All I can think of is 150 (degrees) R(ight). As opposed to left. I must be missing SOMETHING here. Help!

On our curvy roads here in the mountians we often have yellow diamonds with numbers on them, just before the curves. The numbers warn you how slow you *should* be going. The scariest curve on the mountain has a 10 just in front of it, on the other hand I don't even slow down for the ones labled 40.

Originally Posted By Schmitty Good Vibes I don't have enough info to know what you are talking about, but (as a Caltrans expert) this might help: "R" always refers to "Route". Except the "R" should always come first, not follow. Whenever we use a number followed by an "R", it means the route has been revised. For example, roads are often straightened, so the old location is no more, it has been moved some distance due to the change in the road. So exit 142 is now exit 142R. Somehow I'm guessing that neither of these is your answer, so could you elaborate?
Originally Posted By Mr X Sorry, I can't elaborate any further since that's all he told me (unless I'm being confusing..if so I apologize). I'm beginning to suspect that he saw this only in Japan and simply misremembered seeing it in America too. Heck, I've been all over the country and I don't ever recall seeing such a thing. Perhaps it's simply a Japanese roadsign thing (although that, too, would be bizarre since there is no "R" in the language and they don't tend to write signage using Roman letters anyway). Sorry for the frustrating topic, guys. Appreciate the input!
