Pig spotter 2's are legal but must be installed correctly in order to view behind you. For instance I set mines up this way. I only use the right mirror when switching lanes so that one is setup for viewing the right lane. The left side I always look over my shoulder so it pointed more towards the rear of the bike so I can view behind me easier. If both mirrors are setup to view lanes on the side of you it will be difficult to view behind you. If that is a big concern for you then I would stick with conventional mirrors with some aftermarket flare.
