What does a stale green light refer to?

A stale green light refers to a situation where the traffic signal has been green for an extended period. This indicates that it may not be safe to assume that the light will remain green indefinitely. Drivers should be cautious because a stale green light can change to yellow and then red without much warning. Being aware of a stale green light is essential for maintaining safe driving practices, as it encourages drivers to prepare for potential changes in traffic flow, ensuring they can react appropriately to avoid accidents. Understanding this concept helps promote defensive driving habits, especially in busy intersections where traffic patterns may suddenly change.
