What does a sign indicating "divided highway ends ahead" mean?

Answer: B — The highway will become a two-way street

The sign indicating "divided highway ends ahead" signifies that the current divided roadway, which offers separate lanes for traffic in opposite directions, is about to transition into a two-way street configuration. This means that drivers should expect an increased likelihood of encountering oncoming traffic in their lane, and they will no longer have the safety of a physical barrier or median separating their direction of travel from the opposite direction. This change requires drivers to be more vigilant and prepared to adjust their driving, as the road conditions and traffic dynamics will shift significantly. Understanding this is crucial for ensuring safety as it alerts drivers to the need for caution in navigating a potentially more complex driving environment.
