National Highway Traffic Safety Administration
49 CFR Part 571
Denial of Petition for Rulemaking; Federal Motor Vehicle Safety
Standards
AGENCY: National Highway Traffic Safety Administration (NHTSA),
Department of Transportation.
ACTION: Denial of petition for rulemaking.
-----------------------------------------------------------------------
SUMMARY: This document denies a petition from Mr. Charles Smyth for
rulemaking to require the use of Daytime Running Lights (DRLs) on all
vehicles in America. The agency does not have the authority to require
retrofitting of vehicles in use, and the issue of mandatory DRLs on new
motor vehicles has been considered by the agency on numerous occasions
and is still under consideration. Federal Motor Vehicle Safety Standard
No. 108; ``Lamps, Reflective Devices and Associated Equipment,'' was
amended in 1993 to permit new vehicles to be equipped with DRLs and to
assure that if used, they cause no safety problems. Canada mandated
DRLs on all new passenger cars, multipurpose vehicles, buses and trucks
manufactured for sale after December 1, 1989. General Motors (GM),
SAAB, Volvo, and Volkswagen have begun to market DRL equipped vehicles
in the United States (U.S.). NHTSA is monitoring Canadian U.S. crash
data to evaluate the benefit of DRL use in the U.S. Should the safety
experience demonstrate that DRLs are cost-effective safety devices,
NHTSA would consider mandating them.
FOR FURTHER INFORMATION CONTACT: Mr. Jere Medlin, Office of Rulemaking,
NHTSA, 400 Seventh Street SW., Washington, DC 20590. Mr. Medlin's
telephone numbers are: (202) 366-5276; FAX (202) 366-4329.
SUPPLEMENTARY INFORMATION: By a letter dated February 17, 1995, Mr.
Charles Smyth petitioned the agency to require the use of DRLs on all
cars in America. Mr. Smyth stated that SAAB cars have had DRLs since
1968 and that Sweden made them mandatory in 1977. He also stated that
Volvo had made DRLs standard on its 1995 cars. Mr. Smyth stated that
Transport Canada had just completed a study that showed an 8.3%
reduction of two-vehicle, opposing-direction, daytime collisions by
comparing the crash experience of vehicle model years before and after
the DRL legislation (mandate) in Canada. Mr. Smyth claims other studies
have shown reductions in crashes among vehicles where DRLs have been
used and that the growing support for DRLs is overwhelming. However,
Mr. Smyth did not provide any analysis of the potential benefits of
DRLs in U.S. driving situations in his petition nor did he consider the
cost to the public of such a decision.
NHTSA has investigated the use of ``lamps on'' to improve highway
safety. The use of DRLs, headlamps or other lamps on the front of the
vehicle during the daytime makes vehicles more visible. NHTSA has
tested DRLs, in white and amber colors, with intensities ranging from
as bright as turn signal lamps to brighter than lower beam headlamps.
These lamps operate automatically with the ignition switch, with no
other lamps being illuminated. NHTSA has carefully analyzed DRL studies
from around the world for the effectiveness of automotive DRLs in
reducing crashes. The agency has not yet found any studies that have
shown conclusively that DRLs would be effective in reducing the number
of crashes in the U.S.
A 1990 study by the Netherlands TNO Institute for Perception titled
``Daytime Running Lights: A Review of Theoritical Issues and Evaluation
Studies'' concluded that there is no unequivocal evidence of an effect
of DRL on accident rates. Most of these former DRL studies had
statistical or methodological shortcomings such that their value to
NHTSA in evaluating DRL use in the U.S. was limited. Michael Perel
reviewed previous DRL studies in ``Evaluation of the Conspicuity of
Daytime Running Lights,'' Auto & Traffic Safety, Summer 1991, Vol. 1
No. 1, National Highway Traffic Safety Administration Document No. DOT-
HS-807-755. Perel found that flaws such as collecting data only during
twilight-viewing conditions, too few subjects for statistical validity,
unintended bias introduced by failure to randomize DRL application
between study groups, comparing non-comparable groups, and subjective
measurement/observer bias influences, existed in these studies. Perel
noted that the Netherlands postponed a planned regulation of DRLs
because of criticism of past studies. Additionally, Perel stated that
whether flawed or not, many
[[Page 35374]]
of the studies were limited because of their low relevance to the U.S.
regarding the driving environment, including ambient light level
differences, greater proportions of pedestrian and cyclist crashes in
the study countries, and effects voluntary usage.
NHTSA has received the Transport Canada DRL report and the agency
is still analyzing it. It provides a positive look at a narrow range of
crashes that are susceptible to the DRL solution. More information is
expected from Canada which will provide a view of DRL effect on all
types of crashes. When recieved, it may provide a valuable resource for
determining the value of DRLs in the U.S.
Because NHTSA has not yet been able to show a national safety
benefit from the use of DRLs, a regulation mandating the installation
and activation of any type of daytime lamp is not appropriate at this
time. The agency does know, however, that DRLs improve a vehicle's
frontal conspicuity in low to moderate ambient daylight illumination
typical of more northern latitudes than those of the U.S. In 1990, GM
petitioned the agency to change the lighting safety standards to
explicitly permit but not mandate DRLs. As a result of GM's petition,
Standard No. 108 was changed to permit certain kinds of DRLs which do
not exhibit disbeneficial performance such as turn signal masking or
glare in mirrors. GM has decided to provide DRLs on the 1995 Geo Metro,
Chevrolet S10 pickup and the Corsica and Beretta intended for the U.S.
market and plans to increase model coverage over the next few years.
VW's Jetta III, Golf III and GTI car lines also have DRLs as standard
equipment. SAAB and Volvo have DRLs available, but installation and use
are optional depending on the models. The agency hopes to be able to
monitor the safety experience of those vehicles with full model year
DRLs installations to determine whether the mandatory installation and
activation of DRLs in the U.S. would be cost beneficial to the public.
In evaluating whether to mandate DRLs, the agency must consider
both potential benefits and costs. The costs of mandatory installation
and activation of DRLs would be decreased fuel economy and increased
vehicle purchase cost from the added wiring and switching devices.
Additionally, depending on the manner in which the DRLs are
implemented, headlamp burnout could increase. The benefits could
include a decrease in the number of crashes, with accompanying
reductions in casualties and crash repair costs. While the agency
continues its analysis of this issue, it is inappropriate to commence a
rulemaking proceeding. Should the analysis indicate significant safety
benefits at a reasonable cost, the agency could initiate rulemaking at
that time.
In accordance with 49 CFR part 552, this completes the agency's
technical review of the petition. The agency has concluded that there
is no reasonable possibility that the amendment requested by the
petitioner would be issued at the conclusion of the rulemaking
proceeding undertaken at this time. Accordingly, it denies Mr. Smyth's
petition.
