Final answer:
The correct action at a flashing yellow light is to slow down and proceed with caution, as it indicates that you should be alert for potential hazards. This cautionary approach is especially important for pedestrian safety and in areas with a high number of accidents. So, the correct answer is option c.
Step-by-step explanation:
When approaching an intersection with a flashing yellow light, the correct action to take is to slow down and proceed with caution. This approach is in contrast to a solid red light or a flashing red light, which would require a complete stop. The flashing yellow light serves as a warning that you should be prepared for potential hazards, such as crossing pedestrians, oncoming traffic, or other situations that might require you to stop or yield.
Maintaining your normal speed without awareness could lead to dangerous situations, especially in areas where pedestrian safety is a concern or where the number of accidents is high. Therefore, a traffic signal is important to regulate the speed of vehicles and ensure the safety of all road users.
So, the correct answer is option c.
