Need Fed Test Q32 references

[chartrusepengui]

Another stupid question on part one exam NFHS.

Q32 - " A simultaneous violation is called if offensive players occupy the first marked lane spaces and defensive players occupy the second marked lane spaces during the free throw."

OK - A) True - but how can any good official even allow this to happen without doing some preventitive officiating? "hey guys - blues on the bottom"

Anyway - can anyone help me with the supporting references other than 8.4 a-f

This tells about free throw administration but says nothing about double violation.
