What does it mean if a yellow light is flashing at an intersection?

When a yellow light is flashing at an intersection, it is an important signal for drivers to proceed with caution. This means that while it is permissible to continue through the intersection, one must be alert and prepared to stop if necessary. The flashing yellow light indicates that there may be a potential hazard, such as pedestrians crossing or vehicles making turns, thus requiring vigilance from drivers.

Understanding the use of a flashing yellow light is crucial for maintaining safety on the roads. It informs drivers that they should not treat the intersection as completely safe or clear, as there may be other factors in play that necessitate a careful and slower approach. This cautious approach ensures that drivers can react appropriately to any unexpected situations that may arise at the intersection, such as other vehicles or pedestrians.
