What do the 12345 gears in a car represent?

[VanAva]

The 12345 gears in a car refer to: 1st gear is the starting gear, used when the car begins to move, and generally switches to 2nd gear once the car gains momentum; 2nd gear is the passing gear, mainly used for navigating complex road conditions and handling complicated situations; 3rd gear is the transition gear, primarily for low-speed driving in urban areas; 4th gear is the driving gear, mainly used for prolonged high-speed driving; and 5th gear is the high-speed gear, mainly for long-distance highway driving. Lower-numbered gears are low gears, while higher-numbered gears are high gears. The smaller the number, the greater the traction and the lower the speed; the larger the number, the smaller the traction and the higher the speed.
