The Blindside Helper^TM is the add-on mirror that allows seeing the right side of the truck’s blind side angle. 

It’s large mirror surface has riveted Velcro® straps that are to be fixed on the passenger’s side sun visor.

Conceived and created by truck drivers in order to help improve on blind side backing up manoeuvre.  Noticing that such a product is inexistent and unavailable, they took the initiative to commercialise it.
