I guess a CDL mill or rip off company would charge $2000. for a refresher but I know that State tech. schools charge only around $500.00 for a refresher. $2000 is too much money to pay for something you all ready own in your wallet! and besides, you don't have to take a entire CDL course just to get a refresher!
this is if you have no driving time at all.........but as i said, class B driving counts now for time/experience, even military time. and actually, although 1 year is ideal, 6 months with one company OTR is good enough to get a more localized driving job. but personally, i'd recommend staying the one year too......makes a driver "look" more committed to the job.
