A breakaway system can not be installed on anything that does not have brakes.
I have a light utility trailer on which brakes are not installed, and not required by law. It is quite literally impossible to install a breakaway system on that trailer without installing an axle equipped with brakes. It just can't be done!
Safety chains or cables, however, are required by law on ALL ball hitch trailers, including gooseneck hitches. Such chains or cables must be of sufficient strength to hold the rated gross weight of the trailer.
