Auto insurance is required in most states and protects you financially from accidents, theft, and liability. Understanding coverage types and shopping strategies can save hundreds annually while ensuring proper protection.
Required Auto Insurance Coverage
Liability Insurance
Covers damage you cause to others:
Bodily Injury Liability
- Pays for injuries to others when you're at fault
- Covers medical bills, lost wages, legal costs
- Expressed as limits: $50,000 per person/$100,000 per accident
- Required in almost all states
Property Damage Liability
- Pays for damage to others' property
- Covers vehicles, buildings, structures
- Typical minimums: $25,000-50,000
Most experts recommend higher limits than state minimums—100/300/100 is common advice.
Optional but Recommended Coverage
Collision Coverage
- Pays to repair your car after an accident (regardless of fault)
- Subject to deductible ($500-1,000 typical)
- Required if you have a car loan
- May drop on older vehicles
Comprehensive Coverage
- Covers non-collision damage: theft, vandalism, weather, animals
- Subject to deductible
- Required for financed vehicles
- Protects against unpredictable events
Uninsured/Underinsured Motorist
- Covers you if hit by driver without adequate insurance
- About 1 in 8 drivers are uninsured
- Highly recommended even if optional in your state
Medical Payments/Personal Injury Protection

How Much Coverage Do You Need?
Liability
Consider your assets—liability claims can exceed coverage and come after your savings. Recommended minimums:
- 100/300/100 for most drivers
- Higher if significant assets to protect
- Add umbrella insurance for extra protection
Collision and Comprehensive
Drop if car value minus deductible isn't worth protecting. General rule: If coverage costs more than 10% of car's value annually, consider dropping.
Filing a Claim
- Document everything (photos, police report, witness info)
- Contact insurance promptly
- Get repair estimates
- Understand your deductible responsibility
- Know your rental car coverage
