How to Understand Traffic Signals?

[BrooklynAnn]

Green means go, red means stop, and yellow warns of an impending signal change. Here is an introduction to traffic signals: 1. Green Signal The green signal indicates permission to proceed. According to the "Regulations for the Implementation of the Road Traffic Safety Law," when the green light is on, vehicles and pedestrians are allowed to proceed, but turning vehicles must not obstruct the passage of straight-moving vehicles and pedestrians. 2. Yellow Signal When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. The yellow signal's meaning lies between the green and red signals, having both a prohibition and a permission aspect. When the yellow light is on, it warns drivers and pedestrians that the passage time is ending and will soon switch to red. Vehicles should stop behind the stop line, and pedestrians should not enter the crosswalk. 3. Red Signal Stop driving.

When I first got my driver's license, I was always confused by the round traffic lights. Later, I realized that understanding traffic signals starts with identifying their types. The basic round lights follow the ironclad rule: stop at red, go at green, and don't rush at yellow. Arrow lights are more precise—you can only turn or make a U-turn when the green arrow is lit. Countdown timers are the most user-friendly, allowing you to anticipate how many seconds are left to cross the intersection. At night, flashing yellow lights require extra vigilance, as they signal you to observe road conditions carefully. Nowadays, cities also have signal poles with pedestrian icons and crosswalk buttons—don’t just focus on the vehicle traffic lights when crossing the street. In real driving situations, if a large truck ahead blocks your view of the signal, don’t blindly follow it through; it’s safer to wait for the next light cycle instead.

After riding an electric bike for five years, I finally realized that watching traffic lights isn't just about the colors. The small details on the light poles are particularly important: if there's a green light but it says 'Proceed in the direction of the arrow,' you need to pay attention to the turning rules; lights with dynamic arrows require you to anticipate whether they might turn red. Last time in the new district, I encountered a three-row combination light—the top row was for left turns, the middle for straight, and the bottom for right turns—and I almost turned into the wrong lane. On rainy or foggy days, remember to get closer to the lights to see clearly, as reflective road surfaces can make the lights appear blurry. Now, when approaching an intersection, I've developed the habit of first checking the light group corresponding to my lane and then scanning the pedestrian crossing lights, because pedestrians suddenly darting out is the most dangerous situation.

The instructor taught me three things to remember when identifying traffic lights: color, position, and sequence. The red light is always at the top, the yellow light in the middle, and the green light at the bottom. At intersections, the most feared mistake is misidentifying lane lights—a straight lane might have a turn signal. Ignore the bus-only lights marked with a 'B'; private cars only need to watch the regular light set. In special sections like tunnel entrances, the red cross and green arrow lights indicate that a red cross means the road ahead is blocked and you need to change lanes. When crossing the street with children, I teach them to remember the light language—red means stop, green means go, and a flashing green person means the light is about to turn red, so hurry up.

The voice-prompted traffic lights at our school gate are the most practical, but for regular traffic lights, focus on three key points: light type determines right of way, circular lights allow passage in all directions, while arrow lights only permit movement in the specified direction. Can you turn right on red? It depends on whether there are no-turn-on-red signs or arrow lights. If the rear wheels have crossed the line when the yellow light comes on, you can proceed; if the front wheels haven't crossed, you must stop. The most troublesome situations are when tree shade or strong sunlight obscures the traffic lights—in such cases, slow down and observe the movements of nearby vehicles or refer to pedestrian signals. Remember, if a bus remains stationary, it's most likely a red light; this simple trick has saved me twice.

When driving at night, be vigilant about malfunctioning traffic lights. Last year during a heavy rainstorm, I encountered a situation where all the lights at an intersection were out. In such cases, treat it as an unregulated intersection, and the 'yield to the right' rule is far more reliable than seeing who's braver. Nowadays, newly installed smart traffic lights can change modes—during morning rush hours, the straight-through green light lasts longer, while during off-peak periods, they switch to simultaneous left and right turns. When driving in an unfamiliar city, pay attention to the supplementary instructions on road markings and overhead signs. At some intersections, right turns on red are allowed but you must yield to pedestrians. I make it a habit to ease off the accelerator about 200 meters before reaching an intersection, which saves fuel and allows me to clearly see any changes in the traffic lights.
