FROM: JOHN WOMACK -- ACTING CHIEF COUNSEL, NHTSA
TO: KENNETH A. GALLO -- HOWREY & SIMON
TITLE: MICHO INDUSTRIES AND SAFETY RESEARCH MANUFACTURING INC. EXEMPTION PETITION
ATTACHMT: ATTACHED TO LETTER DATED 12-18-92 FROM KENNETH A. GALLO TO MARION C. BLAKEY (OCC 8128)
TEXT: This responds to your petition of December 18, 1992, on behalf of your clients, Micho Industries and Safety Research Manufacturing, Inc. The petitioners are manufacturers of an item of motor vehicle equipment called the "R-Bar Restraining System." They asked for an exemption for the R-Bar
from compliance with the testing procedures set forth in 49 C.F.R. Sec. 571.222 subsections S5.1.4(c) and S5.1.4.1 & 2 (1991) for purposes of determining whether the R-Bar (when attached to a passenger seat) deflects to within four inches of any part of another passenger seat.
The petition was submitted pursuant to 15 U.S.C. 1397 (a) (2) (B). Alternatively, you request consideration pursuant to 15 U.S.C. 1410 (a) (1) (B). Preliminarily, let me note that the provisions of section 1397 (a) (2) apply to vehicles originally manufactured to conform to the Federal motor vehicle safety standards but which are subsequently modified before or after their sale to a first purchaser for purposes other than resale. Section 1410 (a) applies to a vehicle at the time of its manufacture.
Section 1397 (a) (2) (A) provides, in pertinent part:
No manufacturer, distributor, dealer, or motor vehicle repair business shall knowingly render inoperative, in whole or in part, any device or element of design installed on or in a motor vehicle . . . .
Section 1397 (a) (2) (B) provides that:
The Secretary may by regulation exempt any person from [subparagraph (A)] if he determines that such exemption is consistent with motor vehicle safety and the purposes of this chapter. The Secretary may prescribe regulations defining the term "render inoperative".
Thus, your petition asks, in effect, that manufacturers, distributors, dealers, and motor vehicle repair businesses be permitted to install the R-Bar in a school bus in use, even if the installation may cause the vehicle to no longer comply the installation may cause the vehicle to no longer comply with the requirements of Standard No. 222. Although section 1397 (a) (2) (B) was added to the National Traffic and Motor Vehicle Safety Act (the "Act") in 1974, yours appears to be the first formal request for an exemption that the agency has received, and is therefore a case of first impression. Although NHTSA has provided advisory letters over the years interpreting "render inoperative," the NHTSA has not prescribed any "regulation" pertinent to section 1397 (a) (2).
Congress did not write into the statute any limitation on the use of the section 1397 (a) (2) (B) exemption authority apart from specifying that any exemption must be consistent with motor vehicle safety and the purposes of the Act. However, the committee report in the House, where the exemption provision arose, suggested a limited scope of authority. The report stated that "exemptions may be warranted for owners with special medical problems, who require special controls, or for emergency vehicles or police cruisers." While these purposes were not expressly incorporated in the statute as limitations on the exemption authority, the agency believes that it would not be appropriate to issue an exemption based on other grounds unless there were a strong, compelling reason to do so.
NHTSA does not believe that there is a strong, compelling basis for granting your clients' petition under section 1397 (a) (2) (B). Indeed, NHTSA believes that the concept of using "safety bars" as occupant restraining devices in school buses raises significant safety concerns that would need careful evaluation before the agency would take any action to facilitate their use.
One concern is whether the bar could result in excessive loads (e.g., abdominal, leg, or chest) on occupants during a crash, as a result of contact between the bar and the occupants. This is a complicated issue involving many variables, including type of crash (e.g., frontal, rear), positioning of occupants (sitting up straight, leaning forward, slouching, etc.), what happens when a large occupant is seated next to a small occupant (which could affect the position of the bar relative to the small occupant), and what happens if books, brief cases, lunch boxes, etc. are placed beneath the bar or on top of the bar (thereby affecting the position of the bar relative to the occupants and/or movement of the bar during a crash). Another concern is whether the bar could result in excessive loading of occupants' heads during a crash, from head contact with the seat back in front of the occupant, instead of loading that is spread more evenly over the occupant's body.
I note that NHTSA does not have the information that would be necessary to assess your client's product in relation to these safety concerns. The agency has not conducted any testing of safety bars, and the very limited test information submitted with your client's petition does not provide a basis to make such an assessment. It is clear, however, that Standard No. 222 has been effective in ensuring a high level of occupant protection in school buses. NHTSA believes it would be inappropriate to take any action to facilitate the use of a device that potentially could reduce school bus occupant protection.
Please note, as we have advised others, the prohibition in section 1397 (a) (2) (A) does not extend to the owner of the vehicle. If a school bus authority has its own private service facilities, the installation of the R-bar by the service facilities would not violate the prohibition. However, in view of our discussion above, we would not encourage a school bus authority to make that installation.
The petitioners have also asked to be exempted pursuant to section 1410 (a) (1) (B). This section excuses a noncompliance if the exemption would facilitate the development and field evaluation of new motor vehicle safety features which provide a level of safety which is equal to or exceeds the level of safety established in the standard from which exemption is sought. However, a petitioner under section 1410 (a) must be the manufacturer of the new motor vehicle for which an exemption is sought. Thus, NHTSA can not consider your clients' petition under that section. The agency would be able to consider a petition under section 1410 (a) (1) (B) that is submitted by a school bus manufacturer which wished to install the R-Bar in its vehicles. However, any such petition should address the safety concerns discussed earlier in this letter.
We are returning the videotapes and two of the three copies of the petition that accompanied your letter. If you have any further questions, you may call Taylor Vinson of this office (202-366-5263), who spoke with you previously on this matter.
