To understand the answer to that question you first need to understand the four basic types of liability insurance available to you:
Primary Auto Liability Insurance is the very minimum insurance you should have on your truck and is required in every state. It covers any damage or injuries to other motorists that result in an accident that is considered your fault. It’s important to make sure that you meet limit requirements on this type of insurance.
General Liability Insurance covers your truck when it is not on the road such as when you’re parked on a parking lot, stopping at a restaurant, or loading your vehicle.
Non-owned Trailer Liability & Trailer Interchange covers physical damage to a trailer that you are hauling but do not own while it’s in your possession.
Motor Truck Cargo Liability Insurance covers damage to the freight or commodity that you are hauling in the event of things such as fires, accidents, or temperature issues.
Because each policy is a uniquely different, it’s important to ask questions about which types of insurance you need to protect your business & its assets.
