What Is Auto Insurance?
Auto insurance is a contract between you and an insurance company that protects you financially in the event of an accident, theft, or other damage involving your vehicle. In exchange for a monthly or annual premium, the insurer agrees to cover certain costs depending on the type of coverage you have purchased.
Most states require drivers to carry at least a minimum level of auto insurance. Driving without insurance can result in fines, license suspension, and serious financial liability if you cause an accident.
Types of Auto Insurance Coverage Explained
Liability Coverage — The Foundation of Auto Insurance
Liability coverage pays for damage you cause to other people and their property in an accident you are found responsible for. It has two components:
- Bodily injury liability — Covers medical expenses for people you injure
- Property damage liability — Covers damage to another person’s vehicle or property
Collision Coverage
Covers damage to your own vehicle after a collision — regardless of who is at fault. This is particularly important if you have a newer or higher-value vehicle.
Comprehensive Coverage
Covers non-collision damage to your vehicle including theft, vandalism, natural disasters, falling objects, and animal collisions. Often required by lenders if you have a car loan.
Uninsured/Underinsured Motorist Coverage
Protects you if you are hit by a driver who has no insurance or insufficient coverage to pay for your damages. Given that approximately 1 in 8 US drivers are uninsured, this coverage is highly recommended.
Personal Injury Protection (PIP)
Covers medical expenses for you and your passengers regardless of fault. Required in some states, optional in others.
What Auto Insurance Is Required by Law in the US?
Nearly every US state requires at minimum:
- Bodily injury liability coverage
- Property damage liability coverage
Some states also require uninsured motorist coverage and personal injury protection. Requirements and minimum limits vary by state — check your state’s DMV or the Insurance Information Institute for your state’s specific requirements.

Frequently Asked Questions
How much auto insurance do I need?
State minimums are a legal requirement but often not enough to protect you financially. Most financial experts recommend liability limits of at least $100,000 per person and $300,000 per accident, plus collision and comprehensive if your vehicle has significant value.
Does my credit score affect my auto insurance rate?
In most states, yes. Insurers use credit-based insurance scores as a predictor of claims. Improving your credit score can meaningfully reduce your auto insurance premiums over time.
Can I get auto insurance with a bad driving record?
Yes, but you will pay significantly higher premiums. High-risk auto insurance is available, and your rates will typically improve after 3-5 years of clean driving.
