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

[MacCamille]

When parking on a downhill slope, you should engage the reverse gear. If you are stopping on a flat road, first shift to neutral, apply the handbrake, and then turn off the engine. If you are on a slope, engage the reverse gear (for downhill sections) before turning off the engine to prevent the car from rolling forward. Parking on a slope with the gear engaged is actually an auxiliary measure to the handbrake. If you are still not confident after engaging the reverse gear, you can place a brick in front of the car's tires. Remember to apply the handbrake first, as this acts on the braking system rather than the transmission gears. Engaging a gear on a slope can help prevent the car from rolling, but the primary reliance should still be on the handbrake. The engine braking only serves as an auxiliary function. If the parking slope is particularly steep, placing a brick is advisable.
