How should a driver respond to a red arrow?

When a driver encounters a red arrow, it serves as a signal indicating that they must stop and cannot proceed in the direction the arrow is pointing. This rule is crucial for maintaining safety on the road and ensuring that drivers do not enter an intersection when it is unsafe or against traffic regulations.

By remaining stopped until the green signal appears, drivers ensure they comply with traffic laws and avoid potential accidents that could occur from turning against a red arrow. While other options might seem plausible in certain circumstances, they do not align with the specific directive given by the red arrow, emphasizing the importance of obeying traffic signals as a fundamental rule of the road.
