Highway Safety Programs; Model Specifications for Screening;
Devices to Measure Alcohol in Bodily Fluids

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

ACTION: Notice.

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

SUMMARY: This notice revises Model Specifications for Screening Devices
to Measure Alcohol in Bodily Fluids (Model Specifications) published in
the Federal Register on August 2, 1994 (59 FR 39382). These devices
test for the presence of alcohol using breath or bodily fluids such as
saliva. The Model Specifications support State laws that target
youthful offenders (i.e., ``zero tolerance'' laws) and the Department
of Transportation's regulations on Alcohol Misuse Prevention, and
encourage industry efforts to develop new technologies (e.g., non-
breath devices) that measure alcohol content from bodily fluids.
    This notice removed testing of Interpretive Screening Devices
(ISDs) and use of the Breath Alcohol Sample Simulator (BASS) device
from the Model Specifications. The ISDs did not provide an unambiguous
test result, as test results for ISDs are subjective and require
interpretation by a test administrator or technician. Because the
agency has determined the BASS device is not necessary for inclusion in
the Model Specifications, this notice removes all references to the
BASS device.
    Additionally, in order to ensure product integrity, this notice
provides guidelines for retesting devices when manufacturers
contemplate changes, revisions, or upgrades to alcohol screening
devices on the Conforming Products List (CPL).
    These revisions to the Model Specifications will not affect devices
currently listed on the CPL.

DATES: Effective Date: Revisions to these Model Specifications become
effective on March 31, 2008.

SUPPLEMENTARY INFORMATION:

I. Background

    As indicated in the Model Specifications published in 1994, the
agency will modify and improve the Model Specifications as new data and
test procedures become available and will alter the test procedures, as
necessary, to meet unique design features of specific devices. Since
publication of the Model Specifications, the agency encountered
difficulties ensuring the accuracy of testing ISDs and also determined
the use of the BASS is not necessary for inclusion in the Model
Specifications. These events made it necessary to revise the Model
Specifications.
    On December 14, 2007, (72 FR 71188), NHTSA proposed and sought
comments on amendments and revisions to the Model Specifications
published in 1994. In the notice, NHTSA explained that the 1994 Model
Specifications allowed for evaluation of screening devices that require
subjective interpretation of test results by a test administrator or
technician. These ISDs differ from devices that provide objective test
results, including the use of digital technology or the appearance of
lights or marks based on the presence or absence of alcohol. For
instance, use of pass/fail lights or enzymes that react with alcohol to
produce an unambiguous mark provide objective test results. Also, the
1994 Model Specifications required that interpretive devices be
evaluated subjectively under five lighting conditions (fluorescent,
incandescent, mercury, sodium and daylight) by a panel of ten novice
evaluators who are not color blind. Since publication of the 1994 Model
Specifications, NHTSA evaluated eight separate ISDs. Of those eight ISD
evaluations, none resulted in a successful outcome in the panel test
described above. In one evaluation, the device passed the test under
all lighting conditions except sodium. This device is no longer
manufactured. Although many novice evaluators were able to judge the
correct test outcome in the eight ISD evaluations, some could not, even
though the manufacturers' instructions were conveyed to the evaluators
and all evaluators passed tests to determine their color perception
ability. This subjective interpretation of test results does not ensure
accuracy and precision required to protect public safety. Due to
repeated problems in evaluating ISDs, NHTSA proposed to remove
altogether testing of ISDs and all references to interpretive or color
indicator tests from the Model Specifications.
    The 1994 Model Specifications provided for the use of the Breath
Alcohol Sample Simulator (BASS) device for delivering alcohol-in-air
test samples. The use of the BASS device is not necessary for inclusion
in the Model Specifications because the BASS device is intended for use
in testing the sampling efficiency of evidential breath testers. There
is no sampling efficiency test in the Model Specifications for alcohol
screening devices. The alcohol-in-air test sample for breath alcohol
screening devices is supplied by a calibrating unit. Therefore, the
agency proposed to remove all references to the BASS device from the
Model Specifications.
    The 1994 Model Specifications also provide procedures to conduct
special investigations and re-test a device if information gathered
indicates that a device listed on the CPL is not performing in
accordance with the Model Specifications. The agency proposed the
addition of Appendix B to provide guidance regarding notification and
re-testing when manufacturers contemplate revisions to devices listed
on the CPL. The proposed Appendix follows the language used in the
Model Specifications for evidential breath testing devices (58 FR
48705). Upon notification by a manufacturer of a contemplated change to
a device listed

[[Page 16957]]

on the CPL, NHTSA proposed that it would determine whether re-testing
is required. Such determination would look at several factors,
including the nature and reason for the change, the scope of the
change, the effects of the change on the performance of the device, and
how the change will be documented for the benefit of the user. NHTSA
would list device revisions and whether re-testing was required in the
next update to the CPL. Appendix B also would state that NHTSA may re-
test any device listed on the CPL at any time to determine continued
compliance and performance with the Model Specifications. A device
found not to perform in accordance with the Model Specifications would
be subject to the special investigation procedures discussed below.
    Having received no comments on any aspect of the agency's proposal,
this notice adopts the proposed revisions, including the ``Procedures''
and ``Model Specifications for Alcohol Screening Devices,'' without
change.

