When starting an automatic transmission vehicle, you should shift into gear first and then release the handbrake, as this is the safest operating sequence. Below is a detailed introduction about automatic transmissions: 1. Overview: An automatic transmission, as the name suggests, does not require the driver to manually shift gears. The vehicle will automatically select the appropriate gear based on the driving speed and traffic conditions. Generally, there are six gear positions on an automatic transmission car, from top to bottom: P, R, N, D, S, L. 2. Automatic Principle: The automatic transmission uses planetary gear mechanisms to shift gears. It can automatically change gears based on the degree of the accelerator pedal and changes in vehicle speed. The driver only needs to control the speed by operating the accelerator pedal.

















When I first started learning to drive, my instructor always emphasized the importance of sequence: After starting the engine, first press the brake pedal to ensure the car is stable, then release the handbrake, and finally shift into drive or reverse to prepare for moving off. This is to prevent the car from rolling back on a slope or moving unexpectedly. The most common mistake beginners make is rushing to shift gears before releasing the handbrake, which can strain the engine or cause tire wear. I remember one time on a steep slope when I forgot the sequence—the car rolled back and almost hit an obstacle. How dangerous! Now I’ve developed a habit: press the brake → release the handbrake → shift to D → slowly release the foot brake and gently accelerate. This sequence applies to both automatic and manual transmissions. Safety first—spending a few extra seconds checking before moving off is much better than having an accident.

After driving for so many years, I've found there's no strict rule about the sequence, but efficiency and safety are crucial. My usual approach is to press the brake, gently release the handbrake, and then slowly shift into gear to start; with a manual transmission, I press the clutch first before operating. Why release the handbrake first? Because it allows the car to stabilize before shifting into gear, preventing sudden sliding on slopes or engine overload. Once, I was in a hurry and shifted into gear without releasing the handbrake, resulting in a 'clunking' sound from the transmission—heartbreaking for the car. Different models, like automatics, are easier to operate, and electronic handbrakes can even release automatically. In short, developing this habit for simple daily driving saves hassle and protects the car.

I think the starting steps are quite simple: first, sit properly and start the car, press the brake, release the handbrake to stabilize the car, then shift gears to move. The key point of this sequence is to prevent the car from rolling, especially on mountain roads or in crowded parking lots. Manual transmissions require stepping on the clutch in coordination. Don't mix up the sequence to avoid damaging the transmission system. Habitual operation ensures safety and efficiency.

Daily driving experience tells me that releasing the handbrake first is more reasonable. After starting the engine, first press the brake pedal to ensure the car doesn't move, then release the handbrake to disengage the brake, and finally shift into drive or reverse to start. This prevents the car from sliding on slopes or straining the engine. The operation is similar for automatic transmissions; for manual transmissions, additionally press the clutch. Developing this routine not only protects the brakes and transmission but also reduces the risk of accidents. Adjusting the seat and rearview mirrors before starting is also a good habit.

From a safety perspective, you must never shift into gear before releasing the handbrake when driving! On steep slopes or in parking garages, reversing this sequence may cause the vehicle to instantly roll backward, resulting in collisions or personal injury accidents. I've seen cases where people forgot the correct order in a hurry, causing their car to slide several meters and hit a wall. The proper procedure is: press and hold the brake to stabilize the vehicle, release the handbrake to disengage the lock, then shift into gear to start moving. This rule applies to both automatic and manual transmissions. Prevention is the best approach—practice more on flat ground and slopes to familiarize yourself with the vehicle's response.
