I have very limited experience at formal rifle ranges perhaps your knowledge base here is different than mine. I do have experience with pistol training both professional and recreational. All the times I have shot a rifle at a range with others whomever needed to go down range would announce that fact to everyone and get acknowledgement from everyone prior to doing so. Once that person was safely behind the line they would announce that fact and everyone could go on about their business.

In carbine or shotgun classes I would imagine that it would be handled the same as it is in a pistol class. No one leaves the line until the range master says so.

In any case it can't hurt. I just feel that if we are relying on safety colored clothing to keep us safe at the range we have missed a few fail safes along the way. It takes no extra effort to throw on a safety vest or colored shirt so if it helps it helps.
