Whitney's Truck was a truck owned by Whitney Fordman.
Angry that Clark has a thing with his girlfriend Lana Lang, Whitney throws Clark into the back of his pickup truck and strings him up in Lawson's Field as the scarecrow. Clark later stacks Whitney's and some other trucks on top of each other. Greg Arkin distracts Whitney causing him to lose control of his car and it tumbles. It blows up but Clark blankets himself over Whitney. Whitney uses what is probably a rental later in the episode, but seems to get his truck repaired in three episodes, as he's seen driving it again in "Cool." Whitney follows Clark and drives his truck to Kyle Tippet's trailer, and attacks him. Clark's able to tell it's Whitney by looking at his car.
