How to Use Service Brakes When Parking on a Downhill Slope for Motor Vehicles
2 Answers
Motor vehicles should apply service brakes earlier when on a downhill slope compared to level roads. When driving downhill, the vehicle's speed gradually increases due to gravity, resulting in a longer braking distance than on flat roads. When approaching a downhill section, promptly reduce the vehicle's speed and shift the gear to L (Low) mode. This allows utilizing the engine braking effect to control speed without constant brake pedal pressure, preventing potential brake failure. Using engine braking on downhill slopes is a relatively safer driving practice. For vehicles equipped with a manual-automatic transmission, you can also slow down first when encountering a downhill section, then switch to M (Manual) mode, followed by shifting to a lower gear. The working principle is essentially the same as engaging L mode.
Every time I park on a downhill slope, I'm extra cautious. After driving for so many years, experience tells me this is where cars are most prone to rolling. I first slow down to a complete stop, firmly pressing the brake pedal to confirm the vehicle is stationary. Then I immediately pull up the handbrake and lock it securely in place. For manual transmissions, I'll shift into a low gear like reverse to use engine braking and prevent the car from sliding. On steeper slopes, I also turn the wheels toward the curb - if the handbrake fails, hitting the curb can stop the car. I never want to cause a major accident due to negligence. Once I forgot to engage the handbrake on a steep slope, and the car almost rolled into a ditch - it gave me quite a scare. Now I've developed the habit of testing the brakes after every parking to ensure all systems are functioning properly. Safe driving is no trivial matter; taking those extra preventive steps makes driving much more reassuring.
