Your personal auto insurance policy does not provide coverage for a rented or borrowed truck, van. etc. If you are renting a truck, you should check with the rental company regarding the purchase of collision and comprehensive insurance. If you are borrowing a truck, make sure you determine whether or not the owner has purchased collision or comprehensive insurance coverage. If the owner does not have insurance, you may be personally liable for any damage to that truck which is the result of your negligent operation.
