How long to release the brake when the car shakes during hill start?

[LaRose]

Release the brake when the car shakes for about five minutes during hill start. Here are the relevant details: 1. On the slope: The car is braked by the handbrake and will not roll. When starting, turn on the left turn signal, honk the horn, and check the rearview mirror to confirm safety. 2. Press the clutch pedal: Shift into first gear, gently lift the clutch to enter the semi-engaged state. The vehicle has started, and at this point, even if you release the handbrake, the car will not roll back. Therefore, you should release the handbrake as soon as possible and slowly apply the throttle. When the car is moving smoothly, you should fully lift the clutch pedal to allow the clutch to engage completely, transferring the engine's power entirely to the driveshaft to drive the vehicle forward. The shorter the time in the semi-engaged state, the less damage to the clutch friction plates.
