How do you pronounce a "DOT" physical for truck drivers? Is it said like one word, dot, or is it said "D. O. T"?
I drive big riggs for UPS and we say D.O.T.
Personally, I think you should pronounce it as one word since if you say it as the individual initials, you might confuse someone. However, if you are in an official conversation you should pronounce it as D.O.T.
Letters, not as a word.
Department Of Transportation. D. O. T
D.O.T not dot
