIP / Medical Coverage
Depending on the state and policy, medical payments or personal injury protection may help with qualifying injury-related expenses.
State rules vary*A lender or leasing company may require collision and comprehensive even when state law does not require them.
Coverage Amount Matters as Much as Coverage Type
Having liability insurance does not mean every covered loss will be paid in full. Each coverage has limits that determine the maximum amount available under the policy for a qualifying claim.
- $50,000 bodily injury per person
- $100,000 bodily injury per accident
- $50,000 property damage per accident
A deductible works differently. It generally represents the amount you are responsible for under a qualifying physical-damage claim before the applicable insurer payment.
Increasing a collision or comprehensive deductible can reduce premium, but it also increases your potential out-of-pocket cost after a loss.

Read our Editorial Policy →What Affects Your Car Insurance Rate?
Auto insurers use underwriting and rating to determine eligibility and price. The factors available to an insurer depend partly on state law and the insurer’s approved rating plan. [1]
Driving Record
Accidents, violations and driving history can materially affect the risk an insurer assigns to a driver.
Vehicle
Vehicle value, repair costs, safety characteristics and other vehicle information can affect the cost of coverage.
Location
Insurance losses, traffic, theft and other location-related information can influence pricing where permitted.
Mileage & Use
Annual mileage and how a vehicle is used can affect exposure and insurance pricing.
Coverage Choices
Higher liability limits, additional protections and lower physical-damage deductibles generally change premium.
Credit-Based Insurance Information
Many insurers use credit-based insurance scores in states where the practice is permitted, but state restrictions vary significantly. [3]
Insurance Needs Can Change With Your Driving Situation
A standard shopping strategy may not work equally well for every driver. Some situations require additional research or a different type of policy.
SR-22 & Financial Responsibility
Some states require proof of financial responsibility after certain suspensions or serious violations. Requirements are highly state-specific.
Trying to Lower Premiums
Shopping, coverage choices, deductibles, discounts and driving history can all matter when trying to reduce insurance costs.
Lower your insurance rates →Credit Is a Concern
Credit-based insurance scoring is different from a traditional credit score and state rules determine whether and how it may be used.
Understand no-credit-check insurance →New or Inexperienced Drivers
Driving experience can materially affect insurance eligibility and price, making comparison particularly important for newer drivers.

A $120 quote and a $160 quote do not necessarily represent the same insurance. Before deciding that one insurer is cheaper, confirm that the underlying protection is substantially equivalent.
Questions Worth Asking Before Choosing a Policy
What insurance does my state require?
Are the minimum liability limits enough for my situation?
Does a lender or lease require collision and comprehensive?
What happens if an uninsured driver causes the accident?
Could I comfortably pay the deductible after a claim?
Are all the quotes I am comparing based on equivalent coverage?
Which discounts are actually applied?
When exactly does coverage become effective?
The Policy — Not the Quote Page — Determines Your Coverage
An insurance policy is a legal contract. The declarations page identifies important information such as the insured vehicles, policy term, coverage limits and other policy details. [1]
Auto Insurance Questions
What auto insurance coverage is required?
Requirements vary by state. Liability insurance is commonly required, while some states also require PIP, medical benefits, uninsured motorist coverage or other protections. Check your state-specific requirements rather than relying on a national minimum.
What does “full coverage” mean?
“Full coverage” is an informal term rather than a single standardized policy. It commonly refers to liability insurance combined with collision and comprehensive coverage, but the actual protections and limits still need to be reviewed individually.
Is minimum coverage enough?
Minimum coverage may satisfy the state’s legal requirement but does not necessarily provide enough protection for every driver’s finances or vehicle. Consider the potential size of a loss as well as the legal minimum.
What is the difference between collision and comprehensive?
Collision generally covers qualifying damage to your vehicle from collisions with vehicles or objects. Comprehensive generally covers certain non-collision losses such as theft, weather, vandalism and fire.
Why do car insurance quotes vary so much?
Insurers can use different underwriting rules, rating models, discounts and pricing assumptions. Your driving history, vehicle, location, mileage and coverage selections can also affect the premium.
Does my credit score affect car insurance?
In many states insurers may use a credit-based insurance score as part of underwriting or rating. It is not the same as a traditional credit score, and some states prohibit or restrict its use.
Should I compare only the monthly payment?
No. Compare the full premium together with liability limits, deductibles, optional protections, policy term, fees and discounts. A cheaper payment can represent less coverage.
When does an auto insurance policy actually begin?
Do not assume that completing a quote means you are insured. Confirm that the insurer has accepted the coverage and verify the policy’s effective date and time before relying on it.
Start With the Coverage You Need — Then Compare the Price
Understand your state requirements, choose your limits and deductibles, and compare available auto insurance options on an equivalent basis.
