What Are the Reasons for a Car Rolling Back on a Hill Start?

[Brady]

There are generally three reasons for a car rolling back on a hill start: 1. The handbrake is not tightened enough: When parking on a slope, the handbrake is engaged, but once the foot brake is released, the car rolls back. This happens because the handbrake wasn't tightened sufficiently. Some people tend to pull the handbrake with the same force as on flat ground when parking on a slope, which is incorrect. The handbrake should be pulled tighter on a slope than on flat ground to prevent the car from rolling back. 2. Releasing the brake too early: Rolling back during a hill start occurs when the clutch is not yet at the semi-engaged position before the brake is released. 3. Releasing the handbrake too late: If the handbrake is not released in time when reaching the semi-engagement point, it can cause the car to stall and roll back.
