Where's Bunny? #5

The kids took this photo of Bunny on a road sign (don't worry, we chose a quiet road with a sign set far off the shoulder). I've cropped the photo so you can see Bunny but not the entire road sign.

Do you know what kind of road sign this is?

I'll add a clue in the comments tomorrow if no one posts a guess today.

Game Rule Reminder: The first person to POST A COMMENT (it doesn't count if you email me) about Bunny's location (or answer the question posed) in the photo, wins a "really cool glitter pen" from MaineToday.com (a direct quote from L.). Anyone can win so if you know the answer, post it (and don't forget to include your email address).
