The FMCSA will probably get feedback from thousands on this, determining what does,in fact,constitute a yard, and at what speed does a yard now become a road, and if bobtailing only, could in fact be logged on duty, unless the tractor is a tandem, where that would be considered enough tires to now call that a , unit, which requires more maneuvering, but less than when pulling doubles, or a 53’ van, so it would now become actual driving, unless the unit was traveling at an idle, which that would change the declared unit into a yard trailer relocation mechanism which would then be legal as on duty, not driving, with the only exception being if it had enough fuel in the tanks to go over 100 miles.
Or governed at 46 mph?
