Let me try clear things up a little, folks.
This vehicle was swinging so forcefully that the toad on the dolly was visibly moving the towing vehicle side to side; enough so anyone driving it could not help but notice their situation.
Despite this, he soldiered on, travelling well over 60 MPH on a busy four lane highway. He obviously had no concern whatsoever with the possibility that he might just go out of control and be the cause of a serious accident.
I could care less how old a rig is, or a toad either, provided they are well maintained and driven responsibly. This was neither.
