Car gear speed ranges are as follows: 1st gear: Used for normal starting or climbing steep slopes, speed generally around 10km/h. 2nd gear: Transition gear for acceleration after starting, or for low-speed driving, speed generally around 20km/h. 3rd gear: Used at speeds of 20-40km/h, commonly used for city driving. 4th gear: Used at speeds of 40-60km/h. 5th gear: Used at speeds of 60km/h. Additional information: Automatic transmission vehicles also have P, N, D, S, L gears. P stands for Parking gear; N stands for Neutral gear; D stands for Drive gear; S stands for Sport gear; L stands for Low gear.

As someone with over a decade of driving experience, I frequently navigate between city streets and highways. The speed ranges for manual transmission gears are actually quite flexible: 1st gear is mainly used for starting up to within 15 km/h, providing stability when launching at traffic lights; 2nd gear covers 15-30 km/h, ideal for urban turns; 3rd gear handles the medium-speed range of 30-60 km/h, such as cruising on main city roads; 4th gear manages 60-90 km/h, transitioning to highway speeds; while 5th or 6th gear is suitable for speeds above 90 km/h, especially for fuel efficiency on highways. Factors like engine size and vehicle weight influence this—my compact car can reach 20 km/h in 1st gear, but with my friend's heavier SUV, it's best not to exceed 15 km/h in 1st gear. Remember not to force high speeds in low gears, as it strains the engine excessively, and when descending in high gears, control braking carefully to avoid unexpected skidding. For daily driving, I advise beginners to frequently check the tachometer and adjust speed accordingly—this protects the car while ensuring smooth and safe driving.

I've been pondering car gears for quite some time, and the speed ranges aren't set in stone: in manual transmission cars, 1st gear is generally used below 20km/h for stable starts, 2nd gear for 20-40km/h to cruise easily on city streets, 3rd gear for 40-70km/h as the common mid-speed range, 4th gear for 70-100km/h when preparing for highways, and 5th gear for efficient cruising above 100km/h; automatic transmissions are simpler, with the D gear automatically adjusting across the full range from 0 to over 200km/h. The key is the vehicle model—lightweight sports cars have broader gear speed ranges, with 1st gear potentially pushing up to 40km/h, while regular family cars are more conservative. Engine torque is also crucial; low-torque cars should downshift more cautiously on inclines to avoid stalling due to insufficient power. It's advisable to shift gears according to road conditions: use the highest gear at high speeds to reduce fuel consumption, and avoid frequent acceleration and deceleration in city traffic to protect the transmission.

When I first started learning to drive, I was confused about the gears. Later, I understood the basic rules: for manual transmissions, 1st gear is used for starting at 0-15 km/h, 2nd gear at 15-30 km/h for daily commuting, 3rd gear at 30-60 km/h for medium-speed cruising, 4th gear at 60-90 km/h for high-speed preparation, and 5th gear for cruising above 90 km/h. Automatic transmissions are more convenient, with the D gear covering all speeds from 0 to the upper limit. Each car is slightly different—my friend's small car can reach 20 km/h in 1st gear, while my old car is limited to 10 km/h. The speed range is heavily influenced by the engine, and small-displacement cars require smooth transitions between gears to prevent jerking. For beginners, I recommend practicing more on flat roads to avoid shifting incorrectly at high speeds and damaging the car.
