On a side note I strongly advise anyone who is close to getting called to get their cdl before hand. Most people wind up passing the DMV road test after the mta training but there are some that don't and sometimes they make u requalify for mta if u fail the DMV road test. That is not stress you want to deal with. Getting thru the mta training is very stressful, don't add more to it, get your cdl before hand. If you can't afford it ask a family memeber or close friend to burrow their credit card and just pay them back every month and then take them to a nice dinner for helping you out. Trust me get the cdl before hand.
There was a girl on my training bus, she qualified for the mta day 7, the earliest day possible.... she wound up failing both of her DMV road tests and was forced to resign from the mta. Trust me get the cdl ahead of time, I can not stress this enough.
