Inconsequential Noncompliance

AGENCY: National Highway Traffic Safety Administration (NHTSA), 
Department of Transportation (DOT).

[[Page 55780]]


ACTION: Denial of petition.

-----------------------------------------------------------------------

SUMMARY: Motor Coach Industries, Inc. (MCI), MCI has determined that 
certain model year (MY) 1988-2022 MCI coaches do not fully comply with 
Federal Motor Vehicle Safety Standard (FMVSS) No. 205, Glazing 
Materials. MCI filed an original noncompliance report dated March 22, 
2022, and amended the report on April 14, 2022. MCI petitioned NHTSA on 
April 14, 2022, for a decision that the subject noncompliance is 
inconsequential as it relates to motor vehicle safety and submitted 
supplemental information on September 2, 2022. This document announces 
the denial of MCI's petition.

FOR FURTHER INFORMATION CONTACT: Jayton Lindley, Safety Compliance 
Engineer, Office of Vehicle Safety Compliance, NHTSA, (325) 655-0547.

SUPPLEMENTARY INFORMATION: 
    I. Overview: MCI determined that certain MCI motor vehicles do not 
fully comply with paragraph S5.1 of FMVSS No. 205, Glazing Materials 
(49 CFR 571.205).
    MCI filed an original noncompliance report dated March 22, 2022, 
and amended the report on April 14, 2022, pursuant to 49 CFR part 573, 
Defect and Noncompliance Responsibility and Reports. MCI petitioned 
NHTSA on April 14, 2022, for an exemption from the notification and 
remedy requirements of 49 U.S.C. Chapter 301 on the basis that this 
noncompliance is inconsequential as it relates to motor vehicle safety, 
pursuant to 49 U.S.C. 30118(d) and 30120(h) and 49 CFR part 556, 
Exemption for Inconsequential Defect or Noncompliance.
    Notice of receipt of MCI's petition was published with a 30-day 
public comment period, on February 21, 2023, in the Federal Register 
(88 FR 10640). No comments were received. To view the petition and all 
supporting documents, log onto the Federal Docket Management System 
(FDMS) website at https://www.regulations.gov/. Then follow the online 
search instructions to locate docket number ``NHTSA-2022-0039.''
    II. Vehicles Involved: Approximately 15,454 of the following 
coaches, manufactured between January 4, 1988, and January 14, 2022, 
were reported by the manufacturer:

