Motorcycles attract a small but dedicated portion of the commercial vehicle market. Because of their small size and lack of protection, motorcycles can be more dangerous that other vehicles. Riders should wear all proper gear, including a helmet, and ride aware of their surroundings.
Most of the automobile industry is comprised of cars, trucks, vans, and SUVs for personal use. While the US car industry and the "Big Three" (Ford, GM, and Chrysler) dominated the industry for many years, increased globalization in recent years has led to a more competitive market for foreign makes and models.
The trucking industry uses large trailers, often called 18-wheelers, to transport everything from produce to clothing to other vehicles.
