SUPPLEMENTARY INFORMATION:

I. Overview

    DTNA has determined that certain MY 2017-2019 Freightliner Cascadia 
motor vehicles do not fully comply with paragraph S6.2.1 of FMVSS No. 
108, Lamps, Reflective Devices, and Associated Equipment (49 CFR 
571.108). DTNA filed a noncompliance report dated January 16, 2019, 
pursuant to 49 CFR part 573, Defect and Noncompliance Responsibility 
and Reports. DTNA subsequently petitioned NHTSA on February 8, 2019, 
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 DTNA's petition was published with a 30-day 
public comment period, on February 27, 2020, in the Federal Register 
(85 FR 11450). 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-2019-0008.''

II. Trucks Involved

    Approximately 74,675 MY 2017-2019 Freightliner Cascadia motor 
vehicles, manufactured between May 3, 2016, and December 17, 2018, are 
potentially involved.

III. Noncompliance

    DTNA described the noncompliance as automatic illumination of the 
stop lamps when the low air pressure warning indicator light 
illuminates. Since low air pressure does not necessarily activate the 
brakes or result in braking without driver intervention, this 
activation of the stop lamps does not meet the requirements of S6.2.1 
of FMVSS No. 108.

IV. Rule Requirements

    Paragraph S6.2.1 of FMVSS No. 108 includes the requirements 
relevant to this petition. No additional lamp, reflective device, or 
other motor vehicle equipment is permitted to be installed that impairs 
the effectiveness of lighting equipment required by FMVSS No. 108.

V. Summary of DTNA's Petition

    The following views and arguments presented in this section, ``V. 
Summary of DTNA's Petition,'' are the views and arguments provided by 
DTNA.
    DTNA described the subject noncompliance and stated its belief that 
the noncompliance is inconsequential as it relates to motor vehicle 
safety.
    DTNA submitted the following background information on how their 
air brake system affects the stop lamps:
    DTNA's air brake system is comprised of two brake systems, primary 
and secondary. The primary system controls the service brakes on the 
drive axles, and the secondary system controls the service brakes on 
the steer axle, in which the higher pressure of these two controls the 
trailer service brakes. These two systems are isolated from each other 
so that if there is an air loss in one system, the other system will 
still be functional to control the vehicle service brakes. When either 
one of the systems drops below 70 psi, the low air warning indicator 
light on the dash turns ON and the stop lamps illuminate. However, if 
this occurs, it does not mean that the drive axle parking brakes being 
applied, since the other brake system may still be functional and 
keeping the brake from applying. In such a situation, the air that 
holds off the drive axle parking brakes would be the higher pressure of 
either primary or secondary air brake. In other words, if the primary 
air brake pressure falls below 70 psi, the indicator light and stop 
lamps illuminate, but the parking brakes do not start to drag since the 
secondary air (presumably unaffected) remains high and holds off the 
parking springs. In the same manner, the trailer parking brakes are 
held off by the higher of either primary or secondary air brake system. 
Only when both air systems drop below about 70 psi will the trailer 
parking brakes begin to apply.
    DTNA submitted the following views and arguments in support of the 
petition:
    1. The normal operating air pressure of the vehicle is between 110 
and 130

[[Page 14326]]

