What does a flashing yellow signal at an intersection indicate?

A flashing yellow signal at an intersection indicates that all traffic should slow down and proceed cautiously. This signal is used to alert drivers to be aware of the intersection and any potential hazards that may not be immediately visible. It serves as a warning that conditions may require additional care; for example, there may be pedestrians crossing or vehicles that might enter the intersection unexpectedly.

The significance of the flashing yellow is to encourage drivers to remain alert and prepared to yield to other road users, rather than stopping completely. This contrasts with a solid yellow light or a red light, where stopping is mandatory. Therefore, while caution is always necessary, the flashing yellow does not require drivers to come to a complete stop unless other circumstances dictate it.