1. MY 2001-2021 MCI J4500
2. MY 1998-2013 MCI E4500
3. MY 2017-2021 MCI J3500

9. MY 1988-2001 MCI 102DL3
10. MY 2001-2022 MCI D4000ISTV
11. MY 2000-2001 MCI 102D3ISTV
12. MY 1995-1999 MCI MC12PTV

    III. Noncompliance: MCI explains that the subject vehicles were 
manufactured with a curb view window to the immediate right of the 
driver that has glazing rated AS-5 instead of AS-1 or AS-2, or one of 
the bullet resistant variations of glazing that are specified in ANSI/
SAE Z26. l-1996, and therefore, do not comply with FMVSS No. 205.
    IV. Rule Requirements: Paragraph S5.1 of FMVSS No. 205 includes the 
requirements relevant to this petition. Glazing materials for use in 
motor vehicles must conform to ANSI/SAE Z26.1-1996 (incorporated by 
reference, see Sec.  571.5), unless FMVSS No. 205 provides otherwise. 
SAE Recommended Practice J673 (1993) (incorporated by reference, see 
Sec.  571.5) is referenced in ANSI/SAE Z26.1-1996.
    V. Summary of MCI's Petition: The following views and arguments 
presented in this section, are the views and arguments provided by MCI. 
They do not reflect the views of NHTSA. MCI describes the subject 
noncompliance and contends that the noncompliance is inconsequential as 
it relates to motor vehicle safety.
    On April 14, 2022, MCI petitioned for a determination that the 
noncompliance is inconsequential to motor vehicle safety on the grounds 
that the lower curb view window is sufficiently transparent to allow 
the coach driver to see people or objects outside the coach and is 
equivalent to the transparency of compliant glazing.
    MCI explains that FMVSS No. 205 and ANSI/SAE Z26.1-1996 do not 
permit AS-5 rated glazing to be installed at locations requisite for 
driving visibility. MCI says that NHTSA considers ``requisite for 
driving visibility'' to mean ``every item of glazing that is to the 
immediate left and right of the driver, as well as windshields.''
    MCI's petition includes a schematic showing the exact location of 
the AS-5 rated curb view window on the subject coaches. MCI further 
explains that AS-5 rated glazing ``is not required to meet certain 
performance requirements that are applicable to AS-2 glazing.'' 
However, in their first petition, MCI contended that the AS-5 rated 
glazing installed in the curb view window of the subject coaches 
complies with the 70 percent light transmittance requirement described 
in Test 2 of ANSI/SAE Z26.1-1996.
    MCI believes that the subject noncompliance is inconsequential to 
motor vehicle safety and argues that ``the actual field performance of 
the small curb view window has met the intent of the substantive 
requirements of FMVSS 205 for glazing requisite for driving 
visibility.'' MCI states ``there is no reasonable possibility that any 
vehicle occupant would impact that window in a collision. Moreover, 
there is no reasonable possibility that any person would be ejected 
through the curb view window in a collision, given its location and 
small size.'' For these reasons, MCI focused its analysis on a need to 
ensure a necessary degree of transparency in motor vehicle windows for 
driver visibility. In its April 2022 submission, MCI makes three claims 
in support of their contention that the curb view windows achieve this 
safety need pertaining to driver visibility.
    First, MCI states that the curb view window in which the AS-5 rated 
glazing is installed, ``is not requisite for driving in the forward and 
reverse gears'' but may be used to assist with parking. MCI claims that 
``the value of the small curb view window even for parking is very 
limited--essentially just to identify the location of the curb to the 
driver or identify a person or object between the coach and the curb.''
    Second, MCI states that the glazing used in the curb view window 
meets the requirements for 70 percent light transmissibility, even 
though that is not required for AS-5 glazing. Thus, MCI claims, ``the 
need to ensure a necessary degree of transparency through the glazing 
is achieved.''
    Third, MCI states that while AS-5 glazing is not required to meet 
certain abrasion resistance requirements of ANSI/SAE Z26.1-1996, ``the 
small curb view window has not unreasonably degraded its 
transmissibility through abrasion or other environmental exposures in 
actual field usage.'' MCI provided photos of a sample of the affected 
coaches with its petition to demonstrate that ``the small curb view 
window has retained good visibility, notwithstanding many years of 
service in challenging environmental conditions.'' Furthermore, MCI 
claims that the glazing used in the curb view window ``has not abraded 
excessively over time and remains safe for use.''
    MCI further states that it has not received any customer complaints 
over the last 10 years but acknowledges that NHTSA does not consider an 
absence of complaints relevant when determining whether an instance of 
noncompliance is inconsequential to motor vehicle safety. MCI states 
that the safety risk of the subject noncompliance ``is the potentially 
reduced visibility through glazing that degrades from

[[Page 55781]]