psi. There is a regulator that turns on the air compressor if the air 
pressure is below 110 psi and turns off the air compressor when the 
system pressure is above 130 psi. If the air pressure begins to drop 
and reaches approximately 70 psi, the air system pressure is not 
adequate to maintain optimum operation, so a warning indicator light 
illuminates on the dash and a buzzer activates to alert the driver to 
this condition. On these vehicles, the stop lamps illuminate when the 
warning indiactor light illuminates on the dash. The events induced by 
a low air condition after initial vehicle startup are rare and are not 
expected in normal operation. If the condition were to occur during 
operation, the driver would be alerted to the circumstances with 
audible and visual low air warning signals and would be expected to 
apply the service brakes and pull over in a safe manner. Additionally, 
if the pressure in both air systems drops below 70 psi, the parking 
brakes will slowly begin to apply.
    2. The Freightliner Cascadia Driver's Manual states ``If the low 
air pressure warning is activated, check the air pressure gauges to 
determine which system has low air pressure. Although the vehicle's 
speed can be reduced using the foot brake control pedal, either the 
front or rear service brakes will not be operating at full capacity, 
causing a longer stopping distance. Bring the vehicle to a safe stop 
and have the air system repaired before continuing.''
    3. Brakes are commonly applied causing the stop lamps to illuminate 
when a driver sees a vehicle display warning or senses that the vehicle 
is experiencing a problem. Reducing vehicle speed in relation to a 
vehicle operational problem increases safety, providing following 
drivers the opportunity to increase the following distance. A low air 
warning indicator light would likely cause the vehicle driver to 
immediately engage the brake system and bring the vehicle to a safe 
stop. Stop lamp illumination for a brake system low air event would 
help provide early warning to following drivers to slow down.
    4. DTNA stated, in ``Motorcoach Brake Systems and Safety 
Technologies,'' the Federal Motor Carrier Safety Administration issued 
guidance, while directed toward motorcoach drivers, that supports the 
expectation that a driver, upon receipt of a low-pressure warning, 
would apply brakes and pull off the roadway. FMCSA stated: ``Low 
Pressure Warning--In most cases, you should notice an air leak or 
malfunction before getting a low-pressure warning; however, when a low-
pressure warning occurs, immediately bring the motorcoach to a safe 
stop, off of the roadway. Continuing to operate the motorcoach could 
result in an automatic application of the park brakes, possibly leading 
to a loss of control or a stop in an unsafe position.''
    5. DTNA is not aware of any accidents, injuries, owner complaints, 
or field reports related to this condition on the subject vehicles.
    6. DTNA also stated that NHTSA has previously granted petitions for 
decisions of inconsequential noncompliance for lighting requirements 
where technical noncompliance exists, but does not create a negative 
impact on safety:
    <bullet> In General Motors Corporation; Grant of Application for 
Decision of Inconsequential Noncompliance. 66 FR 32871 (June 18, 2001) 
a petition for inconsequentiality by General Motors Corporation was 
granted by NHTSA. In this instance, certain models could have 
unintended CHMSL illumination briefly if the hazard warning lamp switch 
is depressed to its limit of travel.
    <bullet> In General Motors, LLC, Grant of Petition for Decision of 
Inconsequential Noncompliance, a petition for inconsequentiality by 
General Motors, LLC (GM) was granted by NHTSA. See 83 FR 7847 (February 
22, 2018). In this instance, under certain conditions, the parking 
lamps on the subject vehicles fail to meet the requirement that parking 
lamps must be activated when headlamps are activated in a steady 
burning state.
    <bullet> In Grant of Application for Determination of 
Inconsequential Noncompliance with FMVSS No. 108, a petition for 
inconsequentiality by General Motors Corporation was granted by NHTSA. 
See 64 FR 48231 (September 2, 1999). In this instance, a certain model 
equipped with an electronic turn signal was affected by random inputs 
that cause the internal timing of the electronic circuit to become 
unsynchronized causing the left front turn signal lamp to flash at a 
rapid rate while the left rear turn signal lamp illuminates but does 
not flash. These conditions can continue after the turn signal lever 
automatically returns to the off position.
    7. DTNA believes that a technical noncompliance exists but does not 
create a negative impact on safety when the brake lamps illuminate 
during a brake system low air warning event. The stop lamp illumination 
serves to emphasize the message to following drivers that the vehicle 
is experiencing trouble and they should pay close attention. The Brake 
Air warning indicator light, on the driver's display panel, shows the 
driver that there is an issue with the air brake system. This would 
result in the driver bringing the vehicle to a safe stop and having the 
air system repaired before continuing.
    DTNA concluded by expressing its belief that the subject 
noncompliance is inconsequential as it relates to motor vehicle safety, 
and that 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.

VI. NHTSA's Analysis

    The burden of establishing the inconsequentiality of a failure to 
comply with a performance requirement in a standard--as opposed to a 
labeling requirement with no performance implications--is more 
substantial and difficult to meet. Accordingly, the Agency has not 
found many such noncompliances inconsequential.\1\ Potential 
performance failures of safety-critical equipment, like seat belts or 
air bags, are rarely deemed inconsequential.
---------------------------------------------------------------------------

Determination of Inconsequential Noncompliance, 69 FR 19897, 19899 
(Apr. 14, 2004) (citing prior cases where noncompliance was expected 
to be imperceptible, or nearly so, to vehicle occupants or 
approaching drivers).
---------------------------------------------------------------------------

    An important issue to consider in determining inconsequentiality is 
the safety risk to individuals who experience the type of event against 
which the recall would otherwise protect.\2\ In general, NHTSA does not 
consider the absence of complaints or injuries to show that the issue 
is inconsequential to safety. ``Most importantly, the absence of a 
complaint does not mean there have not been any safety issues, nor does 
it mean that there will not be safety issues in the future.'' \3\ 
``[T]he fact that in past reported cases good luck and swift reaction 
have prevented many serious injuries does not mean that good luck will 
continue to work.'' \4\

Inconsequential Noncompliance, 78 FR 35355 (June 12, 2013) (finding 
noncompliance had no effect on occupant safety because it had no 
effect on the proper operation of the occupant classification system 
and the correct deployment of an air bag); Osram Sylvania Prods. 
Inc.; Grant of Petition for Decision of Inconsequential 
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).

Inconsequential Noncompliance, 81 FR 21663, 21666 (Apr. 12, 2016).
    \4\ 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'').

