Dockworkers that have went through the program have went and trained during the day and still worked outbound at night. There was no way mathematically that they could have put in a those type of miles PLUS the school was always during the day - no linehaul running.
Did the school 6 or 7 years ago after getting my cdl (about 3 weeks in) ran full p/d runs for all but the last week on linehaul averaged 750 mi a week for 5 weeks
Not sure if all locations are the same but they made sure we seen it all