environmental exposure.'' However, MCI claims it has effectively 
demonstrated that ``the glazing in this particular location has 
remained adequately transparent even after years of service in harsh 
environmental conditions.'' Therefore, MCI believes; ``in this case, 
the absence of complaints supports the photographic evidence 
accompanying this petition.''
    At the time of its initial file of petition on April 14, 2022, MCI 
expressed its belief that it would be able to document that the AS-5 
rated glazing on the subject coaches permits 70% light transmittance. 
This belief was based on inspections of actual coaches and observations 
that the visibility through the lower curb view window was comparable 
to visibility through the upper window with AS-2 rated glazing. 
Photographs of the visibility of individuals and objects through the 
lower curb view window from the vantage of the coach driver were 
included with the petition.
    MCI filed a supplemental petition on September 2, 2022, after it 
undertook testing of the subject glazing in an effort to quantify the 
light transmittance through the glazing under the procedures specified 
by ANSI Z26.1-1996. After its testing, MCI disclosed that the lower 
curb view window in the subject coaches does not permit 70% light 
transmittance. The light transmittance when measured under the 
procedures specified by ANSI Z26.1-1996 was approximately 20%. However, 
MCI continues to believe that, due to the relative darkness of the 
stairwell area inside the coach when compared with the relative 
brightness of the ambient environment outside the coach under most, if 
not all, conditions, the lower curb window provides the coach driver 
with a view of the exterior of the coach that is essentially equivalent 
to compliant glazing. In other words, the coach driver will see mainly 
the light from outside, which makes the individuals or objects outside 
the coach visible to the driver.
    MCI concludes by stating its belief that the noncompliance is 
inconsequential to motor vehicle safety and its petition to be exempted 
from providing notification of the noncompliance, as required by 49 
U.S.C. 30118, and a remedy for the noncompliance, as required by 49 
U.S.C. 30120, should be granted.
    VII. NHTSA's Analysis: In determining the inconsequentiality of a 
noncompliance, NHTSA focuses on the safety risk to individuals who 
experience the type of event against which a recall would otherwise 
protect.\1\ In general, NHTSA does not consider the absence of 
complaints or injuries when determining if a noncompliance is 
inconsequential to safety. The absence of complaints does not mean 
vehicle occupants have not experienced a safety issue, nor does it mean 
there will not be safety issues in the future.\2\

Inconsequential Noncompliance, 78 FR 35355 (June 12, 2013) (finding 
noncompliance had no effect on occupant safety because it had no

and the correct deployment of an air bag); Osram Sylvania Prods.

Noncompliance, 78 FR 46000 (July 30, 2013) (finding occupant using 
noncompliant light source would not be exposed to significantly 
greater risk than occupant using similar compliant light source).

Decision of Inconsequential Noncompliance, 81 FR 21663, 21666 (Apr. 
12, 2016); see also United States v. Gen. Motors Corp., 565 F.2d 
754, 759 (D.C. Cir. 1977) (finding defect poses an unreasonable risk 
when it ``results in hazards as potentially dangerous as sudden 
engine fire, and where there is no dispute that at least some such 
hazards, in this case fires, can definitely be expected to occur in 
the future'').
---------------------------------------------------------------------------

    The subject MCI coaches were manufactured with a curb view window 
in the lower portion of the front door of the coach. The curb view 
window glazing material is rated AS-5, as defined in ANSI/SAE Z26.1-
1996. FMVSS No. 205 incorporates by reference the American National 
Standard for Safety Glazing Materials for Glazing Motor Vehicles and 
Motor Vehicle Equipment Operating on Land Highways-Safety Standard 
ANSI/SAE Z26.1-1996 (ANSI Z26.1). FMVSS No. 205 therefore specifies 
performance requirements for various types of glazing and specifies the 
locations in vehicles in which each item of glazing may be used.
    First, NHTSA is not persuaded by MCI's claim that the lower curb 
window is not requisite for driving visibility. The petitioner states 
instead that one of the purposes of the window is to facilitate parking 
along a curb. Parking involves driving in the forward and/or reverse 
gears, so visibility needed for parking is visibility needed for 
driving. Furthermore, NHTSA has two interpretations discussed in more 
detail, below, which involve glazing of similar design/purpose that 
NHTSA found to be requisite for driving visibility.
    In 2008, California Highway Patrol (CHP) inspected the right-front, 
swing-open, entry door and lower curb-side view glazing on a 2008 MCI 
motor coach and noted that the curb-side view window was labeled AS-5. 
CHP asked NHTSA for an interpretation of whether AS-5 glazing is 
permitted in the lower curb-side view glazing on buses. The Agency 
explained in the 2009 interpretation letter \3\ in response to Mr. Cris 
Morgan of CHP that lower curb-side view glazing on doors to the right 
or left of the driver are considered windows that are requisite for 
driving visibility. Therefore, AS-5 glazing is not permitted on buses 
in windows to the immediate right or left of the driver.
---------------------------------------------------------------------------

    \3\ See https://www.nhtsa.gov/interpretations/08-004149-19-nov-08-sa.
---------------------------------------------------------------------------

