Each insurance company's guidelines regarding covered drivers is different. The owner/ financer of the truck should check with his insurance company to see if you need to be listed on the policy in order to be covered. If you are not listed on the policy but need to be there may be no coverage for you driving the truck. It's a good idea for you to be listed in any event to eliminate any doubt as to whether you would be covered.
