Final answer:
The correct actions at traffic light signals are to go with caution at a green light, to prepare to stop at a yellow light, and to stop completely at a red light.
Step-by-step explanation:
When approaching traffic lights, each color indicator has a specific action associated with it for drivers and pedestrians to follow in order to maintain safety and efficiency on the roads. At a green light, drivers should proceed through the intersection with caution, staying alert to the surroundings and prepared to stop if conditions change suddenly. On encountering a yellow light, drivers are advised to prepare to stop, as the signal is about to change to red, indicating that the intersection will soon be closed to through traffic. A red light requires drivers to make a complete stop, ensuring both pedestrian safety and the prevention of vehicular accidents. Therefore, the correct action at a green light is to go, at a yellow light is to slow down and prepare to stop, and at a red light is to stop completely.
