What is the method for matching speed and gear?

[ValeriaRose]

The method for matching speed and gear is: 1. First gear is for speeds between 0 to 15 kilometers per hour, used for starting the car or going uphill, and is not suitable for prolonged use; 2. Second gear is for speeds between 15 to 25 kilometers per hour, can be used when turning or in special weather conditions; 3. Third gear is for speeds between 25 to 35 kilometers per hour, used when passing intersections or on roads with slight slopes; 4. Fourth gear is for speeds between 35 to 40 kilometers per hour, which is a normal driving speed and can be used when there are relatively more vehicles on the road; 5. Fifth gear can be used at speeds above 40 kilometers per hour, also considered a normal driving speed, and on well-paved roads, the car's speed can be increased by pressing the accelerator.
