Random signs and posters in Jordan

There were three signs / posters that stood out for me as I hitchhiked and caught buses around Southern Jordan: 

1. One signboard at the side of the road (about 20km from Saudi Border): "Hajj congregating place."

2. Another signboard with an arrow pointing to an alternative highway: "trucks and tanks mandatory"

3. In a minibus the driver had a poster of a young Saddam Hussein on the back of the sun visor. Political messages are all the rage.
