The correct answer is: Warns you to drive with caution

A flashing yellow beacon above an intersection indicates that drivers should approach the area with heightened awareness and proceed with caution. This signal is intended to alert drivers to potential hazards ahead or unusual traffic conditions, encouraging them to slow down and be prepared to stop if necessary. The beacon serves as a warning and is an important traffic control device to help reduce the risk of accidents in areas where heightened vigilance is required. Drivers encountering a flashing yellow light should remain alert for other road signs, pedestrians, or unexpected obstacles that may necessitate a change in speed or direction. Understanding this signal helps ensure safety for all road users.
