Final answer:
A driver cannot simply proceed immediately upon a green traffic signal; they must ensure the intersection is safe to navigate, take note of pedestrians and other potential hazards, and act with caution.
Step-by-step explanation:
It is not necessarily true that a driver may proceed immediately when waiting at an intersection and the traffic signal turns green. Drivers must first ensure it is safe to proceed. This includes checking for vehicles that may be running the red light, looking out for pedestrians crossing the intersection, and any other potential hazards. Furthermore, if there is a pedestrian signal at the intersection, the driver should verify that it indicates it is safe for vehicles to go.
In summary, while a green traffic signal generally indicates that drivers can proceed, they must do so with caution and prioritize safety over immediacy.
