Doesnt appear to be the case - don't know of to many tractors that have a break controller that can be applied from the drivers seat to stop the trailer being pulled ;-) As I said the wording of the laws are really not all that clear.
"Every trailer or semitrailer when operated upon a highway at a speed in excess of twenty-five miles [40.23 kilometers] per hour must be equipped with safety chains or brakes
adequate to control the movement of and to stop and to hold such vehicle and so designed as to be applied by the driver of the towing motor vehicle from its cab, and said brakes
must be so designed and connected that in case of an accidental breakaway of the towed vehicle the brakes are automatically applied."
