So someone posted their favorite sign over on Mastodon, and I replied with what is my favorite sign, the 'No Straight' sign.
First time I saw this was on a new intersection where one side is a highway ramp, and the other a two-way road, apparently 'Do Not Enter' signs weren't enough, so they put one of these up. Honestly, I'm surprised to know its a standard, Missouri isn't exactly known for sticking to standards, whether its abbreviations like LA for lane, or the non-standard all text signs on the road to my house announcing the road closure ahead and the truck ban on it.
