This bill amends title 49 of the United States Code to establish comprehensive safety standards for autocycles. It defines an autocycle as a three-wheeled motorcycle with front-wheel drive, a fully enclosed occupant compartment, and a steering wheel, which will be subject to federal safety standards determined by the Secretary of Transportation. During an interim period, autocycles must comply with a combination of existing motor vehicle safety standards for passenger cars and motorcycles, covering aspects like controls, brakes, seating, and occupant protection. Key interim requirements include compliance with standards for steering wheel airbags , anti-lock brakes , and electronic stability control . The legislation mandates that the Secretary of Transportation issue final rules for autocycle safety within three years, ensuring appropriate application of both motorcycle and passenger car safety standards while providing manufacturers with adequate lead time for compliance.
