Unlike Liability Insurance, collision and comprehensive insurance coverage are not required by most states. Unless you took out a loan to purchase the vehicle (in which case you are usually required to carry both comprehensive and collision insurance), comprehensive and collision are options you may or may not currently have. Both types of automobile coverage are different in how and when they will protect your vehicle, so knowing what type of coverage you have and what your deductibles are will give you peace of mind in the event of an accident.
