Which gear should be used for manual transmission when going uphill?

When driving a manual transmission car uphill, it is generally appropriate to use 3rd gear. However, if the car is carrying heavy loads or passengers, it is recommended to use 2nd gear. The specific gear choice should be determined based on the vehicle's overall power performance, road conditions, slope gradient, and the driver's experience. Manual transmission, also known as a manual gearbox, requires the driver to manually shift the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed variation. The working principle of a manual transmission is: by using the shift fork to change the gear engagement ratio, the driving torque is adjusted to suit different driving conditions.
I often drive manual transmission cars on mountain roads, and experience tells me to always use a low gear when going uphill, ideally first or second gear. Lower gears allow the engine to deliver more power, preventing the car from rolling back or stalling. When starting on a slope, I usually engage the handbrake first, then partially release the clutch while applying a bit of throttle, and only release the handbrake when I feel the car has enough forward momentum. This method is safe and reliable, especially on rainy days or steep slopes, as it reduces the risk of rolling back. Avoid using higher gears for climbing hills—third gear and above will strain the engine, causing RPMs to spike, which not only wastes fuel but can also damage the engine. For small inclines in the city, second gear may work, but for steep mountain slopes, first gear is safer. Practice on empty slopes to get familiar with your car's feel—once you're comfortable, driving becomes much easier.
