The effect of skew tail-wind on driving safety cannot be ignored. To investigate the effect of skew tail-wind, the aerodynamic characteristics of the vehicle under the action of skew tail-wind were tested by using a wind tunnel test device of the moving vehicle model, aiming at the vehicle and bridge models with the scale ratio of 1/20. The effects of wind speed, wind direction and wind barrier on the aerodynamic characteristic of moving vehicle were discussed. The results show that the five-component coefficients of moving vehicle well agree with different wind speeds. The lateral drag coefficient, lift coefficient and nodding moment coefficient decrease with the increase of the yaw angle. The skew tail-wind has a significantly effect on the lift coefficients when the yaw angle is small. The wind barrier makes the aerodynamic characteristics of the vehicle close to 0, but it obviously transforms the change law of the aerodynamic coefficient of the vehicle with the yaw angle. After the wind barrier is installed, the change rate of drag coefficient of vehicle is affected by the yaw angle, vehicle speed and wind speed.
