TITLE: FMVSS INTERPRETATION

TEXT: Thank you for your letter of December 4, 1968, to Mr. Eugene Laskin regarding Motor Vehicle Safety Standard No. 111 on rearview mirrors.

Your interpretation and enclosed figure 1 are not entirely correct. The 35 foot distance is measured horizontally, not at an angle. The plane must be tangent to the vehicle -- not tangent to the mirror. The measurement is made at the road surface 35 feet to the rear of the projected eye position and 8 feet outward from this plane.
