Turn signals generally require manual deactivation. After engaging the turn signal, when the steering wheel returns to the central position, you'll hear a faint "click" sound indicating reset. However, if the steering angle during lane changes is too slight, the signal won't automatically reset. Below are relevant explanations: 1. Function of turn signals: As the most frequently used lighting feature, turn signals clearly communicate intended driving directions to surrounding vehicles. Yet many drivers neglect proper turn signal usage during operation, with some even unaware of appropriate usage scenarios, creating significant safety hazards. Therefore, understanding proper turn signal application is essential. 2. Timing for activation: Turn signals primarily notify trailing vehicles of intended turns, prompting caution. Drivers should activate signals 10-20 seconds before turning to provide adequate reaction time. 3. Activation verification: Determining whether turn signals are engaged is straightforward - simply check the instrument panel for the corresponding indicator light (as shown in the diagram above). These indicators display turn signal positioning, normally remaining off. When activated, the directional indicator illuminates accordingly and extinguishes automatically upon signal deactivation.

After driving for so many years, I've noticed that the turn signals usually turn off automatically after a turn, thanks to the steering wheel's linkage reset mechanism. When you straighten the wheel, it triggers an internal mechanism to cancel the turn signal. However, if the steering wheel isn't fully straightened or the turn is too slight, the signal might stay on, requiring you to manually press the button to turn it off. This is quite common, especially at small intersections or U-turns. Forgetting to turn it off could lead to misunderstandings from following drivers, who might think you're still turning or changing lanes, increasing the risk of a rear-end collision. I recommend getting into the habit of slightly straightening the wheel after each turn and double-checking. If it occasionally fails, it might be due to system wear, and a visit to the repair shop would be advisable.

As a frequent driver, I've noticed that whether turn signals automatically turn off mainly depends on the age of the car. Most modern vehicles have this feature—the lights go off when the steering wheel returns to center. However, older or economy cars might not, requiring manual lever operation to turn them off. I've driven a friend's car where it sometimes malfunctioned because the internal return spring had aged and loosened. If left on for too long, besides being a safety hazard, it drains the battery and can even burn out the bulb. Always stay alert while driving, especially checking after turns. If issues persist, don't delay repairs.

From a safety perspective, automatic turn signal cancellation is crucial. Most vehicles automatically turn off the indicators after the steering wheel returns to center position, preventing misleading other drivers or causing accidents; if left on, they might be mistaken as an intention to change lanes, increasing collision risks. I always verify the signals are off after completing a turn to ensure driving safety. Prompt inspection is necessary when occasional malfunctions occur.
