According to the definition of a highway, which of the following applies?

The definition of a highway generally encompasses a broader scope than just what is visible on the surface. The correct choice points to the area known as the right-of-way, which includes not only the road itself but also the land adjacent to it that can be used for various purposes. This definition reflects how highways can serve multiple functions and accommodate different forms of traffic, including vehicles, bicycles, and sometimes even pedestrians.

In contrast, the focus on only asphalt surfaces or exclusive private roads does not align with the legal or operational definitions typically used for highways. A highway is not limited to materials or classifications; instead, it is about the designated space for travel. Moreover, while pedestrian paths have their own significance, they do not fall within the standard definition of a highway unless they are part of a broader roadway or transportation network.
