Signs specific to a state

Another possible one for Alaska:  A combined R3-5/left turn yield on green ball.

I'm unreasonably annoyed that you took the time to edit the picture but left the upside down S.

The arrow and the N are also upside-down...

The N is, but American standard arrows are symmetrical along the long axis, so they can't be "upside-down".

And yet, nevertheless, it is.

Some Nevada comments as I'm catching up on this thread:

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).

Are they a different shape than the ones in the MUTCD?

MUTCD W11-19


MUTCD W11-4

My understanding is that the 2009 MUTCD adopted a few animal warning signs that were previously only used in Nevada, the burro warning being one of them. I believe there is a different cattle/steer design used in Nevada than the one shown here, though...not sure if there is a distinctive use case between them though. 

Raleigh signage does something not often seen. The destination of a few freeways is a broad reference that the route will take you to the Northern part of town. I don't often see guidance to general sides of a city.

This is standard practice along I-80 in Nevada. Most towns have three exits: are West Whatever, Downtown Whatever, and East Whatever.

Winnemucca is high-falutin' with its four exits: West Winnemucca, Winnemucca Downtown West, Winnemucca Downtown East, and East Winnemucca.

Interestingly, NDOT District 1 does not follow this practice on I-15, even though there are a few towns north of Las Vegas where they could.

Winnemucca isn't as high-falutin' as indicated, only because the outer exits are actually signed for East/West Winnemucca Blvd.

NDOT policy has recently changed on this, so as signs get replaced they are using street names instead. The most recent example I'm aware of came in the last few years, as they replaced signs on I-80 in Verdi west of Reno during a resurfacing and safety project—here, NDOT installed supplemental signs with the old exit name. Interestingly, at the East Verdi exit, this led to them adding an SR 425 shield and referencing "Old US 40".

NDOT District 1 used to follow the "East/West City" signing practice. Years ago, back when there were only two exits on I-15 in Mesquite, they were labeled as East Mesquite and West Mesquite. Can't recall when they changed those exit signs to use the street names instead (perhaps when they reconstructed the west interchange), but it's been several years.

Missouri's Alternating Passing Lanes signs



I don't think I've seen these diamond signs anywhere else, either:

Is that one in Michigan?

[GaryV]

Michigan has used them in the past (although without the two banners). But they are trying to make most highway passing zones 4-lane, passing lanes on both sides of the road.

Here's one:

It was also in Missouri.

[architect77]

There is an official sign for passing lanes shaped like a paddle or slim triangle. It is yellow. They aren't very common any more but I know NC49 used to have them at brief passing lanes on the very rural highway.

[Thing 342]

Does any state besides VA post mile markers facing backwards from traffic for use in reverse flow during evacuations?

Missouri's Alternating Passing Lanes signs

Interesting. I wasn't aware that US 160 had alternating passing lanes (I refuse to use the term "shared four-lane"). Been a long time since I've gone to that part of the state.

Do other states have "crossing double white line prohibited" signs like these at the I-270/I-70 interchange in St. Louis County? This is the only place I've ever seen them.

I wonder why this is set up like it is. Are backups common here with people crossing over late to avoid them?

Past that, there's this sign, which is somewhat common along one-way frontage road exits in Texas:

It's definitely a very congested interchange, particularly at evening rush hour (lots of commuting back and forth from St. Charles County into the city). This is the only direction that has the double white lines, though, and I'm not sure why that is. The only thing I can think of is that you're traveling uphill (it's a little bit steeper than GSV makes it look) and maybe that causes trucks to get bogged down in stop-and-go traffic, making the backups worse than they would be otherwise.

Texas also has a variation of this sign:

MoDOT also uses this sign where westbound I-70 merges with southbound I-35 in downtown Kansas City. (GSV before I-70 merges and where the double line ends) In this case, it's there to prohibit a triple lane change in ~500 feet to reach the next exit on the right, though of course I still see drivers do it anyway.

Looking at historical Street View, before they put the signs up sometime between 2012 and 2013, the lanes were painted with a wider gore to discourage this movement, but it changed to make room for an auxiliary lane on the right side.

New Jersey: signs associated with jughandles. "ALL TURNS FROM RIGHT LANE", and "U AND LEFT TURNS", the latter of which can be used for a loop-type jughandle, or a standard one where the motorist is instructed to turn left on the sidestreet.  The gore sign "ALL TURNS" used to be unique, but I think that has been added to the MUTCD.

NJ used to have the yellow "BRIDGE MAY BE SLIPPERY" warning sign, but I think those have been replaced with "Bridge Freezes Before Roadway" or something similar.

Ohio: when the 55 mph speed limit was first repealed in the mid-1980s, they put up these divided signs listing the limit as 65, but 55 for trucks under 4 tons empty, and non-commercial busses.  Later on these would be replaced by two standard-type signs side-by-side, then I think eventually they did away with dual speed limits altogether. Here's one such installation.

Delaware has one instance of "ALL TURNS FROM RIGHT LANE" and "U and LEFT TURNS", on a loop jughandle.  I don't remember what year they were put in, but it was decades after the jughandle opened in 1983.

Oregon- "Speed X"

I remember seeing an Oregon-styled "SPEED X" sign on a street in Lewiston, ME either in 2016 or 17 travelling up to a football game back then. That sign is now gone as of 2018 though.

Georgia also has its own homemade looking sign reminding drivers to leave space around big trucks so they'll be seen as well as a fully loaded truck cannot stop as quickly as a passenger car.

New Hampshire, at least on I-95, used to use a variation of this sign.

Ohio used it too, although with an exit tab style panel for the "Don't get a ticket" part.  https://maps.app.goo.gl/oYj4LEcD4bQ86zNN7

I believe the 2009 MUTCD incorporated all of NJ's jughandle signs as standard signs. Can't imagine they are in wide use outside of NJ though.

I used to see a lot of these yellow triangle No Passing Signs growing up in NC, but this is about the only one I can locate today on a map. interesting in that it's mounted on the other shoulder from the intended audience.

Also driving this alternate and shorter parallel route to I-85 from Raleigh to Charlotte is see a small reflector exists on the back of every shoulder sign about 2"x2" so you can see the sign from the other side at night.

^I am pretty sure VA has plenty of those or something similar.

^^ Michigan uses those signs.
