Found this in North Little Rock:

No Left Turn

GPS: Turn left onto E 22nd St.

"But, I- I can't turn left..."

GPS: Turn left damnit!

You can't turn left coming south because there is no road there. You can turn left coming north, though.

Isn't the sign referring to E 22nd St, which is approximately 100 feet ahead on the left?

I realize it's not exactly opposite the signalized approach on the right, but it's pretty clear what the intent is.

I wonder why the restriction? (I think I can guess, but it seems excessive not to be time-based.)

More to the point, where's the redundancy? And also, how is it repetitive?

[bzakharin]

E 22nd Street has a separate no left turn sign at the actual intersection

Oh...well, I guess that's redundant, if intentionally so. No different than an advance turn assembly followed by a junction assembly, really.

I would have to say it is considering there is another no left turn sign at the street and right under the no left turn sign on the light post it says E 22nd St.

I've posted the equivalent of this with US highways before, but this was the first I'd ever seen it with a state route:

Bad resolution, but 2 warnings of a curve within 200 feet of each other. Both have a right curve at 45 mph reccomended. Redundant as this one curve is the only one for the next 1.5 miles and was 2 signs really necessary for this?

GSW had not been updated to show both signs and both signs have been up for a year or so.

Perhaps they were having issues with drivers missing the turn, so they installed another sign. I've seen this a few times in Pennsylvania.

This is not redundant. It's allowed in the MUTCD standards for curves.

See page 111.

I'm not seeing on Table 2C-4 (which page 111 suggests I should refer to for spacing guidelines) where less than 200 feet is specified for any speed limit dropping down to a 45mph warning sign situation.

Assuming I'm reading the chart correctly...

75 mph dropping to 45 mph = 550 feet
65 mph dropping to 45 mph = 400 feet
55 mph dropping to 45 mph = 275 feet

I don't follow..."redundant" and "allowed" aren't antonyms. Indeed, many redundant things aren't just allowed, but essential (such as a spare parachute).

[Hurricane Rex]

Its allowed I thought, but stuff that's allowed can be redundant.

Probably should be 20 MPH.

Exit 1C on I-464 southbound in Chesapeake, VA, which is non-existent. There's only Exit 1B (I-64 East, Inner Loop) and 1A (I-64 West, Outer Loop), then it changes to Exit 15 (US-17 South) once it transitions onto VA-168 South.

VDOT really wants you to know that this is the way to I-64 & VA 143

This is a remnant of when VA 104 was still signed and the Oak Grove Connector was not yet built.  EXIT 1C was for VA 104 (the straight ahead movement).  Carbon copying does not help here.  VA 168 should also be added to the overhead signs.

VDOT has been doing this for 30-35 years, especially on divided arterials.  I guess they want to make sure both lanes see the signs.

Reminds me of heading south on US 231 in Blountsville. Upon enter the town limits, the speed limit drops to 35 MPH:

But then, a few hundred feet later...

^^ The school speed limit is either more enforceable or fines are higher in a school zone.  Probably had to put up a sign even though there is no reduction of speed.

I'm guessing it's related to the fact that cops tend to enforce speed limits more strictly in school zones (and work zones and speed traps) than elsewhere on the road, generally.

[mrsman]

Another possibility is that the main speed limit was at one time higher, but then got reduced and they did not adjust the school speed limit sign.

I believe that it is confusing to have a school speed limit sign without a speed reduction.  They could have a sign that warns of the presence of a school, like the yellow pentagon sign, without mentioning the speed, since it is irrelevant.  [It seems the yellow pentagon sign is there, so the school speed limit should be removed.]

In my area, this is how it's done in areas where the main road is 25 all times (and no corresponding reduction is necessary since school zones are default at 25).
