What are the functions of the various gears in a manual transmission car?

Manual transmission gear functions are introduced as follows: 1. First gear is the starting gear, used when the car begins moving from a complete stop. Another meaning of the starting gear is that it's only used for starting - once the car starts moving, you need to shift to second gear. 2. Second gear is the driving gear, used when the car is moving at very low speeds. This means as long as the car is moving slowly without stopping, you can use this gear (not for high-speed driving). Some vehicles with higher idle speeds can even start moving in second or third gear by pressing the accelerator, though this operation is not recommended. 3. Third gear is the acceleration gear. Starting from this gear, you can use the accelerator to increase speed and bring the car to a certain velocity. 4. Fourth gear is the medium-high speed driving gear. On most urban roads (excluding elevated roads), this is generally the highest gear needed. Depending on the vehicle, it's typically used when maintaining speeds around 60-70 km/h. 5. Fifth gear is the high-speed gear, used only on elevated roads or highways, generally at speeds of 80 km/h or above. 6. R gear is the reverse gear, used when backing up the car.
I've been driving manual transmission cars for over a decade and know each gear like an old friend. Neutral (N) is most commonly used when parking at red lights or starting the car—it disconnects the wheels from the engine, keeping the car stationary while the engine runs. Reverse (R) is straightforward, used for backing into parking spots or reversing; just remember to come to a complete stop before shifting to avoid accidents. First gear (1st) is my go-to for starting—it provides strong engine torque, allowing smooth movement by slowly releasing the clutch while adding a bit of throttle. However, don't stick with it too long; shift to second gear (2nd) once you hit 10-15 mph for better acceleration. Second gear is great for quick acceleration up to around 20 mph, like when crossing intersections. Third gear (3rd) is ideal for cruising at moderate speeds, comfortable and fuel-efficient around 30 mph in the city. Fourth gear (4th) handles higher speeds, perfect for commuting at 40-50 mph. Fifth or sixth gear (5th/6th) are your highway gears, keeping the engine quiet and fuel-efficient at speeds over 60 mph. The key is matching the gear to your speed—avoid high gears at low speeds to protect the engine, and don't rev too high in low gears to save fuel. Manual transmissions offer flexible control, safety, and cost savings, making them my daily commuting companion.
When I first started learning manual transmission, it took me a long time to figure out the functions of each gear. Now I understand: Neutral (N) is mainly used when parking, such as idling the engine at a red light. Reverse (R) is specifically for backing up, and you need to firmly press the brake to prevent rolling when operating it. First gear provides the most power, making it ideal for starting or climbing steep hills; after starting in first gear, I accelerate to 10-15 mph before shifting to second gear to continue speeding up. Second gear allows flexible acceleration around 20 mph; third gear is suitable for steady driving at 25-35 mph; fourth gear is used for medium-high speeds above 40 mph; fifth gear is for fuel efficiency and a quieter engine at around 60 mph on highways. Beginners often stall the car by shifting gears incorrectly, but with practice, I learned to shift smoothly and not rush. Manual transmission taught me how to control speed safely and effectively.
