This book will help you deal with the aftermath of collisions involving commercial vehicles. It elaborates, “A commercial vehicle is one that weighs more than 10,000 pounds. They are almost always commonly referred to as trucks and can range from a box truck used locally to deliver packages, to buses, to dump trucks, to concrete mixers, to oil and gas tanker trucks, to 18-wheelers.
“In general, truck accidents refer to anything bigger than a pickup truck. When we talk about commercial vehicles, we're also talking about the trailer they pull. Often the truck/tractor itself will be under 10,000 pounds but the trailer and its load might weigh 8,000 pounds, which will put the total load over 10,000 pounds. It’s the combined weight of the two loads together that make the definition of a commercial vehicle.
“The reason that is significant is because so often, trailers make up the bulk of the weight. They are carrying contents that can easily outweigh the truck and present an array of dangers unassociated with the truck or tractor itself.”
