Final answer:
The red arrow at a traffic signal requires only the lane intending to turn in the direction of the arrow to stop, not all lanes of traffic. Other lanes may continue if they have different signals, such as a green light.
Step-by-step explanation:
The question at hand addresses the rules of traffic signals specifically related to a red arrow at an intersection. The correct answer is No, as the red arrow indicates that the turning lane must stop, but it does not necessarily mean that all lanes of traffic must stop. Typically, a red arrow signal is directed at traffic intending to turn in the direction the arrow points. However, if there are other lanes with different signals—for instance, a green light for going straight—those lanes do not need to stop.
It is crucial for drivers to adhere to road signs and signals for the safety of all road users, including pedestrians. Instances where a traffic signal could potentially be disregarded, such as a medical emergency, are exceptional and should be handled with the utmost caution, keeping in mind the risk to other road users.
