How to Shift Gears at a Red Light in an Automatic Transmission Car?
2 Answers
When waiting at a red light in an automatic transmission car, the appropriate gear to shift into depends on the duration of the red light. The shifting recommendations are as follows: 1. If the red light is less than 30 seconds, it is recommended that the driver simply keep their foot on the brake. 2. If the red light lasts between 30 seconds and 1 minute, the driver should shift into N (Neutral) gear and engage the handbrake. 3. For red lights longer than 1 minute, it is advisable to shift into P (Park) gear and engage the handbrake. Below are some general driving tips for automatic transmission cars: 1. Shifting gears at a red light: For short red lights, it is recommended to shift into P or N gear for lower fuel consumption; on a slope, shifting into P gear is advisable; on flat roads, remember to engage the handbrake when in N gear to prevent accidents. 2. Starting the car in P gear: When starting the car, shifting from P to D gear passes through R (Reverse) gear, which can cause a reverse impact on the transmission, potentially damaging it over time and harming the vehicle.
I've been driving automatic transmission cars for many years. When encountering a red light, I usually keep it in D gear and press the brake pedal while waiting for the green light. This is the safest practice because it allows immediate acceleration, avoiding rolling back or delayed response accidents. If the red light is short, within 20 seconds, just keep pressing the brake; but if there's prolonged traffic congestion or the red light lasts over a minute, I shift to N gear and engage the handbrake. This gives the engine and transmission a rest, reducing unnecessary wear and fuel consumption. Remember not to shift to P gear - if rear-ended, it might damage the transmission. Developing good habits is crucial to ensure driving safety. Don't take risks just to save a little time.
