TITLE: FMVSS INTERPRETATION

TEXT: Your letter of July 3, 1968, addressed to Mr. George C. Nield, of the National Highway Safety Bureau has been forwarded to my office for reply.

The installation of dual controls on driver education cars is not per se in violation of the Federal motor vehicle safety standards. However, the secondary equipment must meet the same safety standards established for the primary controls. The secondary steering column must fulfill the same requirements made for the primary column as set forth in Federal Motor Vehicle Safety Standards Nos. 203 and 204. The installation of an additional foot brake must not affect compliance with Standard No. 105. However, duplicate compliance with the control location and identification requirements of Standard No. 101 is not required since the "driver" of such a vehicle remain the person seated behind the primary controls. For the same reason the "driver" mirror requirements of Standard No. 111 apply only with respect to the person seated at the primary controls.

Changes may be made to original equipment when necessary for installation of secondary controls but none of the standards requirements specified may be eliminated or adversely affected by the alteration.

You may make available copies of this letter to dealers and interested parties.
