Which of the following best describes motorcycles and mopeds?

• A. They must have no more than three wheels and include a seat for the rider.
• B. They must have at least four wheels.
• C. They are only pedal-powered.
• D. They require a bicycle license.

Answer: (A)

Motorcycles and mopeds are motorized two- or three-wheeled vehicles that have a seat for the rider. That combination of being motorized and having two or three wheels sets them apart from four-wheeled cars and from bicycles, which may be pedal-powered but don’t have a motor in the same way. The options suggesting four wheels or pedal power only don’t fit because motorcycles and mopeds can operate with just two or three wheels and backed by an engine. They also don’t use a bicycle license; riders typically need a motorcycle license or endorsement.
