Here is my favorite sign on the island of Hawaii. Evacuation Route!
Now in case of emergency I am not sure if this is the evacuation route for lava flow or a tsunami.
What is great about the location of this particular sign is that it is partnered with another road sign. I guess you can choose which way you want to evacuate. Good times.
Here is another interesting sign from the Magic Sands beach of Hawaii.
"If In Doubt, Don't Go Out."
Basically there are huge rocks right where the waves are breaking. However this did not seem to stop anyone from body surfing and boogie boarding in the water.
