After using the turn signal, it generally turns off automatically. Here are some precautions for using turn signals: 1. Turn off the hazard lights before using the turn signal (if the vehicle does not have turn signal priority function). Many car models do not have a turn signal priority function, so if you need to use the turn signal while the hazard lights are on, you should first turn off the hazard lights before activating the turn signal switch. 2. Quickly identify if the turn signal is malfunctioning: Turn signals are divided into contact-type flashers and non-contact-type flashers. When a contact-type turn signal malfunctions, the corresponding turn indicator on the dashboard will stop flashing. When a non-contact-type turn signal malfunctions, the flashing frequency of the corresponding dashboard indicator will increase. Therefore, drivers should pay attention to changes in the flashing frequency of the turn signal indicator while driving. If the above phenomena occur, it indicates that the turn signal is malfunctioning.

Having driven for over 20 years, I know there's an art to whether turn signals turn off or not. When the steering wheel returns to center after a turn, most cars automatically cancel the turn signal - it snaps back like a slingshot. But occasionally during small turns or lane changes, if the steering wheel doesn't turn enough, the signal stubbornly keeps flashing. Once on the highway I forgot to manually cancel it, and the car behind thought I was changing lanes again - we nearly collided. Now it's muscle memory - within two seconds after completing a turn, I always flick the signal stalk with my finger. Extra caution is needed in rain - the loud wiper noise can drown out the turn signal's ticking sound, so I always glance at the dashboard to confirm it's off. Developing this habit saves a lot of trouble.

Last week when I went to the repair shop to change tires, the mechanic casually mentioned something about turn signals. He said that 90% of new cars now come with automatic return springs, and the signals usually turn off by themselves when the steering angle exceeds 45 degrees. But it's hard to say with older cars, especially those over eight years old—the steering mechanism gets sluggish due to wear. Once when I was driving a friend's old , the turn signal kept flashing for half a kilometer after the turn. What's more important is the lane-change operation—the design of lightly tapping the turn signal lever for three flashes inherently requires manual reset. My driving habit is to glance at the rearview mirror after turning, both to check for vehicles behind and to see the reflection of the turn signal in the mirror. After all, getting caught by traffic police for not turning off the turn signal counts as a violation, and the fine could cost you half a tank of gas.

When I was a new driver, my instructor repeatedly emphasized turning off the turn signal. The first time I drove alone to the mall, the signal kept flashing after I turned, causing all the cars on the street to slow down for me—I was so embarrassed I wanted to disappear. Later, I discovered the clever design of the vehicle: turning the steering wheel to full lock triggers a mechanical catch, and with a click, the signal turns off. But in the city, frequent lane changes don’t require such a large steering angle. I figured out a rule: count to three after signaling, and if it hasn’t turned off automatically, manually flip it back. The dashboard also has a reminder—if the green arrow is still lit, it needs attention. Now it’s become second nature; flipping the lever feels as natural as turning the wheel, ensuring safety and saving power.

I've been driving for ride-hailing services for three years, and passengers are most sensitive about turn signal issues. Once, a passenger reminded me that my light was still on, and even after explaining that the auto function had failed, they didn't believe me. In fact, the vehicle manual clearly states: after turning, you need to check the indicator light status. Especially when driving German cars, you need to be extra careful—their turn signal stalks have a lighter return force compared to Japanese cars, making it easier for them not to click into place properly. I've handled several scratch caused by misleading turn signals, all due to not manually turning off the signal after changing lanes. Now, every time I make a turn, I instinctively reach out to feel the stalk position, just like buckling the seatbelt—it's become a conditioned reflex.

When studying automotive circuits, the hazards of continuous operation of turn signals were discovered. Prolonged power supply to relays can cause overheating, reducing bulb lifespan by 30%. More dangerously, it misleads traffic—rear drivers seeing the flashing may assume the front car is turning and suddenly brake, easily causing rear-end collisions. I've tested different models: SUVs have the highest success rate of automatically turning off signals after steering wheel returns to center, while compact cars require manual shutoff after lane changes 70% of the time. Rainy days especially warrant using AC for defogging—only with a clear windshield can dashboard indicator lights be seen properly. Now I've developed a trick: after turning, flick the wiper stalk to simultaneously check the turn signal lever position—double efficiency.
