An exterior rearview mirror assembly for a vehicle includes a bracket fixedly secured to the vehicle, a mirror casing secured to the bracket and defining a primary opening, and a primary mirror disposed within said primary opening for providing a view rearward of the motor vehicle through a primary field of view. The primary mirror defines a primary plane. A spotting mirror is spaced apart from the primary mirror and extends through a secondary plane different from the primary plane. A divider extends between the primary mirror and the spotting mirror to separate the primary and secondary mirrors visually.
