In addition to the three circular signal lights mentioned above, there may also be arrow-shaped signal lights, or a combination of circular and arrow signal lights. For both types of signal lights, the left one corresponds to left turns, the middle one to straight ahead, and the right one to right turns. You may proceed through the intersection when the light corresponding to your intended direction of travel turns green, while directions showing red lights are prohibited.

As a seasoned driver frequently navigating city roads, when I see three vertically arranged traffic lights, I know exactly how to respond: the top one is red, meaning a complete stop is mandatory; the middle yellow light serves as a warning to slow down and prepare to stop—don't even think about rushing through; only the bottom green light indicates it's safe to proceed. This design follows international standards, making the light sequence instantly recognizable, especially during nighttime or rainy conditions when visibility is poor, minimizing confusion. It's crucial to observe light changes a few seconds in advance while driving—cultivating this good habit helps avoid fines or accidents. Remember, with fixed positions, reactions become quicker.

As a new driver, I found vertical traffic lights a bit unfamiliar at first, but the method taught by my instructor works well: read from top to bottom—red means stop, yellow means slow down, and green means go. The fixed positions eliminate any room for second-guessing. While driving, a quick glance is all it takes. Remember to practice more, and it will gradually become second nature. This approach enhances driving safety and reduces common mistakes made by beginners, such as hesitating at yellow lights or running red lights.

Vertical traffic lights may seem simple, but they must be taken seriously from a safety perspective. The red light at the top signals stop, the yellow light in the middle warns to slow down, and the green light at the bottom indicates go. If not observed carefully or when distracted, misjudgment can easily lead to rear-end collisions or violations. It's crucial to stay focused on traffic signals while driving and make it a habit to double-check before every turn. Ensuring safety for oneself and others is the top priority.

Why are traffic lights arranged vertically with three lights? I think it's for the convenience of drivers to intuitively recognize: the red light, which is the most crucial for stopping, is placed at the top for maximum visibility; the yellow warning light is in the middle as a transitional signal; and the green light for action is at the bottom. This layout efficiently reduces confusion and is especially suitable for urban roads. I think it's a design that helps improve driving smoothness. Following it can save trouble and effort.

On my daily commute, I often encounter this type of traffic light. From experience, I've summarized: read the lights from top to bottom - stop at red, slow down and prepare to brake at yellow, and go when green lights up. The fixed position simplifies decision-making, especially during traffic jams when hesitation is eliminated. Once it becomes a habit, driving becomes smoother and safer. Sharing this practical tip is quite useful—don't overlook it.
