Will the car roll back when stalling in first gear on a slope?

Normally, the car will not roll back when stalling in first gear on a slope unless there is insufficient power, which may cause it to roll back. Preventing rolling: If the car is on an uphill slope, in addition to engaging the handbrake and putting the car in a forward gear, placing stones or other objects behind the wheels can ensure the car does not roll back. Conversely, if the car is parked on a downhill slope, engage the handbrake and put the car in reverse gear. Because the gear rotation direction in the transmission is different, the reverse gear can lock the gear rotation to prevent rolling. To avoid unexpected situations, it is also advisable to place stones or other objects under the wheels. Manual transmission on a slope: If a manual transmission car stops on a slope, the driver must simultaneously press the clutch and the foot brake. Shift to neutral. Engage the handbrake.
Once when I was driving uphill, I accidentally stalled the car while it was in first gear. I was extremely nervous, but to my surprise, the car didn’t roll back at all—it stayed firmly in place. This happens because when the car is in first gear, the gears in the transmission lock up, creating a resistance similar to braking. Especially in manual transmission cars, even if the engine stalls and stops running, the wheels and engine shaft remain connected through the gears. The backward force from the slope is blocked, preventing the car from sliding. Of course, this is just an emergency backup and shouldn’t be relied upon entirely, as there’s still a slight risk if the slope is too steep or the gears are worn due to the car’s age. I remember quickly pulling the handbrake to finally relax—safe driving is always the priority. During driving practice, instructors often remind us to use the right foot brake in coordination with the clutch for hill starts to avoid stalling issues.
