Can You Not Pull the Handbrake When in P Gear?

You can choose not to pull the handbrake when in P gear because the P gear is both a neutral gear and has a braking mechanism. Therefore, the direct function of engaging P gear is for parking. When stopping on a level road, engaging P gear puts the car's transmission in a neutral operating state, completely interrupting the power transmission between the engine and the output shaft. When driving an automatic transmission car, you can shift to N gear when waiting at a red light, instead of staying in D gear and pressing the brake. In the event of a rear-end collision, if the car is impacted and forced forward while in D gear, it can easily damage the transmission. Therefore, if the wait at a red light is prolonged, it is advisable to shift to N gear and engage the handbrake.

I've always believed that it's best to engage the handbrake when parking in P mode. The P mode relies on a locking pin inside the transmission to secure the car, but if the handbrake isn't engaged, especially when parked on a slope or uneven ground, this locking pin bears the full weight of the entire vehicle. Over time, this can easily damage the transmission. Moreover, if the road is slippery or there's a minor collision, the car might roll, leading to an accident. Engaging the handbrake adds an extra layer of safety, distributing the pressure to protect the vehicle's components and ensuring the car remains as stable as a mountain. Forming this habit is simple—just pull the handbrake before turning off the engine. From a safety perspective, having dual protection is far more reliable than relying solely on the P mode. If an accident happens, it's no small matter. Taking a second to engage the handbrake when parking brings peace of mind and protects your car.

When driving an automatic transmission car, I've encountered many drivers who take shortcuts by only shifting to P (Park) without engaging the handbrake. On flat ground, it might be fine, but parking on a slope can lead to trouble. Once, I parked on a slope without using the handbrake, and the car slid nearly half a meter, scraping against a roadside post—I regretted it deeply! Since then, I've always made sure to engage it. The P gear's locking pin isn't foolproof; bearing too much weight can wear out transmission parts, but using the handbrake eliminates this risk. Additionally, parking spaces in the city are tight, and if there's any movement around, the handbrake can prevent the car from rolling and causing harm or damage. Making this a habit ensures peace of mind and saves money by avoiding unnecessary repairs.

When parking in P gear, the transmission's parking pawl engages with the gear to lock the vehicle. If the handbrake is not applied while parked on a slope, the locking pin bears the entire weight of the car, which can accelerate wear or damage over time. Applying the handbrake distributes the pressure and protects critical components. Additionally, starting the car becomes smoother, avoiding jerks. In short, using the handbrake is a wise choice that enhances safety.
