Hmmm, I generally remember those in construction zones. Have they started putting them elsewhere? And generally don't those say "Strictly Enforced"? The implication being that they will bust you even for 56 in a 55 (generally, again, because it's a construction zone). Finally, I seem to remember that the issue is that California has a relatively (couple years old) new law that a speed limit must demonstrate that it is at the 80% point or has an explicitly documented exception or it's challengable. Presumably, these signs fall into the "explicitly documented exception" category.
