If it's an automatic transmission car, then this operation is possible. If it's a manual transmission car, this operation will directly cause the engine to stall. Operation Explanation: Cars equipped with automatic transmissions will automatically downshift when braking, and the downshift speed of an automatic transmission is faster than that of a manual transmission, so you can directly press the brake to stop. Gear Shifting: The general gear shifting timing for most cars is when the engine speed is at 2000r/min, preferably not exceeding 2500r/min. For some high-displacement, high-power engines, the maximum efficiency range is often delayed a bit, so you might consider shifting gears around 3000r/min.

Having driven manual transmission cars for over a decade, I strongly advise against leaving your car parked in 3rd gear. This practice can easily cause stalling or starting difficulties, especially on slopes which is particularly hazardous. The proper parking procedure should be: brake to a complete stop, shift to neutral, engage the handbrake to secure the vehicle, and only then turn off the engine. Parking directly in 3rd gear locks the gears in place, forcing the engine to bear load continuously. Over time, this can damage the transmission or starter motor, leading to costly repairs. From a safety perspective, developing good habits is crucial. I always shift to neutral when parking to prevent sudden rolling or potential accidents. During long drives, paying attention to this small detail can prevent many troubles and ensure safety for both yourself and other drivers – safety always comes first.

As a car enthusiast, from a mechanical perspective, stopping in 3rd gear is definitely not acceptable. In a manual transmission, when the gears are engaged, if you stop directly, the clutch pressure plate and gears are still connected, and the engine isn't completely disengaged. The starting moment would have to withstand the torque directly, which could easily stall the engine and potentially damage the engine shaft. The correct parking procedure is: when the vehicle speed is zero, press the clutch, shift to neutral, engage the handbrake, then release the foot brake and turn off the engine. Think about it, gears are designed to bear force during operation. Keeping them engaged while stationary after parking could accelerate gear wear. Saving those steps might actually increase future repair costs. I think it's good to learn more about car structures, like how the drivetrain works, to help avoid such basic mistakes.

Once I was in a hurry while driving and forgot to shift gears before turning off the engine—it was left in 3rd gear. The next day, the engine struggled to start, and I ended up calling a tow truck, which was a huge hassle. The lesson learned is not to skip steps: always brake to a complete stop, shift to neutral, and engage the handbrake when parking. The gear bears the load while the car is running, and failing to shift properly when stopping can cause issues with the clutch and starter motor. The car manual emphasizes this—it’s just a simple habit to develop. In daily driving, such small mistakes may be rare but costly. Now, I always check the gear position to ensure safety and peace of mind.
