ABSTRACT:
A plurality of spaced louvers in an airflow control system on top of a tractor cab open up to permit a flow of air to impinge on the front face of the trailer to exert a braking force to augment the braking force exerted by the wheel brakes to slow down the tractor-trailer assembly. The louvers are under the control of the operator to be responsive to manual control, or to selective automatic control from the brake pedal, accelerator pedal, engine operation, or other vehicle operational equipment.
