Trucker uses a well placed arm flail to keep a motorist from smashing into an obstacle coming over the hill
A trucker uses an expertly placed arm flail to keep a motorist from smashing right into some oversize equipment coming up the other side of a hill.
In the video, a four wheeler is driving along a rural road when a truck driver passes him, waving frantically out of his window to get the attention of the motorist. The motorist soon realizes that the driver’s arm flail was meant to keep him from smashing into a large piece of farm equipment making its way up the hill.
“I only knew to slam the brakes because the man in the semi truck was flailing his arm out the window at me. I couldn’t see what was coming otherwise,” the motorist wrote in the video post.
Watch the video that ends happily thanks to a trucker, below.
Lets play a game: ‘what would FSD do’ in this scenario? Has anyone ever driven with it around large agricultural equipment? I pass machinery of this size almost daily – is that an edge case?
