In this study, surface pressure and drag measurements were conducted for a heavy vehicle model consisted of 1/32 scaled truck and trailer which was placed in a wind tunnel. The wind tunnel tests of truck trailer combination were carried out in the range of 117 000 - 844 000 Reynolds numbers. The pressure coefficient (CP) distribution and aerodynamic drag coefficient (CD) on truck and trailer were experimentally determined. The regions forming aerodynamic drag on the truck trailer was determined at the result of the flow visualization. The average drag coefficient (CD) was determined as 0.608 for truck. The drag coefficiens was obtained as 0,704 for truc trailer combination. The drag coefficient (CD ) increased 15.8%, when the trailer was attached to the truck.
