Auto insurance is a group of coverages, not a single promise to pay for every car problem. Understanding the parts makes it easier to compare quotes.
What each part generally does
Liability helps pay for covered injuries or property damage you cause to others, up to your policy limits. It generally does not pay to repair your own car. States set different requirements, and the minimum required amount may be less than the cost of a serious accident.
Collision generally helps repair or replace your car after a covered crash with another vehicle or object, subject to a deductible. Comprehensive generally covers certain non-collision losses, such as theft, fire, or hail, also subject to policy terms and often a deductible. A lender may require physical-damage coverage while you have a car loan.
Compare like for like
Use the same liability limits and deductibles when you request quotes. Ask about uninsured or underinsured motorist coverage, medical-related coverage, exclusions, and optional benefits available where you live. Check whether drivers in your household are listed correctly.
Before increasing a deductible to lower the premium, decide whether you could pay that amount after an accident. Revisit coverage when the car’s value or your finances change, and confirm any lender requirements before removing coverage.
