What gear should be engaged when parking on a downhill slope?

[SanLilah]

When parking on a downhill slope, engage neutral gear and firmly apply the handbrake. Alternatively, you can shift into first gear and firmly apply the handbrake to prevent the car from rolling. For automatic transmission vehicles, first firmly apply the handbrake and then shift into P (Park) gear. Automatic transmission vehicles have P (Park) and N (Neutral) gears, both of which can be used when parking. The P (Park) gear is used when parking and turning off the engine, while the N (Neutral) gear is used for short-term parking without turning off the engine. When P (Park) gear is engaged, the locking mechanism locks the transmission gears, effectively locking the wheels indirectly. Even without applying the handbrake, the car will not move. The N (Neutral) gear does not have a locking mechanism, so if the handbrake is not applied after shifting into N (Neutral), the car may roll.
