Step Deck
A flatbed trailer with a lower deck section that drops down after the gooseneck, providing extra vertical clearance for taller freight. The upper deck connects to the tractor while the lower deck sits closer to the ground, allowing loads up to approximately 10 feet tall without requiring oversize permits. Step decks are also called drop-deck trailers.
