What does a flashing yellow light indicate?

A flashing yellow light indicates that drivers should proceed with caution. This signal is used to alert drivers to a situation that requires them to be more attentive, but it does not require them to stop. Instead, it allows them to continue driving while remaining aware of their surroundings and prepared for anything that may change, such as pedestrians, construction, or other vehicles. This is an essential tool in managing traffic safety because it communicates that something needs attention but does not necessitate a complete stop, allowing for a smoother flow of traffic while ensuring caution is maintained.
