You will take a drug test the first day. One reason orientation takes so long is to get the results of your drug test back. That doesn't mean that what they discuss doesn't have value, but they won't put someone in a truck, regardless of experience, until they pass the drug test. To keep you from being bored, they fill the time with videos, lectures and answering questions. You will learn who to speak with concerning pay, dispatch, safety, etc., You will also need to be prepared to account for the previous 10 years work history. If you haven't worked that long, then they will help you with that. The Feds require that they gather a 10 year work history from all drivers. This is pretty much what happens at most of the larger carrier's during orientation.
I took the Smith System and I still remember the 5 keys. Lets see... they were the ignition, door, side box, glove box, and trailer padlock keys. :lol:
