When parking a vehicle with manual transmission, which gear should be selected?

When parking a vehicle with a manual transmission, selecting the "Low" or "R" (Reverse) gear is crucial for ensuring the vehicle remains stationary. In the event that the parking brake fails, having the vehicle in a low gear or in reverse can help prevent it from rolling, as it engages the engine's compression, which provides resistance against the vehicle moving downhill.

Choosing to park in low gear offers an extra layer of security, especially on inclines, because it helps to hold the vehicle in place more effectively than in neutral. If the vehicle were parked in neutral, there would be no resistance to rolling, making it unsafe. Hence, parking in "Low" or "R" gears is a common best practice for manual transmission vehicles, providing stability and enhancing safety.
