Types of Automobile Insurance Coverage
Understanding the different types of auto insurance coverage is essential for building a policy that meets your specific needs. Here are the primary coverage options available in the United States:
Liability Coverage
Liability insurance covers costs associated with injuries and property damage you cause to others in an accident. It includes:
- Bodily injury liability: Covers medical expenses, lost wages, and legal fees if you injure someone
- Property damage liability: Pays for damage you cause to another person’s property
This coverage is mandatory in nearly all states, though required minimum limits vary significantly.
Collision Coverage
Collision coverage pays for damage to your vehicle when you hit another vehicle or object, regardless of who’s at fault. This coverage typically comes with a deductible—the amount you pay before your insurance kicks in.
While not legally required, lenders and leasing companies usually mandate this coverage to protect their investment in your vehicle.
Comprehensive Coverage
Also known as “other than collision” coverage, comprehensive insurance covers damage to your car from incidents other than collisions, including:
- Theft and vandalism
- Natural disasters and weather events
- Falling objects
- Animal collisions
- Fire damage
Like collision coverage, comprehensive typically includes a deductible and is often required by lenders.
Uninsured/Underinsured Motorist Coverage
This coverage protects you when you’re in an accident with a driver who either has no insurance or insufficient coverage to pay for your damages and medical expenses.
Many states require this coverage, recognizing the financial risk posed by the significant number of uninsured drivers on American roads.
Personal Injury Protection (PIP)
Personal Injury Protection covers medical expenses for you and your passengers regardless of who caused the accident. It may also cover:
- Lost wages due to injury
- Rehabilitation costs
- Funeral expenses
- Replacement services (like childcare)
PIP is required in “no-fault” insurance states and optional in others.
Additional Coverage Options
Beyond the standard coverages, you can customize your automobile insurance with these options:
- Gap insurance: Covers the difference between your car’s value and what you owe
- Rental car coverage: Pays for a rental while your car is being repaired
- Roadside assistance: Provides help with breakdowns, flat tires, and lockouts
- Custom equipment coverage: Protects aftermarket additions to your vehicle

Frequently Asked Questions About Automobile Insurance
What happens if I drive without insurance?
Driving without insurance in the United States can result in serious consequences, including:
- Fines ranging from 0 to ,000 depending on the state
- License suspension and vehicle registration revocation
- Potential vehicle impoundment
- Requirement to file an SR-22 (proof of insurance)
- Personal financial liability for all damages in an accident
- Higher insurance rates in the future
Does my credit score affect my automobile insurance rates?
Yes, in most states, insurance companies use credit-based insurance scores as a rating factor. Studies have shown correlation between credit history and claims filing. However, California, Hawaii, Massachusetts, and Michigan have restrictions on using credit information for insurance rating.
Will my rates increase after an accident?
In most cases, yes. At-fault accidents typically lead to premium increases at renewal time. The amount of increase depends on the severity of the accident, your previous driving record, and your insurance company’s specific rating policies. Some insurers offer accident forgiveness programs that prevent rate increases after your first accident.
Does automobile insurance cover me when I drive someone else’s car?
Generally, your personal auto insurance follows you when you drive another person’s vehicle with their permission. However, your coverage is typically secondary to the vehicle owner’s insurance. Coverage limitations may apply, particularly for rental cars or if you drive someone else’s car regularly. Check your specific policy for details.
How do deductibles work?
A deductible is the amount you pay out-of-pocket before your insurance coverage kicks in. For example, with a 0 deductible, you would pay the first 0 of a covered repair, and your insurance would cover the rest. Higher deductibles generally result in lower premiums, while lower deductibles mean higher premiums but less out-of-pocket expense when filing a claim.
