Final answer:
False. When a traffic light displays a red light and a green arrow, drivers may turn in the direction of the arrow even while the red light is illuminated, as the green arrow indicates permission to proceed with caution in that direction.
Step-by-step explanation:
If a traffic light shows both a red light and a green arrow, the correct interpretation is that the red light applies to movements which are not indicated by the green arrow. Therefore, when you see a green arrow, it means that you are permitted to proceed in the direction of the arrow, even though the main signal is red. This exception to the red light rule allows for smoother traffic flow and turning maneuvers at busy intersections while maintaining safety. It is important for drivers to understand this so that they do not unnecessarily wait at a green arrow, potentially causing delays and confusion.
The instructions provided by a traffic light are meant to maximize safety and efficiency. For example, at an intersection, traffic signals are used to manage the movement of vehicles and pedestrians, ensuring that everyone can traverse the intersection safely. However, drivers must always remain alert to their surroundings, respecting the posted speed limit and watching for pedestrians and other hazards that might require additional caution.
