In virtually every state, by law you must buy a minimum amount of liability insurance. The state required limits are generally very low and most people should consider purchasing much more than the state requirement—the recommended amount of liability protection is about ten times the average state minimum. If you have a new or recent model of car, you likely will also buy comprehensive and collision coverage, which pays for damage to your car due to weather, theft or physical damage to the car such as being hit by a tree. Comprehensive and collision coverages are subject to deductibles; the higher the deductible, the lower your auto insurance premium. While there is no legal requirement to purchase these coverages, if you finance the purchase of the car or you lease it you may be required by contract.
