What does a flashing yellow light indicate?

A flashing yellow light indicates that drivers should slow down and proceed with caution. This signal warns you that there may be a hazard ahead or that you are approaching an intersection where you should be alert. It does not require a full stop, allowing for a more fluid flow of traffic while ensuring that drivers remain aware of their surroundings. By slowing down, drivers can better assess the situation, whether it involves pedestrians crossing, road conditions, or other potential dangers. Understanding this signal is crucial for maintaining safety on the road.

The other options do not accurately reflect the purpose of a flashing yellow light. A command to stop immediately does not apply in this scenario, as does the idea of speeding up or preparing to change lanes without regard for caution. Both would disregard the potential hazards indicated by the flashing yellow signal.
