TITLE: FMVSS INTERPRETATION

TEXT: This is in response to your January 17, 1977, letter concerning the requirements of Safety Standard No. 111, Rearview Mirrors, for passenger cars. You requested confirmation of your interpretation that the standard specifies no requirements for outside rearview mirrors on the passenger's side of the vehicle when the inside rearview mirror meets the field of view performance requirements of paragraph S5.1.1 of the standard.

Your interpretation is correct. If the inside rearview mirror of a passenger car meets the specified performance requirements, the vehicle is not required to be equipped with an outside rearview mirror on the passenger's side. However, a manufacturer is free to equip its vehicles with outside right-hand mirrors, either plane or convex, if he choses.

You should note that each passenger car whose inside rearview mirror does not meet the field of view performance requirements of paragraph S5.1.1 must have an outside rearview mirror of unit magnification installed on the passenger's side of the vehicle.

SINCERELY,

BMW OF NORTH AMERICA, INC.

Federal Motor Vehicle Safety Standard, FMVSS 111, Paragraph 5.3, states that "each passenger car whose inside rear view mirror does not meet the field of view requirements of S 5.1.1, shall have an outside rear view mirror of unit magnification installed on the passenger side . . . " (emphasis added).

In Paragraph S 5.3, the emphasis is placed on the inside rear view mirror, which does not meet the field of view requirements of S 5.1.1.

It is BMW's understanding that the outside rear view mirror on the passenger side, whether of unit or non-unit magnification, does not fall within the jurisdiction of FMVSS 111, when the vehicle's inside rear view mirror meets the field of view requirements of S 5.1.1.

Your confirmation in writing of this understanding would be appreciated.