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

[[Page 14327]]

    NHTSA has rejected petitions based on the assertion that only a 
small percentage of vehicles or items of equipment are likely to 
actually exhibit a noncompliance. The percentage of potential occupants 
that could be adversely affected by a noncompliance does not determine 
the question of inconsequentiality. Rather, the issue to consider is 
the consequence to an occupant who is exposed to the consequence of 
that noncompliance.\5\ These considerations are also relevant when 
considering whether a defect is inconsequential to motor vehicle 
safety.
---------------------------------------------------------------------------

    \5\ See Gen. Motors Corp.; Ruling on Petition for Determination 
of Inconsequential Noncompliance, 69 FR 19897, 19900 (Apr. 14, 
2004); Cosco Inc.; Denial of Application for Decision of 
Inconsequential Noncompliance, 64 FR 29408, 29409 (June 1, 1999).
---------------------------------------------------------------------------

    NHTSA notes that DTNA misquoted the decision language pertaining to 
a prior inconsequential noncompliance petition (83 FR 7847) by adding 
``The Agency agrees with GM that in this case'' prior to the original 
statement. NHTSA does not consider this addition accurate.
    The noncompliance, in the DTNA case currently being considered, is 
that the stop lamp illuminates when a braking system low air pressure 
warning indicator light is illuminated, regardless of whether the 
service brakes are applied.\6\ As the subject trucks have two air brake 
systems, which split the trailer brakes from the steer axle brakes, low 
air pressure will cause a brake application only if air pressure is 
lost in both systems. Should only one of the two air brake systems 
report low air pressure, the parking brakes would not engage but the 
stop lamps would illuminate in addition to the low air warning 
indicator light, which includes an audible alarm. The Agency believes 
that an alert would prompt the operator to safely pull over and/or 
attempt to slow/stop the truck soon after the warnings appear. In that 
case, the noncompliance would only result in a momentary illumination 
of the stop lamps without the brakes being applied.
---------------------------------------------------------------------------

    \6\ Per FMVSS No. 108, stop lamps should only be activated upon 
activation of the service brakes, or a device intended to retard the 
movement of the vehicle. See FMVSS No. 108, Table I-a.
---------------------------------------------------------------------------

    If the driver of a subject vehicle did not apply the brakes 
immediately after receiving a low air pressure warning, following 
drivers would be presented with a false indication that the subject 
truck was braking. Further, should there be an air leak, application of 
the service brakes will cause the air pressure to further drop, braking 
performance may be impacted, and it is also possible that the system 
will no longer be able to achieve proper pressure, which subsequently 
may cause the parking brakes to engage. As the function of a stop lamp 
is to notify other road users that a vehicle is stopping and/or slowing 
down, a vehicle equipped with an air braking system where the low air 
pressure warning on the instrument cluster along with an audible 
warning has been activated will likely prompt the driver to immediately 
pull over and/or attempt to slow/stop the vehicle.
    A previous NHTSA interpretation concerning trailer stop lamp 
illumination, requested by Wabash National Corporation, explained that 
the stop lamps were permitted to be illuminated in the event that the 
emergency braking system was activated when significant deceleration 
could occur.\7\ NHTSA does not agree with DTNA's argument that the 
activation of the stop lamps when the low air pressure warning occurs 
would be helpful for a warning other drivers of the brake malfunction. 
Nonetheless, NHTSA still believes this noncompliance would be 
inconsequential to safety. This is because when a vehicle with air 
brakes experiences a low-air event and notifies the driver of a brake 
system malfunction, NHTSA believes that the driver would likely respond 
by pulling over to the side of the road and taking the vehicle out of 
service until the brake system can be repaired. Because the act of 
pulling over to the side of the road would result in the intentional 
activation of the stop lamps and this sequence of events would likely 
occur only once before the vehicle is repaired, NHTSA believes that the 
activation of the brake lamps due to the low air pressure event would 
be inconsequential to safety.

VII. NHTSA's Decision

    In consideration of the foregoing, NHTSA finds that DTNA has met 
its burden of persuasion that the subject FMVSS No. 108 noncompliance 
in the affected trucks is inconsequential to motor vehicle safety. 
Accordingly, DTNA's petition is hereby granted and DTNA is consequently 
exempted from the obligation of providing notification of, and a free 
remedy for, that noncompliance under 49 U.S.C. 30118 and 30120.
    NHTSA notes that the statutory provisions (49 U.S.C. 30118(d) and 
30120(h)) that permit manufacturers to file petitions for a 
determination of inconsequentiality allow NHTSA to exempt manufacturers 
only from the duties found in sections 30118 and 30120, respectively, 
to notify owners, purchasers, and dealers of a defect or noncompliance 
and to remedy the defect or noncompliance. Therefore, this decision 
only applies to the subject trucks that DTNA no longer controlled at 
the time it determined that the noncompliance existed. However, the 
granting of this petition does not relieve truck distributors and 
dealers of the prohibitions on the sale, offer for sale, or 
introduction or delivery for introduction into interstate commerce of 
the noncompliant trucks under their control after DTNA notified them 
that the subject noncompliance existed.
