Title: Non-MUTCD-compliant W1/2 turn/curve warning signs?

The MUTCD can't possibly have every scenerio coded and shown in their manual. Modifications to advisory signage is perfectly fine and isn't considered a non compliant sign.

True. MUTCD allows for combination horizontal and intersection warning signs in section 2C.11. It would seem that the "standard" signs of the MUTCD for the combo signs are meant to convey examples of possible configurations.

However, section 2C.46 seems to indicate that at least some of the more typical side road warning signs linked in the original should only show two symbols.

Quote from: MUTCD 2C.11
Section 2C.11 Combination Horizontal Alignment/Intersection Signs (W1-10 Series)

Option:
01 The Turn (W1-1) sign or the Curve (W1-2) sign may be combined with the Cross Road (W2-1) sign or the Side Road (W2-2 or W2-3) sign to create a combination Horizontal Alignment/Intersection (W1-10 series) sign (see Figure 2C-1) that depicts the condition where an intersection occurs within or immediately adjacent to a turn or curve.

Guidance:
02 Elements of the combination Horizontal Alignment/Intersection sign related to horizontal alignment should comply with the provisions of Section 2C.07, and elements related to intersection configuration should comply with the provisions of Section 2C.46. The symbol design should approximate the configuration of the intersecting roadway(s). No more than one Cross Road or two Side Road symbols should be displayed on any one combination Horizontal Alignment/Intersection sign.


Standard:
03 The use of the combination Horizontal Alignment/Intersection sign shall be in accordance with the appropriate Turn or Curve sign information shown in Table 2C-5.

Quote from: MUTCD 2C.46
Guidance:
07 The Intersection Warning sign should illustrate and depict the general configuration of the intersecting roadway, such as cross road, side road, T-intersection, or Y-intersection.
11 No more than two side road symbols should be displayed on the same side of the highway on a W2-7 or W2-8 symbol sign, and no more than three side road symbols should be displayed on a W2-7 or W2-8 symbol sign.

The signs you speak of will normally be located on back roads.  When people travel, they're generally on main roadways and highways. Unless your travels take you on back roads, which is generally unusual unless it's from the highway to your destination, you're probably not going to see them.

Not necessarily. I can't link this because I'm on mobile right now, but on US-206 in Peapack-Gladstone, there's a pair of intersection signs for Old Dutch Rd and Deer Haven Rd that resembles the Orthodox Church symbol.

But a side road on a curve is common.


Variation on a W1-10.  My only comment is that the side road should be thinner than the mainline, but other than that I see no problem.

I wonder how common signs like these are outside of NJ. From what I've seen, not so much actually.

The signs you speak of will normally be located on back roads.  When people travel, they're generally on main roadways and highways. Unless your travels take you on back roads, which is generally unusual unless it's from the highway to your destination, you're probably not going to see them.

Not necessarily. I can't link this because I'm on mobile right now, but on US-206 in Peapack-Gladstone, there's a pair of intersection signs for Old Dutch Rd and Deer Haven Rd that resembles the Orthodox Church symbol.

Thanks.

In Pennsylvania, I've encountered numerous of these nonstandard curve warning signs–which, in my experience, are usually standard curve signs with appendages added to the arrow representing side roads.

Just off the top of my head, here's one I used to encounter daily: https://goo.gl/maps/qmUCwD2EhSnkyx8o7
And nearby in the opposing direction: https://goo.gl/maps/najptDuaxsTuvwxZ7
Farther down the same road: https://goo.gl/maps/j4CE5pLqFvtZ7fZw6
One I recall from childhood: https://goo.gl/maps/GST7KZj3vQsyWxQD8

I'm sure I could come up with a very long list of PA examples if I had the time and inclination.

And there's also this one (location unknown) that I saw in an old FHWA video on FedFlix and posted to the "Unique, Odd, or Interesting (https://www.aaroads.com/forum/index.php?topic=11045.msg2142877#msg2142877)"  thread a few years ago:

Ah yes.  Seems like the "intersection" signs don't use arrows, where as curved signs do.  Except Intersections are involved with curved signs as well.  So like what I found on my search, it pointed me to the intersection signs, not the curved signs.

Back to this again?  The sign is compliant. The MUTCD is a guide, not a bible, and signs need to vary based on what exists.  If the sign was on a white background, or a octagon, then it wouldn't be compliant.

That sign isn't even non-MUTCD-compliant anyway.  The MUTCD specifically allows up to two side roads to be indicated.

Quote from: MUTCD – 2009 edition
Section 2C.11 – Combination Horizontal Alignment/Intersection Signs (W1-10 Series)

Option:
   01   The Turn (W1-1) sign or the Curve (W1-2) sign may be combined with the Cross Road (W2-1) sign or the Side Road (W2-2 or W2-3) sign to create a combination Horizontal Alignment/Intersection (W1-10 series) sign (see Figure 2C-1) that depicts the condition where an intersection occurs within or immediately adjacent to a turn or curve.

Guidance:
   02   Elements of the combination Horizontal Alignment/Intersection sign related to horizontal alignment should comply with the provisions of Section 2C.07, and elements related to intersection configuration should comply with the provisions of Section 2C.46. The symbol design should approximate the configuration of the intersecting roadway(s). No more than one Cross Road or two Side Road symbols should be displayed on any one combination Horizontal Alignment/Intersection sign.

Standard:
   03   The use of the combination Horizontal Alignment/Intersection sign shall be in accordance with the appropriate Turn or Curve sign information shown in Table 2C-5.

Reminds me of analyzing bridges in my statics class.

Both connection points are pin connected, and all segments are rigid (but the one on the right is obviously not straight). There is 400 lb of tension in the top left line (the diagonal one), and each segment weighs 100 lb. What is the force in the horizontal line?

(No, I didn't solve this myself.)

Probably that and our roads go every which way.  A few years back, they phased out the older side road signs that used a narrower line to indicate the side road/lower priority road..

It isn't entirely clear if that's MUTCD-compliant or not (well, if the trunk line had an arrowhead, that is).  The MUTCD provision for making custom combination signs limits them to "no more than one Cross Road or two Side Road symbols".  So the question is this:  does "one cross road and one side road symbol" fall within that limit or not?
