How to Interpret the Three Stacked Traffic Lights?

The left light corresponds to left turns, the middle light to straight-through traffic, and the right light to right turns. When proceeding, you may cross the intersection when the light corresponding to your intended direction of travel displays green. Directions displaying red indicate prohibited movement.

After driving for so many years, I've gotten used to handling the top, middle, and bottom traffic lights. The top light usually indicates a left turn, the middle green light means you can go straight when it's on, and the bottom light is dedicated to right turns. I remember once during rush hour in the city, the traffic at the intersection was particularly heavy. I kept my eyes on the middle light and waited for it to turn green before moving, which helped me avoid a rear-end collision. If the top light turns on, I prepare to turn left, and if the bottom light comes on, I turn right. On rainy or foggy days when the lights might not be very clear, I always slow down and roll down the window to confirm, making sure not to confuse the positions of the lights. When I was a beginner, I often got confused, but after driving a few more times, I memorized the meaning of each light and developed the habit of observing and judging more. At intersections, don't rush; be patient and wait a few seconds when the lights change—safety is much more important than time. In short, remember that top, middle, and bottom correspond to left, straight, and right, and driving will become much smoother.

From a safety perspective, the top, middle, and bottom traffic lights must never be taken lightly. The top light controls left turns, the middle one is for going straight, and the bottom indicates right turns. I have learned this the hard way—once, I almost ran a red light because I didn’t clearly see the top light, nearly causing a collision. Whether it’s day or night, only move when the light turns green, and come to a complete stop when it’s red. Especially in bad weather, like heavy rain when the lights appear blurry, I pull over slightly to let my eyes adjust and turn on the defroster to aid visibility. Following traffic light rules helps prevent accidents, particularly at busy intersections with heavy traffic. If a light is broken or flickering unpredictably, it’s best to call traffic control for confirmation. Develop good habits and prioritize paying attention to light changes. The core of safe driving is respecting these signals—never act on your own assumptions.

When I first started learning to drive, my instructor taught me to observe the top, middle, and bottom traffic lights. When the top one lights up, you can turn left; the middle green light means you can go straight, and when the bottom one lights up, get ready to turn right. I was quite confused back then, fumbling at intersections and always afraid of mixing up the light positions. Through several practice sessions, I gradually adapted during simulated driving—for example, slowing down and glancing before the light turned green. This part was heavily tested during the driving license exam, so I forced myself to memorize the left-middle-right correspondence. Now, it feels natural when driving, and I recommend other beginners to practice their observation skills using in-car videos more often. It’s actually not that complicated—just simple correspondence to get started.

Regarding traffic light rules, I've observed at various intersections that the top light is generally designed for left-turn signals, the middle light indicates straight movement, and the bottom light controls right turns. When the top light turns green, I make a left turn; when the middle light is on, I proceed straight; and when the bottom light flashes, I prepare to turn right. It's important to note that these lights differ from vertical ones as they are horizontally arranged for different turning directions. The color rules must be strictly followed: stop at red, go at green, and yellow serves as a warning. In specially designed areas like smart intersections, the lights are coordinated to prevent confusion. I've reviewed official guidelines emphasizing that ensuring each light is clearly visible is a driver's responsibility. Remembering their positions makes everything effortless.

Here are some tips for dealing with the top, middle, and bottom traffic lights while driving. The top light is for left turns, the middle light indicates when to go straight, and the bottom one is dedicated to right turns. I usually pay close attention to the light changes and avoid rushing during peak hours—wait until the light stabilizes before moving, such as proceeding forward only when the middle light turns green. At night, I turn on the car's low beams to better see the position of the lights and avoid mistakes due to poor visibility. Additionally, in rainy or foggy conditions when the lights can appear blurry, I make sure to clean the windshield for a clearer view. Regular car maintenance also helps prevent misjudgments. Overall, the key advice is to practice more and stay observant—just match left, middle, and right accordingly.
