What is the definition of "highway" in this context?

The correct definition of "highway" in this context refers to the entire width between the boundary lines of every way that is publicly maintained and open for vehicle travel. This definition emphasizes both the physical space of the roadway and the legal status that allows it to be used by the public for vehicular access. Understanding this definition is crucial, as it encompasses not just the traveled portion of the road, but also the areas adjacent to it that are maintained for public use.

This legal clarity is essential for peace officers, as it helps in enforcing traffic laws, managing roadway safety, and understanding jurisdictional responsibilities. Furthermore, recognizing the scope of what constitutes a highway ensures that officers can accurately assess incidents or violations that occur on these public thoroughfares.

In contrast, other definitions may focus on more narrow aspects, such as specific types of roads or their intended usages, which do not fully capture the comprehensive nature of "highway" as defined in the relevant statutes. Thus, option B provides the most accurate and applicable definition in the context of peace officer training and law enforcement procedures.
