Which gear should be used when driving a motor vehicle uphill?

[MacMarley]

When driving uphill, the appropriate gear depends on the climbing power of the vehicle. Each car has different climbing capabilities. For small slopes, use 4th gear if it provides sufficient power; for moderate slopes, use 3rd gear if adequate; for steep slopes, try to use 2nd gear whenever possible. Below are some guidelines for uphill driving: 1. Small slopes: For high-displacement vehicles, drivers can use 2nd or 3rd gear for climbing. For low-displacement vehicles on gentle slopes, 2nd gear should also work without issues. 2. Moderate slopes: Use 3rd gear if it provides enough power; if not, shift to 2nd gear. The shift can be made either at the bottom or during the climb, but proper coordination between the clutch and throttle is crucial. 3. Steep slopes: Regardless of the vehicle's displacement, it's recommended to use 1st gear for climbing as it provides maximum torque.
