What defines a highway in Indiana?

A highway in Indiana is defined as the entire width between the boundary lines that is open for public travel. This definition encompasses all areas available for vehicles and is not limited to just the paved surface. It includes the shoulders and any adjacent areas that facilitate the overall function of the highway for public transportation.

This distinction is vital because it conveys that a highway encompasses more than just the lanes used for driving; it includes all parts of the roadway that allow for the safe and efficient movement of traffic. Recognizing this full scope of a highway helps ensure that all areas are treated in accordance with traffic laws, including regulations regarding maintenance, usage, and safety.

The other options misrepresent the definition; focusing solely on just the pavement, limiting the definition to only certain roads, or excluding other travel areas does not capture the comprehensive nature of what constitutes a highway in the context of Indiana traffic laws.
