An aerodynamic airflow control device is preferably mounted either in a rigi d or slidable manner to an underside of a truck trailer just forward of the trailer tires and axles to better manage airflow around the trailer tire and axle assembly. In operation, the device preferably collects and routs impinging air to exit between the trailer tires and under the trailer axles to reduce road spray while keeping tires and brakes running cooler and while further decreasing parasitic drag of the truck and trailer unit as it moves along the highway.
