Do You Need to Press the Clutch When Decelerating in a Manual Transmission Car?

When decelerating in a manual transmission car, you do not need to press the clutch. The functions of the clutch are: 1. Gradually increasing the driving force of the car to ensure a smooth start; 2. Temporarily separating the engine and the gearbox for gear shifting; 3. Preventing overload in the transmission system; 4. Reducing torsional vibration impacts from the engine and extending the lifespan of the transmission gears. The steps to start a manual transmission car are: 1. Sit in the car properly; 2. Start the car; 3. Press the clutch; 4. Engage first gear; 5. Slowly release the clutch; 6. Gently press the accelerator; 7. Fully release the clutch to complete the car's start. Precautions for starting a manual transmission car: 1. Do not release the clutch too quickly; lift it slowly; 2. Press the accelerator only after the engine and the driveshaft are connected; 3. Gently press the accelerator during the semi-engagement phase, then release the clutch; 4. Release the handbrake before starting.
As someone who has driven manual transmission for years, whether to press the clutch when decelerating depends on the situation. For slight deceleration, such as when traffic ahead slows down, I can gently apply the brakes without pressing the clutch, letting the engine assist in braking, which actually helps protect the brake pads. However, if downshifting is needed, like when going downhill or preparing to accelerate after slowing down, then the clutch must be pressed to shift to a lower gear; otherwise, the car may jerk or even stall. I recommend that beginners practice these scenarios more while learning to drive, as maintaining smooth driving can reduce unnecessary wear and tear on parts, just like controlling speed properly when driving on mountain roads.
I believe that slowing down in a manual transmission doesn't necessarily require pressing the clutch, as it depends on the driving intention. For example, in city traffic jams, I usually just apply the brakes to slow down while keeping the clutch engaged, which ensures smoother power delivery. However, when needing to downshift quickly for sharp turns or obstacle avoidance, pressing the clutch is essential. The safety consideration here is to prevent loss of vehicle control or sudden engine stall. Paying attention to this during daily driving can reduce accidents. During driving lessons, instructors teach us to prioritize road condition assessment—forming good habits is key.
