Your Guide to Buying Auto Insurance

Coverage you want

Options choices

Collision and comprehensive. Collision coverage pays to repair or replace your car no matter who or what caused the accident. Comprehensive pays to repair or replace your car if it's stolen or damaged as a result of a storm or other natural event. Coverage kicks in for the amount above your deductible. Choose the highest deductible you can afford to pay out of pocket—at least $500. Once the cost of this coverage equals 10 percent of your vehicle's book value, you might want to cancel it, since you will collect no more than your vehicle's market worth. Antique vehicles or cars with collector value sometimes are insured through a separate rider; or you may have to find a separate, specialty insurer.

Medical-payments coverage. Sometimes called med-pay, this covers medical bills for you and your passengers, regardless of who's at fault. When this coverage isn't automatically included in your policy, its costs are minimal. You may not require any if you have good health insurance. To protect passengers who may not have their own health coverage, you may want to carry at least $5,000 of this coverage.

Personal-injury protection. PIP reimburses you for lost wages and in-home care needed as a result of an accident. If you have separate health and disability policies, you can buy just the state-required minimum for PIP. The other policies should cover the balance of your needs.
