What does a red arrow traffic signal indicate?

A red arrow traffic signal serves as a clear directive for drivers regarding their movement at an intersection. Specifically, when you see a red arrow, it means that you must stop and are not allowed to proceed in the direction indicated by the arrow. This signal is designed to enhance safety by preventing drivers from making turns that could conflict with oncoming traffic or pedestrians, thereby helping to regulate the flow of vehicles and improve overall traffic safety at intersections.

A red arrow is distinct from other signals, such as those that allow for cautious movement after yielding, or caution signals that suggest preparing to turn or slow down. It specifically prohibits any movement in that direction until the signal changes. Understanding this signal is crucial for maintaining safe driving practices and adhering to traffic laws.
