At what level of body vibration can a hill start be initiated?

[LaAdam]

Hill start requires the vehicle to vibrate to the semi-engaged clutch state. Concept: Hill start is a field test in the second subject of the driver's license examination, which involves starting a vehicle parked on a steep slope upwards. After positioning the vehicle correctly, the test technique is to firmly pull up the handbrake and then pull it two more times to ensure the handbrake is tightly secured to avoid rolling back. Technique: Shift to first gear, release the handbrake, gently release the clutch, and proceed up the slope once the vehicle is stable. Try to stay within 30 centimeters of the side line, control the clutch as much as possible, and keep the vehicle speed as slow as possible. For the stop at the designated point, use a reference object aligned with the marker pole to ensure the front of the vehicle is aligned with the pole, thus achieving accurate positioning.
