Dealing with traffic safety, this particular sign is being engulfed by the surrounding jungle. Is this sign important? Yes, very much so. I had to take this picture across the road, because one can barely make it out in the lane it faces, due to the greenery, in the right of the picture, blocking the view.

Keeping in the jungle, this next picture does not exactly require a "Caution" sign, but some tourist most likely slipped and twisted his ankle. The rocks on the left are sitting in a path, so maybe this sign deserves its placing just in case some fool cannot properly see the rocks.

In the case that a trail or slope should not be traveled on, the little backpacker with a No Trail is labeled. Unless you have rope or know what you are doing, I strongly suggest obeying the sign.

This Caution sign is a handy reminder that leaves and flowers are slippery. It also serves to help enforce the previous sign in which the leaves cover the entire passage by foot.

Some signs warn people of hazards they face, others inform people of creating hazardous circumstances in which geese are run over, because people apparently run over geese.

This sign has significant meaning to me. I was walking around in Volcanoes National Park, and I came across a rock pile which I knocked over. My friends quickly pointed out that I was going to be cursed by Pele. I was like "Umm... I am pretty sure people do not suppose to build rock piles. In an hours time, I had my proof : ).

In Volcanoes National Park, I came across a more worn and serious sign.

If one reads the previous sign and chooses to not advance, then they cannot capture a No Parking sign surrounded by an old lava flow.