    On an April 23, 2001, the agency issued an interpretation letter 
\4\ to Mr. Thomas F. Brown concerning peep windows in Mack Trucks. The 
peep window was a small, separate fixed window located below the 
passenger door's main window, near the bottom of the door, which could 
be used to analyze and react to traffic situations near the passenger 
door of a medium or heavy-duty truck. NHTSA determined that the peep 
window was at a level requisite for driving visibility.
---------------------------------------------------------------------------

    \4\ See https://www.regulations.gov/document/NHTSA-2001-9605-0001.
---------------------------------------------------------------------------

    The lower curb-side view window on the 2008 MCI motor coach and the 
peep window on the Mack Truck are in a similar location and provide 
similar visibility to the curb view window on the MCI motor coaches at 
issue here.
    NHTSA agrees with the petitioner that one of the safety 
considerations in evaluating this petition should be that the curb view 
window helps a driver safely operate the vehicle by, among other 
things, allowing visibility of the curb, a person, or an object that 
might be located between the coach and the curb.
    NHTSA is not persuaded by the petitioner's arguments that failing 
to meet the light transmittance and abrasion resistance for this 
glazing is inconsequential to safety. MCI stated in its supplemental 
petition that the lower curb view window in the subject coaches does 
not permit 70% light transmittance. The light transmittance when 
measured under the procedures specified by ANSI Z26.1-1996 was 
approximately 20%. The Agency is not persuaded by MCI's argument that 
the relative darkness of the stairwell inside the coach when compared 
with the relative brightness of the ambient environment outside the 
coach will provide the coach driver with a clear view of the exterior 
of the coach in most if not all conditions. NHTSA can foresee that in 
evening hours or poor weather conditions the visibility through the 
affected window may be impacted due to the use of AS-5 glazing, which 
is more prone to abrasion and has reduced light transmittance. This 
could prove

[[Page 55782]]

especially consequential to safety if a small child or animal is 
standing outside the small curb view window in hours of reduced ambient 
light.
    In addition, AS-5 glazing is not required to meet other performance 
requirements that are applicable to AS-2 glazing and this may 
potentially further degrade its ability to provide a minimum level of 
safety in this application. NHTSA does not accept MCI's assertion that 
it is not reasonably possible for an occupant to impact the curb view 
window in a collision. After making this claim, MCI's analysis focuses 
on only one of the performance requirements for AS-2 glazing--Test no. 
2: Luminous Transmittance. In fact, there are several performance 
requirements that AS-5 glazing is not required to meet but are 
applicable to AS-2 glazing. Specifically, AS-5 glazing is not required 
to meet Tests no. 1: Light Stability; no. 2: Luminous Transmittance; 
no. 6: Impact, Ball, 3.05 m (10 ft.); no. 7: Fracture Test; no. 8: 
Impact, Shot Bag, 2.44 m (8 ft.); and, no. 18: Abrasion Resistance, 
each of which AS-2 tempered glazing must meet. The required tests under 
AS-5 glazing are for the rigid plastic glazing but not for the tempered 
glass. The petition ignores the other performance requirements 
inapplicable to AS-5 glazing without providing sufficient analysis or 
evidence to explain why these other requirements are irrelevant in this 
instance.
    In summary, the curb view window in this petition is similar to the 
glazing described in the interpretations discussed above and is 
requisite for driving visibility. The Agency's findings in its 
evaluation of this petition are consistent with the Agency's 
interpretations letters of 2009 to Mr. Cris Morgan and of 2001 to Mr. 
Thomas F. Brown which indicate that AS-5 glazing is not permitted in 
windows to the immediate right or left of the driver. Further, MCI 
provided insufficient evidence that the other performance requirements 
outlined in FMVSS No. 205 are irrelevant to the safety analysis.
    VII. NHTSA's Decision: In consideration of the foregoing, NHTSA has 
decided that MCI has not met its burden of persuasion that the subject 
FMVSS No. 205 noncompliance is inconsequential to motor vehicle safety. 
Accordingly, MCI's petition is hereby denied and MCI is consequently 
obligated to provide notification of and free remedy for that 
noncompliance under 49 U.S.C. 30118 and 30120.
