Should an automatic car be shifted to neutral when waiting at a traffic light?

[EmmettLynn]

When waiting at a traffic light in an automatic car, it is safer to shift to neutral and engage the handbrake. Below are detailed introductions to the car gears: P gear is the parking gear: When the gear lever is in the P position, the transmission is in neutral inside, but the output shaft is mechanically locked. At this time, the car will stop in place even without stepping on the brake. It is generally used when the car is parked for a long time. When shifting into P gear, the car must be completely stationary. Do not shift into P gear when the car is not fully stopped, and always engage the handbrake. When parking on a slope, you need to engage the handbrake first before shifting into P gear. R gear is the reverse gear: When the gear lever is in the R position, the rotation direction of the transmission output shaft is opposite to that of the engine, allowing the car to move backward. When shifting into R gear, the car must be completely stationary. Do not shift into R gear when the car is not fully stopped. N gear is the neutral gear: When the gear lever is in the N position, the gears inside the transmission are idling, and the clutch is not engaged. The load on the transmission is minimal at this time. N gear is generally used for short-term parking. In addition, when towing the car, the transmission should also be shifted into N gear. D gear is the driving gear: When the gear lever is in the D position, the gears inside the transmission automatically switch between the lowest and highest gears according to factors such as vehicle speed and throttle opening, based on the preset shifting pattern. In most cases, you can drive using D gear.

To be honest, after driving for so many years, I think whether to shift to neutral at traffic lights depends on the situation. For short waits of just a dozen seconds, keeping it in Drive is fine—it allows you to move as soon as the light turns green, avoiding the hassle of shifting back and forth. But if the traffic jam lasts longer, say over a minute, I shift to neutral or Park to prevent the transmission from overheating and affecting its lifespan. Don’t forget, frequent gear changes can also cause unnecessary wear. Overall, developing good habits protects your car—don’t underestimate these small details.

As a commuting driver, I believe it's usually unnecessary to shift to neutral at red lights. Automatic transmissions are designed with idle waiting in mind, and staying in Drive allows for quicker starts without significantly increasing fuel consumption. Of course, if you're a beginner or concerned about vehicle wear, you can shift to neutral during long red lights for a break, but make sure the handbrake is firmly engaged. Remember, safety first - don't get distracted by your phone while shifting gears. Overall, just adjust according to the duration of the red light.

Hey, shifting to neutral at red lights while driving is a matter of habit. I often hear people say it saves fuel, but the difference is actually minimal. For short stops, keeping it in Drive is fine—the transmission isn't that fragile. If the red light is long, shift to neutral to avoid heat buildup. Developing this habit is better for the car.

Having been in the auto repair industry for a long time, I recommend not shifting to neutral at red lights for automatic transmissions. Unless it's an exceptionally long wait, staying in Drive is more stable and reduces unnecessary stress on the transmission. Shifting to neutral can increase fuel consumption risks, especially in urban traffic. Pay extra attention to vehicle dynamics when waiting at lights.

When driving, I always consider the environmental impact. Should I shift to neutral at red lights? For short stops, staying in Drive is fine, as reducing gear shifts can save some fuel. However, if the red light lasts more than 30 seconds, switching to neutral can reduce fuel consumption and emissions. Remember to balance safety.
