Final answer:
The proper procedure when a traffic light turns green includes checking for clear passage, observing pedestrian safety, and proceeding with caution while adhering to the posted speed limit.
Step-by-step explanation:
When the traffic light turns green, the proper procedure to follow is to first look both ways to ensure the intersection is clear and no other vehicles are running the red light. If pedestrians are present, the driver should wait until they have safely crossed. Additionally, the driver should check for emergency vehicles that may be approaching and have the right of way, such as when there is a pregnant woman being rushed to the hospital. After verifying these conditions, the driver can proceed through the intersection at a safe speed, adhering to the posted speed limit and being mindful of pedestrian safety.
