What describes the entire width between boundary lines of a way that is publicly maintained for vehicular travel?

The term that describes the entire width between boundary lines of a way that is publicly maintained for vehicular travel is "highway." In this context, a highway encompasses all of the areas set for the use of vehicles, including lanes, shoulders, and any adjacent rights-of-way that may be used for road activities.

Highways are designed to facilitate efficient movement and provide access for various types of vehicles. This definition is crucial in understanding the legal and operational aspects of vehicle regulations, maintenance responsibilities, and usage rights associated with highways.

While the other terms have specific meanings, they may not encompass the entire concept as thoroughly as "highway." For example, a "roadway" specifically refers to the portion of the road that is actually used for vehicle travel, excluding any shoulders or drainage ditches. Similarly, "parkway" typically refers to a scenic road designed for pleasure driving, often with landscaped aesthetics, rather than a straightforward vehicular thoroughfare. A "street" usually indicates an urban road, which often includes areas for pedestrians and does not typically describe the broader maintained area as fully as a highway does.
