To start moving without rolling back on a hill, the technique of partially engaging the clutch before releasing the brake allows for a smooth transition from a stationary position to moving forward without the risk of rollback. This technique utilizes the friction created between the clutch and the engine, giving you a chance to control the vehicle's movement while placing it in gear.

When the clutch is partially engaged, it allows the engine to begin transmitting power to the wheels. As the brake is gradually released, the driver can sense when the vehicle is ready to move forward, allowing a controlled start without the vehicle rolling backward. This skill is particularly crucial in driving situations involving inclines, as gravity can easily pull the vehicle backward if not managed properly.

Other techniques, such as fully engaging the emergency brake, wouldn't enable the vehicle to move forward; shifting into neutral delays the launch and increases the risk of rollback; and applying the brake harder than normal could lead to unnecessary wear on the braking system and does not assist in moving forward efficiently.
