What does a 'through highway' allow in terms of traffic?

A 'through highway' is designated to provide preferential right-of-way for vehicular traffic. This means that vehicles traveling on the through highway do not have to stop at intersections where they intersect with less significant roads. Instead, vehicles on the through highway have the priority to continue moving, while those on the intersecting road must yield.

This designation helps facilitate smoother and more efficient traffic flow and reduces delays on the major route, enhancing overall travel efficiency. Such highways are often marked with signage indicating that the traffic has the right-of-way, alerting drivers on intersecting roads of their obligation to yield.

Other options present constraints or rules that do not typically apply to the function of a through highway. For instance, the requirement for all traffic to stop at intersections contradicts the primary purpose of a thoroughfare, which is to maintain continual movement. Similarly, the notion that vehicles can enter without yielding does not accurately reflect the mechanics of yielding at intersections shared with a through highway, and the pedestrian right-of-way at all times is not applicable as these laws vary based on the specific intersection design and traffic regulations in place.
