Liability insurance covers you if you’re in an accident deemed to be your fault. It will cover repairs to damaged property, as well as medical bills resulting from injury to the other driver and his or her passengers. Most states require at least a minimum amount of liability insurance, but it’s a good idea to purchase extra protection if you can afford it.
Collision coverage has a deductible, which is the amount you pay before your coverage helps pay for your claim. You can typically choose the amount of your deductible when you buy coverage. So, if you choose a $1,000 deductible and your car is later damaged in a covered accident, you'd have to pay $1,000 toward repair costs. Your collision coverage would help pay the rest, up to your coverage limit.
