What lights should be turned on in advance when a motor vehicle makes a U-turn?

When making a U-turn, the left turn signal should be activated in advance. Here is relevant information: 1. When there are no streetlights at night: When driving at night without streetlights, with poor lighting, or in low visibility conditions such as fog, rain, snow, dust, or hail, the headlights, position lights, and rear lights should be turned on. However, high beams should not be used when a following vehicle is driving close to the vehicle in front in the same direction. In foggy conditions, fog lights and hazard warning flashers should be activated. 2. When there is no traffic signal control: When driving through sharp curves, slopes, arched bridges, pedestrian crossings, or intersections without traffic signal control at night, the driver should alternately switch between high and low beams to signal. 3. When turning left or preparing to overtake: The left turn signal should be activated in advance when turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn.

Having driven for decades, I believe the key to making a U-turn is to activate the left turn signal in advance, which clearly communicates your turning intention and prevents misjudgment by vehicles behind or pedestrians. Especially at large intersections, failing to signal can easily lead to rear-end collisions or honking. I remember a rainy day a few years ago when I didn't turn on the signal in time while making a U-turn and was almost hit by a truck. Since then, I've always activated the left turn signal three seconds early, glancing at the rearview mirror to confirm safety before turning. Developing this habit isn't just about following rules—it's life wisdom. Signaling makes driving easier and more reassuring.

I haven't been driving for many years, but last month I forgot to turn on the turn signal when making a U-turn, and it wasn't until a friend reminded me that I learned to use the left turn signal. Turning it on in advance is like saying 'Hey, I'm about to turn,' so others naturally slow down or go around. As a beginner, I thought it was unnecessary, but after practicing, it really helps reduce misunderstandings. For example, when turning in the neighborhood with the signal on, cyclists give way more smoothly. Now I also make it a habit to check the side blind spots more carefully when making a U-turn. Combining signaling with caution can protect both myself and those around me. Remember to turn on the signal at least five seconds before starting the U-turn maneuver.

Emphasizing safe driving, turning on the left turn signal when making a U-turn is a fundamental action. This signal clearly communicates your intention, reducing the risk of sudden turns causing accidents. I always remind myself to activate it early, giving vehicles behind me time to react. Although the rule is simple, it's especially important on highways or at night. At the same time, observe the road conditions to ensure no one is approaching before starting the U-turn. Safety comes first, and developing the habit of using turn signals makes travel more controllable and reassuring.
