TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your inquiry of July 16, 1971, concerning supplemental mirrors.

Federal Motor Vehicle Safety Standard No. 111 does not prohibit the installation of a supplemental outside mirror on the passenger's side. The Standard does stipulate certain field of view requirements for both the inside and driver's outside mirror, but the manufacturer is certainly free to exceed these field of view requirements with additional mirrors.
