A flashing yellow traffic light means:

A flashing yellow traffic light indicates that drivers should proceed with caution. This signal alerts drivers that they should be aware of their surroundings and be prepared to yield to any oncoming traffic or pedestrians. It does not require a complete stop, but it does emphasize the need for vigilance as you approach the intersection. The intention is to make sure that drivers are alert and ready to react to potential hazards, unlike a solid green light where it’s safe to proceed without such caution.

While it's important to understand the meanings of other signals, the flashing yellow light specifically informs drivers to be careful and assess the situation before continuing, making it essential for maintaining safety on the road.
