humanpole
Poles hold items like stop signs, yield signs, construction signs. A humanpole stands on the highway with things like stop signs, yield signs, construction signs. Humanpoles replace metal and wooden poles in construction areas. What makes them so special, is that drivers are more likely to respond to the sign held by a humanpole over a metal pole. The basic job of a humanpole is to impose the threat of killing a human as opposed to a metal pole. Humanpoles are a suicide trap and are generally seen smoking.
I was driving down the highway when we were reduced to one-lane, I almost killed this guy holding the merge sign standing on the road, it was a humanpole, so I had to slow down.
