What is the correct procedure for automatic transmission cars at traffic lights?

If the red light lasts for a relatively long time, such as more than 30 seconds—some urban intersections even have red lights lasting up to 99 seconds—it is generally recommended to shift to N (neutral) gear and then engage the handbrake. This allows the driver to release their foot for a brief rest and is also beneficial for energy conservation and environmental protection. Below are the relevant details: 1. If the traffic light duration is less than 20 seconds, there is no need to shift gears—simply press the brake pedal. If the traffic light lasts more than 20 seconds, it is advisable to shift to neutral and keep the foot on the brake. For durations exceeding 30 seconds, shifting to neutral is also an option, but the handbrake should be engaged. 2. When driving an automatic transmission car and stopping at a traffic light, it is best to avoid shifting to P (park) gear. P gear is intended for long-term parking when the engine is off. Engaging P gear locks the transmission gears, and in the event of a rear-end collision, the transmission could be damaged. Another reason is that P gear is positioned far from D (drive) gear, making switching cumbersome. Therefore, except for parking with the engine off, using P gear is not recommended in other situations.

When driving an automatic transmission car, I pay great attention to safe operations at traffic lights. Typically, I first press the brake pedal to ensure the vehicle comes to a complete stop, then quickly shift the gear to neutral (N position). This helps reduce the burden on the transmission and prevents engine overheating from prolonged idling in Drive (D) mode. Next, I engage the handbrake or electronic parking brake to add an extra layer of protection against rolling. When the light turns green, I immediately shift back to D, release the handbrake, and gently press the accelerator for a smooth start. This routine not only prevents accidental rolling but also protects the drivetrain and extends its lifespan, especially in congested urban driving. Developing this habit enhances overall driving safety. I recommend that beginners practice this procedure more to reduce accident risks.

As a new driver who just got my license, I always feel a bit nervous at traffic lights. My routine is to firmly press the brake to bring the car to a complete stop, then watch the traffic light timer. If the wait is long, I gently shift to neutral. Next, I pull up the handbrake for extra security to prevent any unsettling vehicle movement. When the light turns green, I quickly shift to D, release the handbrake, and start moving—aiming for smooth, decisive actions to avoid hesitation. Though these steps are simple, beginners often forget to shift to neutral and just keep pressing the brake, which might cause slight transmission wear. So, I remind myself every time I stop. With more practice, it becomes natural—the key is to stay calm.

As an experienced driver, my steps at a red light are super simple: brake immediately upon stopping, shift to neutral and engage the handbrake if the wait exceeds ten seconds. At green light, instantly shift to D, release the handbrake, and step on the gas to go. Saves hassle, fuel, and is gentle on the car.

In my daily driving, I pay special attention to environmental protection, so I always shift to neutral when waiting at a red light. This reduces engine load, making combustion more efficient, which saves fuel and reduces emissions. The steps are simple: once you stop by pressing the brake, shift to N, and engage the handbrake to stabilize the car. When the light turns green, shift to D and release the handbrake to start, making the whole process smooth and natural. Consistently doing this not only reduces fuel consumption but also aligns with the concept of low-carbon living, making driving more eco-friendly. Given the frequent traffic lights in cities, I recommend developing this good habit as it benefits the environment.

From my years of driving experience, the correct procedure for automatic transmissions at red lights is highly practical. After stopping by pressing the brake, shift to neutral to prevent transmission damage, and engage the handbrake as a double safeguard; when the light turns green, shift to D, release the handbrake, and accelerate to go. This method is especially suitable when traveling with family, ensuring comfort and safety inside the vehicle. I also take the opportunity to check the dashboard for any abnormalities, making every stop efficient and reassuring.
