Your conclusion may be correct, but your reasoning isn't quite. Rather, one
cannot conclude by what was done that it is permitted to be done.

[Although if you mean "can" literally, as opposed to "may", then you'd be
correct grin.]

There've been incidents there before regarding trucks and aircraft, at least
one of which involved an aircraft being cleared onto a taxiway inhabited by
a truck.
