Vortex disruption apparatus are permanently or removably installed or attached to cargo and passenger vans, busses, box-trucks, tractor-trailer combinations, or any other vehicle to increase transportation efficiency by reducing drag by minimizing the formation of trailing end vortex flow. A plurality of vortex disruption devices is disposed in proximity to the trailing end of a cargo trailer and in adjacently spaced relation whereby they extend away from the vehicle or trailer surface well beyond the fluid dynamic laminar boundary layer formed as the vehicle passes through the air. Once installed the vortex disruption devices disperse the air flowing over the disrupter while allowing air to flow normally through the spaces between the devices. The vortex disruption devices thereby inhibit the natural convergence of airflow and prevent the formation of a low-pressure vortex beyond the trailing edge of the vehicle.
