In South Africa they have a couple of different names for speed bumps - most common is "speed humps" but my personal favorite is "traffic calming devices".
This photo is of an African speed bump - don't know about you, but this doesn't do much to calm me at all! And yes, that is a MASSIVE SNAKE!
This photo was not taken by me or anyone else I know...hopefully it is from a part of Africa God will not call us to visit!
