Hikari

This just looks like a regular curve sign to me.

Yui

Close, but it's "Reverse Bend"—an S-shaped pair of curves going opposite directions. A single bend is different, and three or more curves would be a winding road.

Hikari

So it's warning me I'll zigzag twice?

Yui

Yep! Slow down before you hit that S-curve so you don't overshoot either turn.
