Never mind, I just found 5-4-3b1b.


AIM 5-4-3.b.1.(b) states; "If approach course crossing is imminent and the
pilot has not been informed that the aircraft will be vectored across the
final approach course, the pilot should query the controller." It does not
say "the pilot is required to query the controller" or "the pilot must query
the controller". Even if it did, the AIM itself says it's nonregulatory.
