Only in this state....

Michigan's diamonds have an M and are always square when independent-mount; on guide signs, they lack the M and 3-digit routes get wider diamonds.

And not a state, but Ontario's BGS and independent mount signs are completely different.

Never really noticed a difference in NY's myself, though the lack of border seems to affect how they look a LOT.

Yep, and to let Steve know, the wider 3dms on the guide signs are not errors.  They are SOP in the state.

I'm aware of this, at least now - if I'm the Steve you refer to, is this somewhere in one of my captions? (I have too many pages to find old errors or assumptions.)

It's all over your Michigan pages. 
I get a bit of a kick out of them as I know you know now.

Greeeeeat. "All over" usually means about 4 places, from past feedback. I'm sitting tight unless anyone wants to help me out, as I'm already running late on another update and have barely started page writing.

I wouldn't worry about it too much.  The first time I saw New Jersey's way of posting shields on guide signs (in photographs), I thought they were mistakes.  I soon learned.  It is amazing what you learn and how different each state still is even with the Federal MUTCD.

8 places, I stand corrected. Also, it's 4:20.

It seems we end up finding that each state is not as unique as we though in many areas.  As I say this, its because I found out after driving through rural Michigan on the state highway system, that all intersections intersecting a state road have a high pressure sodium lamp suspended above them on span wire. 

I have not seen it standard in other places yet, but if no other state has them on a regular basis, then Michigan has one unique road practice.  I must say its a sound idea illuminating all the crossroads or even slightest public side road as a nice night time safety feature.

I concur with "roadman65".  Michigan is the only state I have seen that has streetlights suspended on span wire above intersections.  This is a very good idea.  Very unique.

Only in Louisiana (maybe not totally): Are 3di's squished into 2di shields. I know other states do this, but we seem to have it across the board. I-220 and US 171 come to mind

Louisiana is just compensating for Texas putting two-digit route numbers in three-digit shields.

Only in North Carolina do the white signs advising of an impending drop in the speed limit use the grammatically-correct "REDUCE SPEED AHEAD" rather than the form "REDUCED SPEED AHEAD" (which I maintain is grammatically incorrect because it is the speed limit that is reduced, and we've all seen speed-limit decreases that nobody obeys).

My comment above from December 2012 is no longer accurate: Maryland now has at least one set of "REDUCE SPEED AHEAD" signs on I-270 southbound near the weigh station. I think I saw one somewhere in Virginia a week or two ago as well but I cannot remember where. Odds are it was somewhere out I-66 towards Linden because I haven't gone anywhere to the south in the past few months.
