What does a red arrow at a traffic light indicate?

A red arrow at a traffic light indicates that drivers must stop and are not permitted to proceed in the direction the arrow is pointing. This signal is used to control traffic and enhance safety at intersections. The purpose of the red arrow is to prevent vehicles from turning or moving in that direction until the light changes, ensuring that oncoming traffic and pedestrians can safely proceed.

When faced with a red arrow, drivers should remain stopped until the light turns green or the arrow changes, at which point they may move in the direction of the arrow, provided the intersection is clear of obstacles and pedestrians. Understanding the meaning of traffic signals, including red arrows, is crucial for maintaining road safety and following the rules of the road.
