What is the term for the part of a highway that is designed for vehicular travel, excluding the berm or shoulder?

The term that refers specifically to the part of a highway designated for vehicular travel, excluding the berm or shoulder, is "roadway." This definition indicates that the roadway is the main area where vehicles operate, providing a clear distinction from other components of the highway such as shoulders, which are the areas on either side of the road meant for emergencies or breakdowns. Understanding this distinction is important for various aspects of motor vehicle law and safe driving practices.

The other choices, while related to road infrastructure, do not accurately define the specific area intended for vehicular travel. A freeway typically refers to a high-capacity road that is designed for fast-moving vehicles and eliminates at-grade intersections but is a type of roadway rather than a general term. A pathway usually indicates a route designated primarily for pedestrian use or non-motorized vehicles, while a lane refers to a division of the roadway that provides space for a single line of vehicles, which does not encompass the entire roadway itself. Therefore, the proper term for the part of the highway designed for vehicular travel is indeed "roadway."
