I'm not saying this is set in stone especially since I'm still in school myself. But, One of our instructors told us we could also use the Trailer Hand Valve (Johnson Bar) to also help keep from rolling back.
To be honest I don't think I would bother using it though. Using the Johnson bar only engages the trailer service brakes where as using the brake pedal utilizes both the tractor and trailer service brakes. Seems like a better idea to use both.
So yeah ease up of the clutch until you feel the friction point, ease up of the brake while coming off the clutch at the same time.
You do the same thing in a manual transmission car to keep from rolling back when stopped on a hill. Let your clutch hold you in place.
I don't think that would be allowed in your CDL test.....but I'll let someone with more info validate that.
CDL:
