What lights to use when passing through an intersection ahead?

[Young]

There are several situations for using lights when passing through an intersection ahead: 1. Going straight: If going straight through an intersection with traffic lights ahead, use low beams directly. If passing through an intersection without traffic lights, alternate between high and low beams more than twice, slow down in advance, and signal by alternating between high and low beams while paying close attention to the traffic conditions ahead. 2. When overtaking: When overtaking at night, turn on the turn signal in advance and observe the vehicles behind. If the following vehicle is too close, it is not recommended to overtake with the turn signal on, as this may easily catch the following vehicle off guard. 3. When changing lanes: To prevent the vehicle ahead from changing lanes while overtaking, try to remind the other party by honking or quickly switching between high and low beams to alert the vehicle ahead. Observe it at this time. If there is no intention to change lanes, you can accelerate to overtake; if the vehicle ahead turns on the left turn signal, it indicates an emergency situation ahead and is not a good time to overtake, as it also needs to change lanes.

I've been driving for over a decade and am most familiar with signaling at intersections. For going straight, you generally don't need to signal, but for turns, you must use your turn signals in advance: left turn signal for left turns and right turn signal for right turns. Timing is also crucial—I usually turn on my signal 30 to 50 meters before the intersection so vehicles behind can clearly understand my intention. Especially at large intersections or at night when lights can be blurry and accidents more likely, signaling early helps prevent misunderstandings. Some people signal the wrong way or forget to signal—I made those mistakes myself when I first started driving, but it became second nature with practice. Signaling is even more critical in heavy traffic at intersections; it helps everyone coordinate and avoid accidents. In rainy or foggy conditions, avoid randomly using hazard lights—stick to normal lighting for safety. In short, the rules are simple but the details matter, and practice makes perfect.

I just got my driver's license and I'm still quite nervous. My instructor taught me the rules for intersections: use your turn signals when turning—left turn means left signal, right turn means right signal. For going straight, you usually don’t signal, but you should slow down and observe the traffic lights. During my last test, I almost failed because I didn’t signal in time, so now I remember to activate the signals dozens of meters in advance. Confusing signals at intersections are common, so always check road signs and pedestrian flow to avoid mistakes. Using signals isn’t just for passing the test—it helps prevent rear-end collisions and keeps everyone safe. A simple tip from my driving lessons: keep your eyes on the intersection changes and don’t stop moving your hands. With more practice, you’ll gain confidence gradually.

From a professional perspective, the rules for using lights at intersections are very clear. When turning, you must use the turn signal to indicate your direction, allowing other road users to anticipate your actions; when going straight, no signal is needed, but maintaining steady lighting is crucial. It is recommended to activate the turn signal about 50 meters before the intersection to ensure clear communication. Traffic laws emphasize that this can significantly reduce accident rates, especially in chaotic intersection scenarios during peak hours. In rain or snow, avoid randomly using hazard lights and stick to normal lighting to prevent misinterpretation. The improvement in safety is notable, and I recommend regularly checking your vehicle's lights to minimize malfunctions.

I always drive cautiously, with intersection safety being the top priority. The turn signal rules are simple: activate the corresponding turn signal when turning, generally not when going straight, but full attention is a must. Using signals gives pedestrians and vehicles reaction time, reducing collision risks. At dimly lit intersections, I take extra care and signal early to indicate my intentions. In high-traffic areas like school zones, consistent signaling helps foster a safer environment. Remember to adjust speed in sync with signaling to avoid sudden braking. Maintaining smoothness throughout the driving process, with signals being a key component.
