Step-by-step explanation:
Flashing yellow traffic lights mean to slow down and proceed with caution. This statement is true. When approaching a flashing yellow light, drivers should be alert and aware of their surroundings, ready to stop if necessary. The purpose of a flashing yellow light is to ensure that drivers are paying extra attention in potentially hazardous conditions or at busy intersections. Traffic signals are pivotal in managing vehicle and pedestrian traffic, improving safety, and controlling the flow of traffic with varying densities. Installation of traffic signals often follows concerns about multiple issues including speeding vehicles, pedestrian safety, and the high frequency of accidents, all of which can be mitigated by properly functioning traffic controls. Accidents can decrease as drivers are compelled to obey signals, and pedestrians can cross at designated times, increasing overall safety.
