How many seconds is the maximum allowed for semi-coupled starting in Subject 3?

[SanAndrew]

Subject 3 examination regulations stipulate that the continuous clutch depression time should not exceed 10 seconds (5 seconds in some provinces and cities). Relevant information is as follows: The specific reasons are as follows: This means the clutch depression time before and after gear shifting should not be too long, otherwise it will result in immediate failure. Except for starting and gear shifting, there is no need to keep the foot on the clutch pedal. Keeping the foot on the clutch pedal for extended periods can easily cause prolonged semi-clutch state, leading to high temperatures and damage to the clutch friction plates. Additional information: Do not skip gears when upshifting. Skipping gears during upshifting will result in a mismatch between speed and gear ("low speed with high gear"), causing severe vehicle body vibration and potentially stalling the engine. While skipping gears during upshifting is prohibited, accidental wrong gear shifts may occur during driving, such as shifting from 1st to 4th gear instead of 1st to 2nd gear. Therefore, extra attention is required during upshifting.
