Slow/idle speed under bridges?

I always thought it was mandatory. Nevertheless, I always go slow...
The sign says "idle speed" but that is a relative term when you are in a
12 kt
tide.
If you were truly "idling" you would be going about 7 knots backward.
That's probably why the signs say "idle speed", not "idle RPMs".
