What constitutes the boundary lines of a publicly maintained way?

The boundary lines of a publicly maintained way are best described as the lines representing the width of the traveled roadway. This definition captures the practical aspect of what constitutes a public road's limits, focusing on the physical space allocated for vehicular travel and operation. It's essential to understand that these boundary lines are critical for traffic regulation, ensuring that vehicles operate within designated areas to maintain order and safety on public roads.

The lines marking the width of the traveled roadway provide a clear understanding of where vehicles should travel, including considerations for safety, such as ensuring adequate space for passing and maneuvering. Furthermore, this delineation helps law enforcement and traffic management effectively monitor and enforce regulations within their boundaries.

Other options do not accurately define the specific physical parameters of a roadway. For instance, while the edges of urban development or property ownership lines may provide context for roads, they do not specifically define where the road itself begins or ends. Similarly, bike lanes, while an essential component of traffic infrastructure, pertain to specific areas within the roadway rather than establishing the overall boundary lines of the roadway.
