Do Automatic Cars Need to Engage the Handbrake When Parking?

Automatic cars need to engage the handbrake when parking, especially on slopes, as it prevents the car from rolling. Parking procedure for automatic cars: When parking on level ground, follow this sequence: shift to N (Neutral), release the foot brake, engage the handbrake, shift to P (Park), and turn off the engine. When parking on a slope, follow this sequence: shift to N, firmly engage the handbrake, release the foot brake, shift to P, and turn off the engine. Precautions when using the handbrake: The handbrake mechanism is a ratchet system. Pulling it too tightly can cause the steel cable to undergo plastic deformation, which is irreversible. This increases the handbrake's travel distance and reduces its braking effectiveness. The handbrake should not be used as a substitute for the foot brake at high speeds, as it primarily controls the rear wheels. Engaging the handbrake at high speeds can easily cause the car to flip. Do not forget to engage the handbrake when stopped on a slope in traffic, as this can prevent the car from rolling. Avoid driving with the handbrake engaged, as this causes excessive wear on the brakes, leading to reduced braking performance.
From a safety perspective, I always insist on applying the handbrake when parking an automatic transmission car. After driving for over 20 years, I've witnessed too many accidents caused by cutting corners. While the P (Park) gear does lock the transmission to prevent vehicle movement, it primarily relies on internal gear mechanisms. If parked on a slope or uneven ground, these gears endure additional stress leading to accelerated wear. The handbrake, as a mechanical brake, directly acts on the wheels, providing dual protection for parking. Especially when parking on steep slopes, failing to engage the handbrake may result in slight vehicle movement that could hit obstacles or even injure pedestrians - posing significant safety risks. I've developed the habit of using the handbrake every time I park, even on level ground. This isn't a hassle but rather an excellent way to prevent accidents. Since adopting this practice, I've never encountered any rolling car issues.
As someone with a good understanding of automotive mechanical structures, I believe using the parking brake can protect the transmission and extend vehicle lifespan. The P (Park) gear locks the vehicle using gears, but if you don't engage the parking brake when parked, the gears experience uneven stress during gear shifts when starting the vehicle, accelerating wear. Through personal testing, I've found this practice significantly reduces transmission lifespan and increases repair costs. Using the parking brake reduces strain on the drivetrain, acting like an additional protective layer for the car. For instance, I don't use it during brief stops at red lights, but always engage it for any prolonged parking. This simple habit prevents potential failures, especially in urban stop-and-go conditions, saving considerable repair headaches.
When I first started driving, I often forgot to engage the handbrake. Later, a small incident helped me correct this habit. Once, I parked on a slope in a supermarket parking lot without using the handbrake, and when I returned, the car had rolled a short distance and bumped into another car—luckily, it was just a scratch. An experienced driver friend told me that the P gear isn't always reliable, and the handbrake is the real safeguard. Now I've learned my lesson and make it a habit to engage the handbrake every time I park, no matter the location. This simple action—just moving your hand—can prevent accidental rolling. New drivers shouldn't find it troublesome; safety should always come first.