II. Procedures

    This section describes the current procedures. The DOT Volpe
National Transportation Systems Center (VNTSC), RTV-4F, Kendall Square,
Cambridge, MA 02142 tests products manufacturers submit to determine
whether the products meet the model specifications. Tests are conducted
semiannually, or as necessary. Manufacturers are required to apply to
NHTSA for a test date by writing to the Office of Behavioral Safety
Research, NTI-130, NHTSA, 1200 New Jersey Avenue, SE., Washington, DC
20590. At least 30 days are typically required from the date of
notification until the test can be scheduled.
    One week prior to the scheduled initiation of the test program,
manufacturers must deliver their devices to VNTSC. If the devices are
disposable, the manufacturer must deliver at least 300 such devices; if
the devices are reusable, the manufacturer need submit only a single
device. If a manufacturer of a reusable device wishes to submit a
duplicate, backup instrument, it may so do. The manufacturer is
responsible for ensuring that the devices operate properly and are
packaged correctly. The manufacturer must also deliver the operator's
manual (or instructions) and the maintenance manual (if any) that is to
be supplied with the purchase of the device, as well as specifications
and drawings fully describing the device and its use. Information
determined to be proprietary will be respected. (See 49 CFR Part 512,
regarding the procedure by which NHTSA will consider claims of
confidentiality.)
    In addition, the manufacturer must submit a self-certification,
certifying that the manufacturer meets the requirements according to
the U.S. Food and Drug Administration (FDA) Good Manufacturing
Practices regulations for devices used for medical purposes (21 CFR
Part 820), and that the device's label meets the requirements in FDA's
Labeling regulations for devices used for medical purposes (21 CFR Part
809.10), even if the devices are not to be used for medical purposes.
See Appendix A to this notice.
    The manufacturer has the right to check its device(s) between the
time of arrival at VNTSC and the start of the tests, but will have no
access to the device(s) during the tests. Any malfunction of a device
resulting in failure to complete any of the tests satisfactorily will
result in a determination that the device does not conform to the Model
Specifications. If a device is found not to conform to the Model
Specifications, it may be resubmitted for the next testing cycle after
appropriate corrections have been made. However, the agency reserves
the discretion to determine whether to conduct any retest.
    The agency intends to update and republish the CPL in the Federal
Register annually. Republications of the CPL add conforming alcohol
screening devices tested since the last CPL republication.
    NHTSA will continue to provide notification in the Federal Register
when the agency amends the Model Specifications as new data and test
procedures become available and will retest devices when necessary.
    The NHTSA Office of Behavioral Safety Research is the point of
contact for information about acceptance testing and field performance
of devices that are in the marketplace. NHTSA requests that users of
alcohol screening devices provide both acceptance and field performance
data to the Office of Behavioral Safety Research when such data
indicate potential performance problems. Information from users will
help NHTSA monitor whether alcohol screening devices are performing
according to the NHTSA Model Specifications.
    If information gathered indicates that a device on the CPL is not
performing in accordance with the Model Specifications, NHTSA may
direct VNTSC to conduct a special investigation. An investigation may
include visits to users and additional tests of devices obtained on the
open market. If the investigation indicates that a device actually sold
on the market does not meet the Model Specifications, the manufacturer
will be notified that the device may be removed from the CPL. In this
event, the manufacturer will have 30 days from the date of notification
to reply. Based on the VNTSC investigation and any data provided by the
manufacturer, NHTSA will decide whether the device should remain on the
CPL. If the device is removed from the CPL, the manufacturer will be
permitted to resubmit an improved device to VNTSC for testing when it
believes the problems causing its failure have been resolved. Upon
resubmission, the manufacturer must submit a statement describing what
has been done to overcome the problems that led to failure of the
device. The agency reserves the discretion to determine whether to
conduct any retest.
    If information gathered indicates that the manufacturer of a device
on the CPL does not comply with the requirements in FDA's Good
Manufacturing Practices regulations for devices used for medical
purposes or that the device's label does not comply with the
requirements in FDA's labeling regulations for devices used for medical
purposes, NHTSA may investigate the matter in consultation with FDA and
will notify the manufacturer that the device may be removed from the
CPL. The manufacturer will have 30 days from the date of notification
to reply. Based on any data provided by the manufacturer and
investigative findings, NHTSA will decide whether the device should
remain on the CPL. If the device is removed from the CPL, the
manufacturer will be permitted to resubmit a self-certification,
certifying that the manufacturer or its device complies with these FDA
requirements when it believes the problems causing its non-compliance
have been resolved. Upon resubmission, the manufacturer must submit a
statement describing what has been done to overcome the problems that
led to non-compliance.
    In accordance with the foregoing, the amendments of the Model
Specifications for Screening Devices to Measure Alcohol in Bodily
Fluids, are set forth below.

Appendix B--Guidelines for Re-testing of Modified Screening Devices
    Manufacturers contemplating revisions to an alcohol screening
device listed on the Conforming Products List (CPL) are advised that
the revision may affect the status of the device on the CPL. The
manufacturer should inform NHTSA of the contemplated change so that a
judgment can be made whether or not re-testing the revised alcohol
screening device is necessary. The following lists the type of
information NHTSA uses in determining the necessity to re-test an
alcohol screening device, and is provided as guidance to manufacturers:
     Manufacturer and Model Name.
     Nature and reason for change(s).
     Scope of change(s) (e.g., Will existing devices be
retrofitted? Will the change apply to some users but not others?)
     Will the change(s) affect performance of the device with
regard to the Model Specifications? (Precision and accuracy, blank
reading, temperature operations, or vibrations.)
     How will the change(s) be documented for the benefit of
the user? (e.g., Will the change(s) be documented in service bulletins
and/or service manuals? If not, why not?)
    If necessary for clarity, drawings of the listed and changed device
may also be helpful in NHTSA's deliberations.
    If, upon review of information provided by a manufacturer, it is
determined that re-testing is not warranted, a statement to that effect
will be included in the next scheduled CPL update.
    NHTSA reserves the right to test any CPL-listed device on the open
market to determine continued compliance and performance in accordance
with these Model Specifications. Devices found not to comply with or
perform in accordance with the Model Specifications are subject to the
investigation provisions stated above in section II, Procedures.
