Vehicles exceeding a substantial mass, specifically 6000 pounds, typically fall into categories such as heavy-duty trucks, specialized commercial vehicles, and certain large sport utility vehicles. These are not standard passenger cars, but rather, are built for tasks demanding significant payload or towing capacity. Examples often include models from manufacturers specializing in robust construction.
The inherent strength and durability associated with these higher-mass vehicles offer benefits in terms of potential accident survivability and the ability to withstand demanding work conditions. Historically, such vehicles have been essential for industries requiring the transport of heavy goods, construction, and agricultural applications. Their presence reflects a need for vehicles capable of handling substantial loads and challenging terrains.
