Lane reversal signals are typically used on busy roadways to manage traffic flow during peak hours. These overhead signals display arrows or “X” symbols to indicate whether a lane is open, closed, or changing direction. Drivers must know how to respond promptly: a green arrow means the lane is open, a red “X” means it is closed, and a yellow “X” warns that the lane status is about to change. Mastery of these signals is essential for safe driving.
