Should You Shift to N or Keep in D at Traffic Lights with an Automatic Transmission?

[LeJuliette]

When waiting at a red light with an automatic transmission, simply hold the brake pedal with your foot and keep the gear in D. Below is an introduction to the gears of an automatic transmission car: 1. P (Park): The parking gear. When the vehicle is completely stationary, press the unlock button at the front of the gear lever to shift into P. 2. R (Reverse): The reverse gear. When the vehicle is completely stationary, press the brake pedal, press the unlock button at the front of the gear lever to shift into R, and after releasing the brake pedal, slowly press the accelerator to move the vehicle backward. 3. N (Neutral): The neutral gear. You can directly shift from R or D into N. To shift out of N, you need to press the brake pedal. 4. D (Drive): The forward gear. You can directly shift from N into D. This gear is generally used when the vehicle is moving forward, and the system will automatically shift up or down based on engine load and vehicle speed.

As a seasoned driver with years of experience driving automatic cars, let me share some insights on gear selection when waiting at traffic lights. Generally, it's best to keep the car in D (Drive) gear while holding the brake, rather than shifting to N (Neutral). Here's why: automatic transmissions are designed to keep the vehicle stable and ready to move when in D gear. If you shift to Neutral, you'll need to press the brake harder, and there's a risk of rolling backward - especially dangerous on rainy days or slopes, making the car more prone to losing control if rear-ended. When stopping in D gear, the drivetrain remains coupled with the engine, consuming minimal fuel without wasting energy, and allows quicker acceleration when you press the gas. I've seen novice drivers mistakenly use Neutral, resulting in their car rolling into flower beds and costing them unnecessary repair bills. Remember, the beauty of automatics lies in their simplicity - just hold the brake at red lights without overcomplicating things. Maintain this driving habit consistently, and you'll have no issues year after year while prolonging your transmission's lifespan.

I usually drive to and from work, and traffic jams at red lights are common. With an automatic transmission car, I always keep it in D gear, firmly pressing the brake to stop steadily. I tried shifting to N gear once, but forgot to brake tightly, and the car rolled back almost causing a scrape—still gives me chills thinking about it. In D gear, the car is in standby mode, not wasting power, and responds instantly when starting, which is especially practical in urban traffic jams. Shifting to N gear disengages the engine, requiring a gear switch to start again, wasting time and increasing the chance of mistakes. During commutes, I only consider shifting to P gear for long red lights, like at railway crossings. Otherwise, keeping it in D gear simplifies operations and is wiser. Here’s a little tip: developing good habits can reduce frustration and improve driving mood—getting home safely is what really matters.

Just learned to drive an automatic car, I'm quite confused about which gear to use at traffic lights. The instructor taught me that it's best to stay in D gear and step on the brake, no need for N gear. N gear is unsafe because the car might roll if the brake is slightly released, and if the car behind is too close, an accident could happen. Parking in D gear is simple and straightforward, and starting is quick—just step on the gas when the light turns green. I tried N gear once and it felt awkward, like something was disconnected, which made me a bit nervous. Now I stick to the D gear method, and it's much more worry-free once you get used to it. Beginners shouldn't overthink it; the whole point of automatic transmission is convenience, don't complicate things for yourself. Just practice controlling the brake with your foot more, safety is the top priority.
