It's admittedly (probably) not from Colorado, yeah. Though the important part you need to read is really the hours, since the other stuff doesn't tend to vary. Which they helpfully used a smaller font for, to make sure so you don't forget to squint at the most relevant part.
It's definitely distracting to have so much text, since you're still supposed to quickly read all of it, just in case it might say something other than what you expect. Not sure how that's supposed to work at 65+ mph.
And helpfully those words are much much larger.
I will note that signs like that don't exist in my area.
