What does a flashing yellow light mean?

Answer: B — Proceed with caution

A flashing yellow light indicates that drivers should proceed with caution. It serves as a warning, alerting them to a potentially hazardous situation ahead, such as an intersection where vehicles may be crossing or pedestrian activity may be present. Drivers are not required to come to a complete stop, but they should slow down, remain vigilant, and prepare to respond to any unexpected situations that may arise, such as the presence of other vehicles or pedestrians. This signal is designed to promote safety while allowing for continued movement through the area. The other options imply immediate actions that are not appropriate for a flashing yellow light. Stopping immediately or yielding to other vehicles suggests situations of higher concern, such as red lights or stop signs, while preparing to turn indicates a different scenario that may not necessarily apply when a flashing yellow light is present.
