What does it mean to park in 2nd gear?
2 Answers
When parking on an uphill slope with the front of the car facing upward, it is best to leave the car in 1st or 2nd gear and then engage the handbrake. This provides additional safety to prevent the car from rolling backward in case the handbrake fails. Below is a detailed introduction to car gears: 1. Manual transmission: Generally consists of 5 forward gears + 1 reverse gear. More gears usually allow for more flexible speed control and better utilization of the car's power, which also makes it more fuel-efficient. 2. Automatic transmission: Typically, the gear positions are marked with P, R, N, D, 1, 2, 3, etc. P stands for parking gear, N for neutral, D for the normal forward driving gear, and 1, 2, 3 are also forward gears, but the higher the number, the greater the torque. 3. Continuously Variable Transmission (CVT): Very similar to automatic transmission, but unlike automatic transmission which is electronically controlled, it is actually a mechanical automatic transmission.
When I was learning to drive, my instructor specifically corrected this habit. Parking in 2nd gear is actually a misconception. For manual transmission cars, engaging any gear after turning off the engine can provide some anti-roll effect, but the gear ratio of 2nd gear is too small, making it far less effective than 1st gear or reverse gear. Moreover, parking with the gear engaged while the engine is off can lock the transmission, and forgetting to disengage the gear when restarting may cause the car to lurch, damaging the starter motor and flywheel ring gear. More dangerously, if the brakes fail on a slope, the braking effect of 2nd gear is simply insufficient. The correct practice is to pull the handbrake firmly and shift to neutral. Only when parked on a steep slope should you engage reverse or 1st gear for added security. I once tried parking in 2nd gear and almost hit a wall, so I never dare to do it again.
