I teach classes for beginner referees. I seem to recall, from the murky past, specific instructions for referee signals when indicating free kick versus throw-in direction. Specifically, should the referee face the touchline when signalling (for throw in) as opposed to facing the goal line (for free kick)?
I’ve looked thru the Guidance and ATR and can’t seem to find anything.
This is probably trifling, but I’d like the proper citation nonetheless.
Answer (August 23, 2013):
All signals without exception are given while standing square to the field. As for assistance in instruction, you should look through the various online materials in the referee Resource Center at ussoccer.com — including a detailed “show and tell” video on AR signals.
