Which of the following should be done if a yellow light is flashing?

When a yellow light is flashing, it indicates that you should prepare to stop and proceed with caution. This warning signals that the traffic light is about to change and that drivers should be alert for potential hazards or pedestrians crossing the road.

By preparing to stop, you ensure that you can respond appropriately to any changes in traffic conditions. Proceeding with caution allows you to gauge the situation better, such as determining if other vehicles are stopping or if pedestrians are present. This practice is crucial for maintaining safety on the road, as it helps prevent accidents and ensures that everyone on the roadway is aware of the changing conditions.

In contrast, actions like speeding up, continuing to drive without slowing down, or changing lanes immediately can lead to dangerous situations, as these behaviors may not account for the presence of other vehicles or pedestrians and could result in collisions. Therefore, understanding the implications of a flashing yellow light and responding appropriately is essential for safe driving.
