The definition of comprehensive coverage is insurance designed to help you pay for repairs caused by anything other than a collision. It is typically purchased together with collision coverage as part of full coverage car insurance. If you're leasing your car or still making payments, your lending institution may require you to have this level of coverage, even if your state doesn’t.
It’s typically a good idea to include this coverage in your policy, especially if you have a newly bought or high-value car. You can make a comprehensive insurance claim if your vehicle is damaged by something other than a collision with another car.
