So it looks like mowers in an enclosed trailer need to be strapped down unless there in contact with the front wall and then each mower is in contact with each other and the front wall needs to have certain requirements too. Does anybody know If I am understanding this correctly? The motor carrier laws are almost impossible to fully understand. Another question too, do I have to let an officer into a locked or closed trailer without a search warrant? I cant even find a place to go for a compliance check. I'm looking for the fastest, easiest way to be in compliance.
