An air drag reduction apparatus attaches to the rear of vehicles having a generally rectangular rear end, such as tractor trailers, busses, and recreational vehicles. A left side roller is mounted in a generally vertical orientation to the rear of the vehicle and a right side roller is mounted in a generally vertical orientation to the rear of the vehicle, where the left side roller and the right side roller are each rotatable about a vertical axis. The left side roller and the right side roller may be mounted with attachment mechanisms which allow the rollers to each be moved out of the way as the rear door or doors of the vehicle are opened.
