(1) I think that you are 100% correct.
(2) I think (repeat: think) that young people might say:
I saw the truck driver checking me out.
P.S. I am sure that you realize that "giving me the once-over"
and "checking me out" must be used with great caution. It
often (almost always?) implies looking at someone with
(how do I say this?) romantic feelings.
