Auto Insurance: Complete Guide to Coverage, Costs, and Requirements
Auto insurance protects you financially if you're in an accident, your car is damaged, or you're sued for injuries or property damage. Every state except New Hampshire requires drivers to carry minimum liability coverage.
Understanding what auto insurance covers, what it costs, and how to choose the right policy can save you thousands of dollars while ensuring you have the protection you need. This guide explains everything you need to know.
What Is Auto Insurance?
Auto insurance is a contract between you and an insurance company. You pay a premium, and in return, the insurer agrees to pay for specific losses as outlined in your policy. These losses can include damage to your vehicle, injuries to you or others, and legal liability if you cause an accident.
Most auto insurance policies include several types of coverage bundled together. You can customize your policy by choosing coverage limits, deductibles, and optional coverages based on your needs and budget.
Types of Auto Insurance Coverage
Liability Coverage (Required in Most States)
Liability coverage pays for injuries and property damage you cause to others in an accident. It includes two components:
- Bodily Injury Liability: Covers medical expenses, lost wages, and legal fees if you injure someone in an accident.
- Property Damage Liability: Covers damage to other people's vehicles, buildings, fences, or property.
Collision Coverage (Optional)
Collision coverage pays to repair or replace your vehicle if it's damaged in an accident with another vehicle or object, regardless of who's at fault. This coverage requires a deductible—the amount you pay before insurance kicks in.
Comprehensive Coverage (Optional)
Comprehensive coverage pays for damage to your vehicle from non-collision events like theft, vandalism, fire, hail, flooding, hitting an animal, or falling objects. It also requires a deductible.
Uninsured/Underinsured Motorist Coverage
This coverage protects you if you're hit by a driver who has no insurance or insufficient coverage to pay for your injuries and damages. It's required in some states and highly recommended in all others.
Personal Injury Protection (PIP) / Medical Payments
PIP (required in no-fault states) or Medical Payments coverage pays for your medical expenses and sometimes lost wages, regardless of who caused the accident. PIP typically covers more than MedPay.
What "Full Coverage" Really Means
"Full coverage" is not an official insurance term. It typically refers to a policy that includes liability, collision, and comprehensive coverage. However, it doesn't mean everything is covered—you'll still have deductibles, coverage limits, and exclusions.
What Auto Insurance Does NOT Cover
- Damage to your own vehicle if you only have liability coverage
Liability only pays for damage you cause to others, not your own car.
- Intentional damage or illegal activity
Insurance won't cover damage you cause on purpose or while committing a crime.
- Normal wear and tear or mechanical breakdowns
Auto insurance covers sudden accidents, not maintenance issues or engine failures.
- Personal belongings stolen from your car
Your homeowners or renters insurance covers personal items, not your auto policy.
- Rideshare driving without commercial coverage
Personal auto policies exclude coverage when you're driving for Uber, Lyft, or delivery services.
What Affects Your Auto Insurance Cost?
Your Driving Record
Accidents, speeding tickets, DUIs, and other violations significantly increase your rates. A clean driving record earns you the best rates.
Your Vehicle
Expensive cars, high-performance vehicles, and cars with high theft rates cost more to insure. Safety features and anti-theft devices can lower your rate.
Your Location
Urban areas with higher accident rates, theft, and vandalism have higher premiums than rural areas. Your state's minimum requirements also affect cost.
Coverage Limits and Deductibles
Higher coverage limits increase your premium. Higher deductibles lower your premium but mean you pay more out of pocket if you file a claim.
Your Age and Experience
Young drivers (under 25) and new drivers pay more due to higher accident risk. Rates typically decrease as you gain experience and reach age 25.
Your Credit Score (in Most States)
Insurers use credit-based insurance scores to predict claim likelihood. Better credit typically means lower rates, though some states prohibit this practice.
Common Auto Insurance Mistakes to Avoid
- Buying only minimum liability coverage:
State minimums are often too low to protect your assets. If you cause a serious accident, you could be personally liable for damages beyond your coverage limits.
- Not comparing quotes from multiple carriers:
Rates vary significantly between insurers. Comparing quotes can save you hundreds of dollars per year for the same coverage.
- Letting your coverage lapse:
Even a short gap in coverage can result in higher rates, license suspension, and fines. Set up automatic payments to avoid lapses.
- Not asking about discounts:
Most insurers offer discounts for bundling policies, safe driving, good grades (for students), military service, and more. Always ask what's available.
- Choosing a deductible you can't afford:
A high deductible lowers your premium, but if you can't pay it when you need to file a claim, your insurance is useless.
Frequently Asked Questions
How much auto insurance do I need?
At minimum, carry your state's required liability limits. However, most experts recommend at least 100/300/100 coverage (100k per person, 300k per accident for bodily injury, 100k for property damage) to adequately protect your assets. If you have significant assets, consider higher limits or an umbrella policy.
Does auto insurance follow the car or the driver?
Auto insurance primarily follows the car, not the driver. If someone borrows your car with permission and has an accident, your insurance is primary. However, if you drive someone else's car, their insurance covers you first, and your policy may provide secondary coverage.
Will my rates go up if I file a claim?
It depends on the type of claim and your insurer's policies. At-fault accidents typically increase your rates, while comprehensive claims (theft, hail, hitting a deer) may not. Some insurers offer accident forgiveness for your first at-fault accident.
Can I get auto insurance with a suspended license?
It's difficult but not impossible. Some insurers offer policies for drivers with suspended licenses, but rates will be significantly higher. You may need to file an SR-22 or FR-44 certificate depending on your state and the reason for suspension.
How often should I shop for auto insurance?
Compare quotes at least once a year, ideally 30-45 days before your policy renews. Your circumstances change, insurers adjust their rates, and you may qualify for new discounts. Shopping annually ensures you're getting the best rate.
