The correct use of car turn signals is a crucial part of safe driving. While the operation method varies by vehicle model, the principle is the same. Electronic button-type turn signals are mostly found in high-end models, controlled via touch screens or physical buttons. When using turn signals, they should be activated 3 seconds in advance. Before changing lanes, check the rearview mirror to confirm safety. When overtaking, first use the left turn signal to indicate intent, and after completing the overtaking, use the right turn signal to return to the original lane. When exiting a roundabout, the right turn signal should be activated in advance, while no signal is needed when entering. When driving at night or in rainy weather, It is best to extend the signal activation time to 10 seconds, and regularly check for water accumulation in the lamp housing and whether the bulb brightness is normal. Special attention should be paid to immediate maintenance if the turn signal flashes abnormally, and original manufacturer-specified parts should be used when replacing bulbs. Standardized use of turn signals not only prevents rear-end collisions caused by sudden lane changes but also demonstrates the most basic courtesy to other road users. It is recommended that new drivers master the operational essentials for different scenarios through simulation training and develop the habit of observing before acting after activating the turn signal.
