I agree. In the military you cant train until you prove you can train the trainer. I think that any truck driver wanting to train should have to take out a trainer and show off their teaching skills and be signed off on by a experienced trainer. What happens when you get someone who doesn't listen or react well to your style of teaching? You just going to give up? Kick them out of truck? My father tried to teach me years ago and we argued more than trained lol.
