Your truck has a manual transmission, and you had to stop on the shoulder of an uphill grade. What is a good practice when you start moving up the hill again?
Correct answer: Hold the truck with the parking brake until the clutch engages.
Answer options
- AAllow the truck to drift back a short distance, then let out the clutch
- BHold the truck with the parking brake until the clutch engages Correct
- CSlip the clutch the whole time as you slowly add power
Why
The parking brake keeps the truck from rolling backward while you let the clutch out and give it power; release the parking brake once there is enough power to keep from rolling back. Riding the clutch wears it out quickly, and letting the truck roll back is dangerous.
