ABSTRACT:
An air drag reduction apparatus for a tractor-trailer vehicle including a top fairing panel and a side fairing panel movably mounted on the tractor cab so that the fairing panels are in a stowed position at lower vehicle speeds out of interference with the trailer as the tractor and trailer turn substantially with respect to each other at these lower speeds and in a deployed position at higher vehicle speeds to significantly reduce the air drag on the vehicle normally associated with the air gap between the tractor and trailer.
