What does a red arrow mean at an intersection?

A red arrow at an intersection indicates that a driver must stop and is not allowed to turn in the direction of the arrow. This signal is used to control traffic flow and ensure safety at intersections. The presence of the red arrow specifically prohibits any movement in that direction, similar to a solid red light, making it clear to drivers that they must wait until the signal changes to green or the traffic control device indicates otherwise. It's important for drivers to recognize and obey this signal to prevent accidents and maintain orderly traffic movement. Understanding this traffic control device is essential for safe driving and compliance with traffic laws.
