What is the consequence of rolling back more than 12 inches during a stop?

Rolling back more than 12 inches during a stop can significantly impact vehicle control. When a vehicle rolls back, it can indicate a lack of proper brake engagement, which raises safety concerns. A rollback of this magnitude suggests that the driver is unable to maintain a secure position on an incline or slope, leading to a higher risk of losing control of the vehicle. This scenario can jeopardize the safety of both the occupants of the vehicle and others nearby, as it may result in unintended movements that could cause accidents or collisions.

Hence, the classification of control as 'Bad' accurately reflects the dangers associated with excessive rollback, emphasizing the importance of mastering vehicle control techniques, especially in varying terrains.
