South Carolina: keep moving change lanes later
Virginia: unmarked pavement ahead (in construction zones)
MA: "Go Children Slow", "Autistic Caution Child", or anything with similar wording
MA: Thickly settled
MA: "Bookleaf" town line signs
NH: Seat belts required for commercial drivers and those under 18, recommended for all (I forget the exact wording)
TX: Speed limit 85

Used to be ones in CT that said "Deaf Slow Children"
Also CT: Larger yellow SPEED LIMIT AHEAD xx M.P.H. signs
VT: Frost heaves
NC: Burn Headlights When Raining
North Carolina's use of "Reduce Speed Ahead" (instead of "Reduced Speed Ahead") almost qualifies. Almost. But you can find a few in Virginia on I-395 in the express lanes (https://maps.app.goo.gl/EocgutFH8hVvoZ7z7) and on the Dulles Toll Road approaching the main toll plaza (but, oddly, notice the other sign to the right says "Reduced") (https://maps.app.goo.gl/Fmoo3CrrFBqmrcwT8).
A sign that I believe is unique to Virginia is one you see very quickly after crossing into the state: RADAR DETECTORS ILLEGAL.
Oregon- "Speed X"
Two sign styles I don't think I've ever seen outside Florida:
—Signs for electronic toll collection lanes with a banner saying "PREPAID TOLLS ONLY." (https://maps.app.goo.gl/Rinze2TCTwrTwo8H6) (Those are disappearing with the end of cash tolls in Florida.)
—Signs for toll facilities listing payment methods and giving a bunch of ETC system logos (https://maps.app.goo.gl/bfz9N5o9zuQDpJNy6).
This sign used under W1-6 and W1-7 signs is exclusive to Alabama, IIRC:

Both NC 540 and US 74 Byp Monroe have them...
Nevada has a whole host of animal-silhouette warning signs that don't appear in the federal manual. Notable ones are the burro warning sign (what other state needs that?) and the cattle warning sign (normally paired with an "Open Range" plaque).
California and Nevada have their own version of the bear crossing sign that has twice the number of bears as the federal bear crossing sign.
The left-turn-lane signs in Clark County are subtly different from the federal ones, to make it easier to indicate a U turn as a possibility.
Maryland has its "Lane Ends" warning sign with the downward diagonal arrows.

Delaware now has them here and there. One thing I noticed coming back here in 2002 is that Delaware doesn't seem to have any consistent signing practices.
It did have a few distinctive signs, that usually have taken a more conventional form. Still lingering are signs that are yellow on blue, that normally would have been white on green.

That's interesting, because IIRC the NY signs were linked to a specific legal concept of linear vs. area speed limits that either isn't around much or is around much less in the rest of the country (basically, the NY speed limit signs that say "city speed limit X", "area speed limit X", etc. are more than just informational).
The fact that I didn't think of the speed limit signs themselves in the first place probably says something about how well my brain has been functioning this month... I
really need to get more sleep at some point.
A few more from Florida:
- "Crocodile Crossing" (there's a total of around 4 of these I've seen) https://maps.app.goo.gl/AcDh9G9AhyfWmVZ68
- "Thru Lanes" (like express lanes on a toll road, but no extra toll is paid and a transponder is required) https://maps.app.goo.gl/H6ugLbYGdE5vJ8Ex9

These used to be standard signs in the MUTCD. Both were meant to indicate that a special speed restriction applied ahead that differed (usually lower) from the default speed limit.

That prompts me to think of one of my favorite signs. It's on southbound Bonaventure Boulevard in Weston, Florida. But I doubt it's a "state-specific sign" as envisioned by this thread; I assume the local municipality posted it, especially in view of the use of the word "queue." I wonder how many people are confounded by that word, given that I've seen it spelled in such ways as "cue" and "que." The sign you posted makes me think "Line-Cutting Prohibited" would be more to-the-point. But I still like this sign.

Florida sometimes (by no means always) posts yellow warning signs saying "Church." (https://maps.app.goo.gl/g8eRdAVLPjhhMeUJ9) I've never seen that in any other state.

Edited to add: Famous last words. Here's the thread. (https://www.aaroads.com/forum/index.php?topic=9478.msg221758#msg221758) And it confirms these signs are used in other states, so my comment about never having seen them in other states, while an accurate comment, winds up being inaccurate for purposes of state-specific signs.
