Why Do Experienced Drivers Engage First Gear When Parking on a Slope?

[RachelMarie]

Because when parking a manual transmission car on a slope, engaging reverse gear on a downhill and first gear on an uphill utilizes the engine's resistance to help the vehicle better utilize the parking brake effect. Since first gear and reverse gear are the two gears with the largest transmission ratios in the car's transmission, and also the two gears with the smallest transmission ratios during power reverse transmission, using first gear and reverse gear to engage the engine's parking brake provides the maximum braking force and the best braking effect. Extended content, gear shifting tips: 1. Remember the principle of "accelerate before upshifting, decelerate before downshifting" when changing gears. Before upshifting, "rev" the throttle to increase the speed first, and before downshifting, "release" the throttle to reduce the speed first. 2. When shifting gears, try to use the "double-clutching method". When upshifting, follow the principle of "press (clutch), shift (neutral), press (clutch), engage (higher gear)", quickly press the clutch pedal twice, which can easily increase the gear.
