A flashing amber (yellow) signal light at an intersection means what?

A flashing amber (yellow) signal light at an intersection indicates that drivers should slow down and drive with increased caution. This type of signal is a warning that there may be a change in the traffic situation or that there may be vehicles, pedestrians, or other potential hazards present at the intersection. Unlike a solid red light, which requires a complete stop, or a green light, which permits movement, the flashing amber light serves as a signal to proceed, but advises drivers to be vigilant and prepared to react to any potential danger or unexpected circumstances.

This cautionary measure is vital for maintaining safety on the road, as it encourages drivers to be more alert when navigating intersections where they may need to yield to others or adjust their speed according to conditions. Understanding this signal is crucial for ensuring proper responses while driving.
