What lights should be turned on when a car exits the highway?

When a car exits the highway, the turn signal should be turned on. Before driving off the highway, the driver needs to activate the car's turn signal and ensure there are no vehicles behind before exiting. The turn signal is an important indicator light that alerts surrounding vehicles and pedestrians when the vehicle is turning. The turn signal uses a xenon lamp tube and is controlled by a single-chip microcomputer circuit, working continuously with alternating left and right flashes. When approaching a general intersection, depending on the road width, traffic flow, and current speed, the turn signal should be activated 10 to 30 meters before the intersection in the direction of the turn. For right turns or lane changes to the right, the right turn signal must be used; for left turns or lane changes to the left, the left turn signal must be used.
I've been driving for many years, often on highways, and I always use my turn signals when preparing to exit. I remember last year, I encountered a novice driver who suddenly changed lanes without signaling, nearly causing a truck behind to rear-end. That experience made me deeply realize that turn signals are not just small gestures—they announce intentions, giving following vehicles time to react and avoid accidents. On highways, speeds are high, and sudden changes without warning can easily lead to chain collisions. I recommend turning on the signal at least 50 meters in advance and checking the rearview mirror to ensure safety. Developing this habit makes driving much safer. Some people skip it for convenience, but details determine safety standards. Starting with ourselves can drive overall environmental improvement.
