Abstract: A cab enclosure for an ATV vehicle is presented. The cab enclosure is made of clear polycarbonate sheets. A lower main frame is rectangular and is bolted onto the front and rear luggage racks of an ATV vehicle. The cab has a clear top, sides, front windshield and rear window so that the operator has an unobstructed field of vision. The cab's lower sides extend to the floor boards. A flexible vinyl flap is attached inside the cab to the front and rear cargo areas of the unit. The flaps are also attached to the rear fenders and snugly fit around the seat, hood, and other areas of the vehicle. The cab provides a virtually unobstructed view to the operator, but also keeps out the rain or snow as well as helping to heat the vehicle by retaining the heat generated by the motor. The cab is easily removed by unfastening the securing bolts and lifting the cab from the ATV vehicle.
