What defines a traffic lane?

A traffic lane is defined as the specific area of a roadway designated for the movement of vehicles. When considering the choices, the correct response encompasses all lanes that are intended for vehicle travel on any street or highway. This includes general purpose lanes for cars, buses, and trucks, allowing for the orderly and safe movement of traffic.

While designated truck lanes, bike lanes, and emergency lanes serve specific purposes, they are not representative of the broader category of traffic lanes as a whole. Therefore, the definition that covers all lanes for travel on legitimate roadways provides a comprehensive understanding of what constitutes a traffic lane.
