The DPS Texas Driving Handbook (pdf) - which is where I got the above graphic - doesn't really answer the question. (And there's no way I'm hitting the Texas Transportation Code when someone out there knows the answer.)
I brought this up to someone before, and they thought it was a no brainer that the signs were the equivalent of maximum speed signs on the highway. But if that's the case, why are they yellow?
Edit: And for you knuckleheads that think I don't understand the basic speeding statute, I at least educated myself four years ago.
