What is the minimum speed for second gear?

[LaneDella]

The speed in second gear should not be lower than 10 km/h. A manual transmission car uses a manual shift mechanical transmission (also called manual transmission, MT) to adjust the vehicle speed. This means you need to manually move the gear lever to change the gear engagement position inside the transmission, altering the gear ratio to achieve speed variation. The gear-speed matching requirements during the driving test (Subject 3) are as follows: first gear allows 0-20 km/h, shift to second gear at 15-20 km/h; second gear allows 10-30 km/h, shift to third gear at 25-30 km/h; third gear allows 20-40 km/h, shift to fourth gear at 35-40 km/h; fourth gear allows 30-50 km/h, shift to fifth gear at 45-50 km/h.

When I first started driving a manual transmission car, I learned that you shouldn't go too slow in second gear, otherwise the engine tends to shake or even stall. Generally, the speed shouldn't drop below 10 to 15 kilometers per hour. My car is a compact model, and if the speed falls below 10 km/h, you can already feel the shaking, but if it drops to 5 km/h, it really won't work. This is related to the car's torque—small-displacement cars are more sensitive, and at low RPMs, the power can't keep up, putting more strain on the engine. When driving in the city, I usually stay in second gear above 15 km/h; if it drops below that, I shift back to first gear for smoother driving to avoid frequent stalling. On the highway, it's less of a concern, but it's especially important when turning or climbing hills—not downshifting can lead to higher fuel consumption and shorten the lifespan of components. After driving a few different brands, you'll get a feel for each car's quirks.

When learning manual transmission, the instructor emphasized not to let the speed drop below 12 km/h in second gear. Once, I slowed down to 8 km/h going down a slope in my neighborhood, and the car seemed to gasp for air, the vibration noise startled me. Personal experience suggests 15 km/h is a safe threshold, though it varies by car. My current Nissan can handle down to 10 km/h without issues, but my friend's Volkswagen requires at least 12 km/h. At low speeds, using a higher gear puts heavy load on the engine, increases fuel consumption, and may even wear out the transmission. Beginners are advised to watch the tachometer—if it drops below 1000 RPM, be alert. Usually, rely on your senses; if the engine sound becomes muffled, downshift quickly. Be extra cautious on mountainous roads—don't stubbornly stay in second gear at low speeds. Over time, you'll naturally develop the habit.

Having driven manual transmissions for over 20 years, the minimum speed for second gear varies by vehicle model. My old car could handle down to 10 km/h, while the new one needs at least 15 km/h to stay stable. Don't go too slow - insufficient engine torque may cause stalling or carbon buildup. Once when my speed dropped below 10 km/h, the car shook violently until I immediately downshifted to first gear. Always listen to the engine: when the sound becomes labored, check your speed. In heavy city traffic, shift flexibly to keep RPMs above 900.
