Vehicle wind deflectors are disclosed herein which are carried on the cab or tractor of a semi-trailer combination and carried on the rear end of the trailer. The cab or tractor deflector includes a base mounting for supporting a panel at an angle so as to deflect ram air immediately ahead of the trailer. The trailer rear end deflectors include a pair of elongated deflectors carried at the opposite corners of the trailer wherein each deflector is arcuate in cross section so as to wrap around the corner in fixed spaced relationship to the structure of the trailer to define an air passageway therebetween. Associated with rear deflector, there is a plurality of air spreaders or pipes which accept a portion of the deflected ram air and conduct the air to given areas at the rear of the trailer to break the creation of any vacuum. Angled flanges are disposed at the entrance to each of said spreaders or pipes to catch and direct ram air into the spreaders or pipes.
