Is 3 weeks of training enough?

Three weeks isn't enough. Three years isn't enough.

Keep your eyes open, watch how others secure, don't follow too close, don't stand near a crane doing a lift, don't scratch the paint, carry spray cans in JD green, Cat yellow, CASEIH red, don't cut the straps use edge protectors, don't stand beside a load of pipe when you unstrap it, belly wrap, know the securement rules, GOAL, inspect your truck and load often.....even when you're walking back from the restaraunt.......never stop learning, watching, listening.

Do all of that and when something goes wrong at least it won't be a catastrophe.
