What distinguishes a Dual-Arrow Signal Section?

• A. It has only one arrow for traffic control
• B. It includes both a yellow arrow and a green arrow
• C. It operates only during peak hours
• D. It is used exclusively for pedestrian signals

Answer: (B)

A Dual-Arrow Signal Section is characterized by its inclusion of both yellow and green arrows that provide specific indications to drivers. The green arrow signals that a driver can proceed in the direction indicated by the arrow, while the yellow arrow warns that the signal is about to change and that the driver should prepare to stop if it is safe to do so. This functionality is crucial for managing traffic flow at intersections where left turns are permitted, allowing for better communication of right-of-way and enhancing overall safety on the roads. The presence of both arrows in this signal section aids in reducing confusion among drivers and improves decision-making at critical points in traffic. This feature helps ensure that participants in the traffic system have clear and actionable information about their movements, which is fundamentally different from having only a single arrow or being limited to specific operating hours or pedestrian use.
