Should an automatic transmission car be turned off first or shifted to P gear first when parking?

[StAnnie]

For an automatic transmission car, shift to P gear first when parking. Nowadays, more and more car models cannot be turned off without shifting to P gear. The P gear has an additional locking gear compared to the N gear. When the car is shifted to N gear, it can move if subjected to external force. However, when shifted to P gear, the locking gear can secure the gear on the transmission’s output shaft, preventing the car from moving even under external force, thereby fixing the stationary vehicle. Shifting to P gear before turning off the car is a safety consideration. Before shifting to P gear, always engage the handbrake first, as only the handbrake can truly prevent the car from moving. When the vehicle is subjected to external force, engage the handbrake first to bear the force, then shift to P gear to let the P gear bear the force.
