What does a flashing yellow light mean?

A flashing yellow light indicates that drivers should proceed with caution. It is a warning signal that alerts drivers to be attentive and prepared to yield or stop if necessary. Unlike a steady yellow light, which typically advises a driver to prepare to stop, a flashing yellow light suggests that there may be unexpected factors or hazards present, such as pedestrians crossing or vehicles merging.

This understanding is fundamental for safe driving, as it promotes alertness and encourages drivers to watch for changes in the traffic environment. The requirement to be cautious allows for better decision-making in potentially ambiguous situations, ensuring that drivers can react appropriately to emerging hazards.
