What is the minimum speed for 3rd gear?

[StKing]

3rd gear speed should not be lower than 20Km/h, with the corresponding speed range for 3rd gear being 20-40km/h. Gear introduction: 1st gear: Starting gear, used for vehicle launch. It has similar gear ratio and performance to reverse gear, thus not suitable for prolonged high-speed operation. Generally, you can shift to 2nd gear once the vehicle gains momentum. 2nd gear: Passing gear, mainly used for navigating complex road conditions and handling difficult situations, such as sharp-angle (right-angle) turns without special obstacles, crowded urban areas, steep slopes, and bumpy roads. 3rd gear: Transition gear, primarily used for low-speed urban driving. Depending on circumstances, it can easily transition up to 4th gear for acceleration or down to 2nd gear for deceleration. 4th gear: Cruising gear, mainly used for prolonged high-speed driving and economical operation. Most vehicles achieve their most fuel-efficient speed in the low-speed range of 4th gear. 5th gear: High-speed gear, mainly used for long-distance highway driving.
