That is true in the NBA. In amateur basketball, the raised hand (with a fist if a foul is ruled) is the signal to stop the clock.

NFHS 5-8: Time-out occurs and the clock, if running, must be stopped when an official: Signals a foul, held ball, violation, timeout.

Rule doesn't state audio or visual signal, implying a level of redundancy.

Also, at one point NCAA did use precision timing, based on sound of the whistle, not the movement of an arm.

Maybe not, but the mechanics state that the hand in the air is the stop clock signal. The whistle is more like an attention getting device, not a signal. If that little pea fell out of your whistle you should be able to yell really loudly and put your hand up with similar effect.

Agree. Of course, the "yell" is also an audio signal.

In the case of a non-functioning whistle (spit it out, dropped it, etc.) the visual signal alone should stop the clock, and if high school ever has a future replay monitor, one should be able to check the time with a visual signal.

Yeah, hate to admit it, but I've done both.

NFHS 2.4.3 SITUATION: Prior to the game, the home team athletic director informs the officials that the school has purchased a new timing system whereby the game clock is controlled by the game officials via their whistle and a timing pack. RULING: The device shall not be used unless the state association has approved its use and the game officials have been properly instructed/trained on how to use the equipment. (2-4-3 Note)

... with no high school replay monitor, if I had a "spit my whistle out" (non-functioning whistle) episode, and I got a good look at the clock as I put my arm up, I would have no qualms about adding time to the clock as I had definite knowledge, this being not limited to, but especially in, an end-of-period situation.

My IAABO signal chart states that, but my IAABO Mechanics Manual states that one should simultaneously sound one's whistle and give a visual signal.

I don't have access to a NFHS Mechanics Manual.

NFHS Officials Manual

Violations: Give a sharp single blast of the whistle and fully extend one arm above the head with fingers extended to stop the clock.

Fouls: Sound the whistle with a single sharp blast while raising one hand, fist clenched, straight and high above the head.

I was actually just thinking of the chart but do agree that the whistle and the hand go up together according to the actual written section of the mechanics.

"Signals"?

It could be a tap on the shoulder. A physical touch. "Excuse me young man, that was a travel".

When I find an old hard boiled egg that rolled to the back of the refrigerator, a "signal" to me that it could be bad is its odor.

I'm trying to think of an odor that officials could emit as a signal, but choose not to bring that to a final conclusion.

How is this relevant? In the rulebook and mechanics manual, "signal" has a specific meaning. A signal is a specific movement of the hand(s) and/or arm(s), occasionally of a foot, to indicate a specific action related to the game (signalling a foul, violation, timeout, or other stoppage of play (held ball/jump ball)).

Rich1 is right that the signal and whistle happen, or at least ought to happen simultaneously. The reason is that the timer can react to the visual signal if he failed to hear the whistle (or the whistle fails to sound). If there is only the whistle, but no visual signal to stop the clock, it is possible that the timer may not stop the clock on time. The reason why this is a moot point at higher levels is because they have special technology allowing the game and shot clocks to stop when the whistle is blown.

At the NFHS and lower college levels, it is important for officials to signal that the game clock is to stop, to avoid such errors. At the Division 1 level, with precision timing, stopping the clock with a signal is important for redundancy, in case the whistle fails to sound, and for instant replay, to correct timing errors.

I contend that the word "signal" in the actual rule is used as a generic verb (as opposed to the NFHS and IAABO "signal" charts, in which case it's used as a specific noun), and can be a visual signal, and an audio signal (and I also joked about a physical touch, or an odor, as a signal).

While most high school timers may (note that I said "may") be real good at watching for officials to "chop in" time, I seriously doubt they all actually watch for visual signals to stop the clock.

This "special technology" is allowed in high school games (under certain conditions), but is almost never used.

Again, the word "signal" in the actual rule is used as a generic verb and can be a visual signal, and an audio signal.

Also, I agree fully with ilyazhito's statement about audio and visual signaling redundancy.

No signal needed for some violations in NCAAW. All levels.
