What does the term 'highway' refer to?

The term 'highway' refers to the entire width of the boundary lines of every way publicly maintained, which encompasses not just the paved road itself but also any shoulders, medians, and related parts of a roadway. This definition emphasizes the full extent of the roadway that is under public maintenance, highlighting its role as a thoroughfare for all types of vehicles and pedestrians.

Understanding this definition is crucial for law enforcement and road safety regulations, as it clarifies jurisdiction and responsibility in traffic management, maintenance, and enforcement of laws related to public roads. The other options are narrower in scope and do not capture the full legal definition of a highway, which includes all publicly maintained ways rather than limiting it to just long-distance travel or local traffic.
