Caltrans External Exit Tabs & 240 Inch Tall Overhead Signs
Max Rockatansky:
I was kind of liking how the exit tabs in-sign were getting messed up like this:

I think the left mounted exit plaques are there to show a maximum wind loading situation. The left side plaques will be twice as tall as a right plaques to allow for a LEFT plaque to be placed above the exit number.

Haha, yeah that sign looks great :p
The FHWA has given a hard no to using in-sign exit tabs:

^^^
Even more reason why Exit 23.9 is the best thing to happen Interstate 15 and Zzyzx in decades. Really MUTCD adherence and California (both Caltrans and the DOH) have never really ever seen eye to eye on much of anything. That’s why it totally wouldn’t shock me if the left Exit tab as illustrated above is real.
FWIW the above statement shouldn’t be taken as a complaint by me about MUTCD adherence in California. I love interesting and weird signs, California has certainly been a treasure trove over the years.

Digging a little deeper, it looks like right exits will have right aligned plaques and left exits will have left aligned plaques. No center aligned plaques here. :p
--- Quote ---Exit number (E1-5P) plaques should be added to placed above and abutting the top righthand edge of the sign for an exit to the right.
Standard:
Because road users might not expect an exit to the left and might have difficulty in
maneuvering to the left, a left exit number (E1-5bP) plaque (see Figure 2E-22) shall be
added to placed above and abutting the top left-hand edge of the sign for all left-hand exits
(see Figures 2E-14 and 2E-15). The word LEFT on the E1-5bP plaque shall be a black
legend on a yellow rectangular sign panel and shall be centered above the word EXIT.

In that case the FHWA needs to start looking at Washington, Illinois, etc. (As far as I know, Georgia no longer has any left-exit signs with in-sign exit numbers.)
