Which of the following vehicles is classified as an auto cycle?

An auto cycle is defined as a three-wheeled vehicle that has a seating capacity of up to two people and is designed to be operated like a motorcycle. It is characterized by having a steering wheel instead of handlebars, and it typically includes features that enhance comfort and stability while driving.

The three-wheeled scooter falls within this classification as it meets the criteria of having three wheels and is designed primarily for transportation on roadways. This type of vehicle often provides a more enclosed space and can be easier to operate than traditional two-wheeled motorcycles, making it suitable for a range of riders, including those who may not have a motorcycle endorsement.

Other options include types of vehicles that do not fit into the auto cycle category. A standard motorcycle is a two-wheeled vehicle, while a four-wheeled truck does not meet the three-wheel requirement, and a bicycle lacks a motor and does not typically fall under motor vehicle classifications. Therefore, the three-wheeled scooter is the clear choice as it aligns with the definition and characteristics of an auto cycle.
