What does a red arrow signal indicate?

A red arrow signal indicates that drivers must stop and must not proceed in the direction of the arrow. This traffic signal is used to control the flow of vehicles at intersections, particularly when a turn is involved. When the arrow is red, it conveys a clear message that turning in that direction is prohibited until the signal changes to green or another indicator allows movement.

This rule is important for maintaining safety on the roads, as it helps prevent potential collisions that could occur if drivers turned when they are not permitted to do so. The requirement to stop is in place to ensure that all traffic regulations are obeyed, allowing for a smoother flow of both vehicular and pedestrian traffic when the signal permits movement.
