Explanation:

The "Traffic Signal Ahead" sign indicates that a traffic signal is present but not visible due to obstruction, such as a hill or curve. This sign warns drivers to slow down and prepare to stop if necessary, regardless of the obstruction that may be blocking their view of the signal. It implies that there is indeed a traffic signal ahead, even though it cannot be seen at the moment due to the road's topography or layout.

The presence of a traffic signal aims to improve safety conditions by reducing vehicle speed at intersections and enhancing pedestrian safety, especially in areas with high traffic volume or near campuses. Apart from controlling vehicle flow, these signals are pivotal in preventing accidents and can even save lives by systematically managing the crossing times for pedestrians and vehicles. According to police reports, intersections without such signals can experience a high number of accidents, sometimes with tragic outcomes, which underscores their importance.
