How to Prevent Rolling Back When Driving an Automatic Transmission Car on a Slope?

[VioletFitz]

There are three methods to prevent rolling back when driving an automatic transmission car on a slope: 1. Use your left foot to press the brake pedal while stepping on the accelerator with your right foot. Increase the RPM to above 3000, then release the brake with your left foot. However, since the foot brake applies braking force to all four wheels simultaneously, locking the drive wheels while stepping on the accelerator may theoretically damage the transmission gears. 2. Engage the handbrake, release the foot brake, and step on the accelerator. Once the RPM reaches a certain level, release the handbrake to start moving. This method is similar to the principle of starting a manual transmission car on a slope. Since the handbrake locks the rear wheels, it won’t damage the transmission. 3. "Hovering": Before approaching the toll booth, completely release the accelerator without pressing the brake. When the car's forward momentum completely disappears, gently press the accelerator. At this point, the gravitational pull and the engine’s power reach a balanced state, allowing the car to stop completely on the slope without using the brake or handbrake.
