I'm curently studying for Class1 and looking over the exam questions posted on this site for thermo, NA, applied mech etc the answers have refences to DOT# and dates. What do these refer to and where can I find them? thanks

Welcome to Diesel Duck and though I am not able to answer your question, I am sure someone will know.

Hello Joerow,

I often get that question but unfortunately no one knows the answer for sure. I theorize that the reference, is for a book that is out of print, while the newer Reed's probable doesn't correspond to the edition's reference point.

It looks like the dates refer to when that Exam question was on a paper in an Exam. The questions do repeat, it takes a long time for every question to recur, but they do, eventually. Other references look like various reference books.
