Should the Clutch Be Depressed When Driving Downhill?

Do not depress the clutch when driving downhill, as doing so is equivalent to coasting in neutral, which is extremely dangerous on a downhill slope. When driving downhill, always engage a low gear to utilize engine braking to help slow the vehicle down. If you encounter a gentle slope on the road, you can control the speed by appropriately applying the brakes without depressing the clutch. However, when navigating continuous curves or very steep downhill sections, it is crucial to promptly shift to a low gear and rely on engine braking to avoid prolonged use of the brakes, which could lead to accidents. Apart from downhill driving, during normal driving, if you need to decelerate, do not press the clutch first. Instead, release the accelerator first, then press the brake pedal without depressing the clutch. As long as the vehicle is moving, the engine will not stall. Only when the vehicle is about to come to a complete stop should you depress both the clutch and brake pedals. In any driving situation requiring deceleration, avoid pressing the clutch pedal first. The clutch pedal should only be used when shifting gears or when the vehicle is about to stop and the engine is to be turned off.
As an ordinary driver who often takes my family on trips, I frequently encounter long downhill slopes. Never press the clutch when going downhill, as this disconnects the engine from the wheels, causing the car to lose control and accelerate uncontrollably, which is highly risky. The safest method is engine braking—shifting to a lower gear to let the engine assist in slowing down. This not only saves brake pads but also maintains stability. Especially on mountain roads, frequent braking can easily lead to overheating and failure, and pressing the clutch in such situations is just asking for trouble. My experience is to slow down in advance and maintain a steady speed when descending, which saves fuel and ensures peace of mind. Remember, safety comes first—don’t cut corners with the wrong maneuvers.
Having driven trucks for over 20 years, my experience tells me that pressing the clutch on downhill slopes is a major taboo. When a manual transmission vehicle is coasting downhill, once the clutch is engaged, engine braking disappears. Relying solely on the brake system for deceleration can easily lead to brake overheating, failure, or even fire. This is especially dangerous on long downhill sections. It's advisable to shift into an appropriate lower gear and use the engine's natural resistance to control speed. This not only protects vehicle components and extends brake life but also prevents unintended coasting. I've noticed many drivers aren't aware of this and frequently press the clutch, resulting in increased fuel consumption and significantly compromised safety. Developing good habits and maintaining stable speed control is the right approach.
