So what is a commercial vehicle any way? Is it different than a truck?
Is a "light" commercial = a half thru one ton?
Is a Commercial Car = a Sedan Delivery or Coupe Pickup?
Is a heavy commercial a one ton or larger that Chevrolet calls "Utilitys"?
Is a commercial Spam on your server or a trip to the icebox when watching TV?
. . . . What do you think??

Commercial trucks are rigs that are required to have special permits and licensing to operate unless they are used strictly for show or parades.
