How to Turn On the Left and Right Turn Signals?

[Cupid]

First, nowadays, the turn signal switch in cars is generally installed on the left side of the steering wheel. The operation method can be summarized as "up for right, down for left," so saying "up for left, down for right" is incorrect. Drivers can imagine the turn signal lever as the steering wheel—turn it in the direction they intend to go. The "up for right, down for left" method aligns with general habits: pushing down (counterclockwise) is commonly understood as turning left, while pushing up (clockwise) is interpreted as turning right. The steps to activate the turn signals are as follows: 1. If you observe a need to turn while driving, be sure to activate the turn signal about 10 seconds in advance to alert vehicles behind you, allowing them time to take appropriate actions, such as slowing down or stopping, to avoid collisions or even rear-end accidents. However, it's also best not to activate the turn signal too far in advance, as this might cause visual fatigue for drivers behind you, potentially leading to "road rage." The timing should be carefully judged by the driver. 2. As a signal light, the turn signal's primary role during daily driving is to inform surrounding vehicles of your intended direction change, prompting them to yield and avoid collisions. Therefore, whether turning, changing lanes, overtaking, starting, or parking, whenever the vehicle's wheels deviate from the original lane, the turn signal should be activated in advance. This is a fundamental principle of safe driving. In daily driving, drivers often overlook using turn signals in situations such as entering roundabouts, merging from ramps onto highways, or in parking lots—scenarios where accidents due to neglected turn signals frequently occur.
