foxnews.com – (Polaris) Next With three wheels, the open-top Polaris Slingshot is part car and part motorcycle. But in one state it’s neither. The sporty two-seater has two wheels in the front and one in the rear, which in most states qualifies it as a motorcycle. Some require a motorcycle license and the use of helmets to operate it, while others let you drive with a standard automobile license. But neither is the case in Texas, where regulators have reversed an earlier decision to classify it as a motorcycle after revisiting the regulations that govern this type of vehicle.
