You pretty much gotta prove yourself that your capable of running the ride, its not something everybody gets trained at, ultimately the driver is in charge of the ride, they got to know all emergency procedures, and be able to carry them out if need be. Also TR:TR is the only ride you got to show you know what yoru doing to even get trained to check restraints, another hint dont keep asking the CT's to get trained at a position every day becasue if you do, you most likely wont get trained because it becomes fun to watch you ask all the time (I think phil knows what i mean).
