Should You Press the Brake When Shifting Gears in an Automatic Transmission?

Whether you need to press the brake when shifting gears depends on the specific situation. Here’s a detailed explanation: 1. Shifting from P to other gears requires pressing the brake: The P gear is the parking gear, where the locking mechanism engages the transmission to prevent it from rotating normally, serving as a rigid locking function. This is designed to prevent the vehicle from rolling away if parked on an uneven surface. Manufacturers considered that if, on a slope, the driver doesn’t engage the handbrake and can shift out of P without pressing the brake, the vehicle could immediately roll backward, leading to potentially disastrous consequences. To avoid this, the P gear is equipped with a solenoid locking function that requires pressing the brake to release. 2. Shifting from N to D or R requires pressing the brake: The N gear is the neutral gear. The engine's power is directly transmitted to the transmission. If the car can start without pressing the brake, the vehicle would move forward or backward as soon as the driver shifts into D or R. In case of an operational error, it would be difficult to react quickly by braking, posing a risk of accidents.
When I first started learning to drive, I was quite nervous the first time I drove an automatic car. I didn’t know you had to press the brake to shift gears, so when I moved from Park (P) to Drive (D), the car didn’t move, which was really awkward. Later, a friend told me that you must press the brake to shift gears—it’s a safety measure to prevent the car from rolling or accidentally starting. Since then, I’ve developed the habit of always pressing the brake when shifting, whether from P to D or when reversing into R, especially at traffic lights or when starting on a slope, as failing to do so could cause the car to stall or pose a safety risk. While some high-end cars may not require pressing the brake to shift into Neutral (N) on flat ground, I’d advise beginners to stick to this step to avoid accidents. After driving for a while, it becomes as instinctive and simple as a safety reflex.
As a veteran driver with nearly two decades of experience driving automatic transmission vehicles, I can confidently say that stepping on the brake is mandatory when shifting gears, especially when engaging drive mode D or reverse gear R. This is a fundamental operating procedure - without pressing the brake, the gearshift lever will remain locked and unresponsive, or trigger warning sounds in some vehicle models. I've developed the habit of always braking during gear changes when starting up or stopping, whether parallel parking on crowded streets or taking breaks at highway rest areas, as it effectively prevents vehicle creep. Moreover, cultivating this practice helps reduce transmission wear - for instance, applying brakes before gear shifts on slopes prevents rollback collisions. My experience proves these techniques make driving significantly smoother and safer.
