What should drivers do when they see a flashing yellow traffic light?

Answer: B — Proceed with caution

When drivers encounter a flashing yellow traffic light, they should proceed with caution. This signal indicates that there may be a potential hazard or the need to be vigilant in that area, such as near construction zones, pedestrians, or intersections where other traffic may have the right of way. It does not require a full stop; instead, it prompts drivers to be more alert and to continue driving carefully while being ready to react to any unexpected situations. This cautious approach helps maintain safety on the road, ensuring that drivers remain aware of their surroundings and can respond appropriately to any changes in traffic conditions or obstacles.
