How to Activate the Left Turn Signal in a Car?

[DaisyRose]

To activate the left turn signal in a car, simply push the turn signal lever downward. The functions of turn signals include: 1. Indicating the intended turning direction to pedestrians or other vehicles; 2. Signaling the direction for overtaking or lane changing; 3. When both left and right turn signals flash simultaneously, it indicates an emergency situation to alert other vehicles. Precautions for using turn signals are: 1. Activate the turn signal in advance before turning; 2. Use the left turn signal when overtaking and the right turn signal when returning to the original lane; 3. After activating the turn signal, observe pedestrians and oncoming vehicles before maneuvering; 4. Before making a left turn or U-turn, check for any road signs prohibiting such actions before activating the turn signal.

When I first started driving, I was most afraid of using the wrong turn signal. Later, I found that the basic rule is quite simple: the lever on the left side of the steering wheel—pushing it down activates the left turn signal. Remember the phrase ‘down for left,’ which applies to 90% of cars. In practice, you should activate it about 100 meters in advance. When you hear the clicking sound, it means the signal is on. The key is to push it all the way—some cars have a half-press and full-press distinction: a half-press flashes three times and stops automatically, suitable for lane changes; a full-press requires manual resetting. Remember to turn off the signal after completing the turn, especially with older mechanical levers that can get stuck. Checking the arrow indicator on the dashboard is the safest bet. Recently, I’ve noticed that with touchscreen-operated cars like Tesla, it’s even more important to familiarize yourself with the interface layout in advance.

Last time when teaching my cousin to drive, I emphasized that there's actually a trick to operating the turn signal: use three fingers of the left hand to hook and pull the stalk downward, so your view doesn't need to leave the road. What driving schools don't teach is to especially check the lighting effect during rainy or foggy weather—I once discovered my left turn signal had poor contact only when making a turn in the rain. The feedback force varies between different car models too; German cars have a crisp click sound from the stalk, while Japanese cars are more gentle. Another situation is that new drivers often mistake the wiper for the turn signal, so it's recommended to test the signals after a cold start before setting off. If the steering wheel has been modified, it's even more important to confirm the stalk position isn't obstructed. Regularly cleaning the stalk contacts can prevent poor contact issues.
