Question:

How can you start moving without rolling backward?

1. Put on the parking brake whenever necessary.

2. Engage the clutch before removing your foot from the brake.

3. Apply the hand valve.

4. All of the above

Answer: All of the above

Explanation
If you have a manual transmission vehicle, partly engage the clutch before you take your right foot off the brake. Put on the parking brake whenever necessary to keep from rolling back. Release the parking brake only when you have applied enough engine power to keep from rolling back. On a tractor-trailer equipped with a trailer brake hand valve, the hand valve can be applied to keep from rolling back.
