Knowing the referee signals is to your advantage. It will help you play well in the game, improve your rugby and win more games.
Learn from mistakes.
Whenever the referee detects a breach of the rules signals are given by the referee to help players and spectators understand which rugby rules have been broken and what mistakes were made.
If the referee blows the whistle at the same time it means play must stop.
Sometimes there may be no whistle and play continues under the rule of advantage. The referee just gives the signal and so everone knows what is happening.
It`s useful and sometimes important to know what the signals mean. If you were the player making the mistake (and I doubt that very much!), make a mental note to correct and improve that part of your game.
Give away as few penalties as possible - you`ll win more games.
Always keep facing the opposition so there are no surprises!
Simply accept the referee's decision. Only in extremely rare situations would it be changed!
It`s traditional to respect the match officials decsisions and show respect by addressing them as "Sir". What you do to with a female match official - say "Maam"? Sorry it hasn`t happened to me!
Avoid dissent and ill-discipline.
Object to a penalty and you may find the position of the penalty is moved 10 metres nearer to your goalline. It could increase the odds of success with a penalty shot at goal. It could cost you the game.
