What does a vertical arrangement of three round traffic lights indicate?

In this scenario, the leftmost signal light is for left turns, the middle one is for straight-through turns, and the right one is for right turns. If the signal lights in each direction display green, the direction showing green is permitted to proceed, while red indicates prohibition. Generally, this type of light displays red, yellow, and green from top to bottom. Introduction to Traffic Signals: Traffic signals are lights that direct traffic flow, typically consisting of red, green, and yellow lights. Red indicates prohibition, green indicates permission to proceed, and yellow serves as a warning. Classification of Traffic Signals: Traffic signals are categorized into: motor vehicle signals, non-motor vehicle signals, pedestrian crossing signals, directional indicator signals (arrow signals), lane signals, flashing warning signals, and signals at railway level crossings.
I remember that after driving for so many years, the most common traffic light I've encountered is the vertical arrangement of three circular lights. From top to bottom, they are red, yellow, and green, with very straightforward meanings: you must come to a complete stop when the red light is on, never try to rush through; the yellow light is a warning to prepare to stop, not to speed up; and the green light means it's safe to proceed. This design is intended to be instantly clear to drivers, especially at night or in rainy and foggy conditions, where the vertical alignment and circular shape of the lights make them hard to confuse. In actual driving, I always remind myself to obey it to avoid accidents. I've heard that some beginners mistakenly think the yellow light just means to slow down, but that's dangerous and can easily lead to rear-end collisions. In short, being familiar with this signal is the foundation of safe driving, and it's important to pay close attention to signal changes every time you pass by.
