What do the first, second, third, and fourth gears mean?

[SanBrynlee]

Here is an introduction to the gears of a manual transmission car: 1. First gear: The starting gear, used when the car begins moving from a stop. Another meaning of the starting gear is that it is only used for starting. 2. Second gear: The driving gear, used when the car is moving at low speeds. 3. Third gear: The acceleration gear. From this gear onwards, you can use the throttle to accelerate, increasing the car's speed to a certain level. 4. Fourth gear: The medium-high-speed driving gear. On most city roads, except for elevated roads, this is generally the highest gear used, typically when the vehicle speed is maintained around 60-70 km/h. 5. Fifth gear: The high-speed gear. Used only on elevated roads, highways, etc., generally when the speed is 80 km/h or above. 6. R gear: The reverse gear, used when reversing the car.
