What are the functions of turn signals?

Turn signals can alert pedestrians and other vehicles that the car is about to turn or change lanes. They serve to inform pedestrians and other vehicles of the current vehicle's intention to turn. When both left and right turn signals flash simultaneously, it indicates an emergency situation, alerting other vehicles to be cautious. The light of turn signals is yellow. It is essential to use turn signals when starting the vehicle, changing lanes, or making turns. Information about turn signals is as follows: 1. The turn signal bulb uses a xenon tube, controlled by a single-chip microcomputer circuit, with left and right alternating flashes working continuously. 2. Turn signals use a flasher to achieve the blinking effect. The timing for turning them on should be well managed; they should be activated about 100 meters before the turn. If changing lanes, they should be turned on even earlier.
I've been driving for twenty years, and the most crucial function of turn signals is to inform others which way you're turning or changing lanes. This allows others to slow down in advance to avoid collisions. During rush hour traffic in the city, suddenly changing lanes without signaling can easily lead to accidents—I've witnessed several near-miss rear-end collisions. Another important role they play is serving as hazard warning signals when your car breaks down or is involved in an accident, protecting both yourself and others. Some older cars have turn signal bulbs that tend to burn out easily, so I recommend regularly checking the wiring—for example, looking for oxidation or rust at contact points. In cold or foggy weather, keeping the lights flashing increases visibility and prevents accidents caused by poor visibility. Safe driving isn't complete without this small but vital component—making it a habitual practice can be a lifesaver.
