[True / False · Hard]

Answer: ✕ False

Explanation

The Rules of the Road, Chapter 3, Section 2, 3(1) states: "It must be a bicycle with four or fewer wheels." The question states "three or fewer wheels," but the correct requirement is "four or fewer wheels." All other requirements are correctly stated.
