Why is riding the clutch (resting your foot on the pedal or slipping it to hold position) harmful?
- A.It keeps the clutch partially engaged, wearing it rapidly, building heat, and risking loss of drive or rollback on grades
- B.Riding the clutch cools it
- C.It is the correct way to hold on a hill
- D.Clutch wear is unaffected by pedal habits
Correct answer
A. It keeps the clutch partially engaged, wearing it rapidly, building heat, and risking loss of drive or rollback on grades
Why
A slipping clutch converts engine power into heat and wear instead of motion, and it can fail suddenly when it finally overheats. Holding position belongs to the brake; the clutch is for starting and shifting only.
