Abstract

In compliance with the Paperwork Reduction Act of 1995 (PRA), this notice announces that the Information Collection Request (ICR) summarized below will be submitted to the Office of Management and Budget (OMB) for review and approval. This document describes a new collection of information for which NHTSA intends to seek OMB approval titled "Pulsating Stop Lamps, Flashing Lights, and Distance Perception." A Federal Register Notice with a 60-day comment period soliciting comments on this information collection was published on May 26, 2026. Three comments were received in response, providing support for the research and recommending consideration for motorcycles and international regulations related to "emergency stop signals." While these topics are out of scope for this research, NHTSA plans to incorporate the recommended topics into the final report by including them in the literature review and background sections. Incorporation of these inputs into the study does not materially impact the burden on the participants, and therefore the participant burden estimate included in the 60-day notice remains unchanged.

SUMMARY: In compliance with the Paperwork Reduction Act of 1995 (PRA), 
this notice announces that the Information Collection Request (ICR) 
summarized below will be submitted to the Office of Management and 
Budget (OMB) for review and approval. This document describes a new 
collection of information for which NHTSA intends to seek OMB approval 
titled ``Pulsating Stop Lamps, Flashing Lights, and Distance 
Perception.'' A Federal Register Notice with a 60-day comment period 
soliciting comments on this information collection was published on May 
26, 2026. Three comments were received in response, providing support 
for the research and recommending consideration for motorcycles and 
international regulations related to ``emergency stop signals.'' While 
these topics are out of scope for this research, NHTSA plans to 
incorporate the recommended topics into the final report by including 
them in the literature review and background sections. Incorporation of 
these inputs into the study does not materially impact the burden on 
the participants, and therefore the participant burden estimate 
included in the 60-day notice remains unchanged.

    Type of Request: New information collection.
    Type of Review Requested: Regular.
    Length of Approval Requested: Three years from date of approval.
    Summary of the Collection of Information: The National Highway 
Traffic Safety Administration (NHTSA) is seeking approval to conduct 21 
voluntary information collections as part of a multi-phase research 
study involving up to 270 licensed drivers of various ages to evaluate 
potential safety benefits and disbenefits of implementing pulsating 
stop lamps on a broader scale across a range of driving contexts and 
over time. The study involves three different parts that will be 
executed simultaneously:
    Descriptions of the VTTI (Part 1--Test Track Study) and UMN (Part 
2--Survey Research and Part 3--Simulator Study) efforts are detailed 
below.
    <bullet> Part 1--Test Track Study: The data collection will consist 
of one driving session with an instrumented vehicle. A group of 
volunteer participants, each with a valid driving license, will be 
recruited by VTTI to participate in the study. The participants will 
drive the instrumented vehicle through controlled driving tests on the 
Smart Roads facilities (controlled-access test tracks built to Federal 
Highway Administration standards). The focus is to characterize how 
pulsating stop lamps affect driver distance perception and time-to-
collision judgements under a range of situations with multiple lead 
vehicles and braking signal types (i.e., steady-burn and flashing). 
Visual distraction associated with flashing lights will also be 
assessed by tracking the driver's gaze. Following the presentation of 
all the testing conditions, participants will provide feedback about 
the stop lamp configurations. The entirety of participation in the 
study is estimated at three hours.
    <bullet> Part 2--Survey Research: The data collection will consist 
of one online survey. Participants will join the study through a 
crowdsourced research website and will be directed to the University of 
Minnesota's <a href="http://Qualtrics.com">Qualtrics.com</a> survey site using their personal computer. 
Participants will be shown a series of animated videos of car-following 
scenarios with various stop lamp configurations. For each video, 
participants will be asked to provide subjective feedback, including 
their interpretation of each stop lamp configuration and their expected 
driving response to each scenario. The goal of this collection is to 
characterize driver's understanding and interpretation of pulsating 
stop lamps. The entirety of participation in the study is estimated at 
0.5 hours.
    <bullet> Part 3--Simulator Study: The data collection will consist 
of three simulated driving sessions. A group of volunteer participants, 
each with a valid driving license, will be recruited by UMN to 
participate in the study. The driving simulation study aims to address 
a number of research questions relating to the driver response 
characteristics in response to flashing or pulsating stop lamps during 
normal and crash imminent scenarios. In addition, the multi-session 
experiment aims to address questions regarding the effects of repeated 
exposure to flashing or pulsating stop lamps over time.
    Across three sessions, participants will be asked to complete a 
series of drives in an immersive driving simulator while following 
vehicles with varied stop lamp configurations and braking events. In 
addition to participant's brake response characteristics collected from 
the simulator, participants' demographics, attitudes and 
interpretations will also be measured with questionnaires.
    The driving simulation study aims to quantify driver performance in 
response to pulsating stop lamps during normal and crash imminent 
scenarios. In addition, the multi-session experiment aims to address 
questions regarding the effects of repeated exposure to pulsating stop 
lamps over time. The entirety of participation in the study is 
estimated at 3.5 hours.
    NHTSA will use the information gathered from both the VTTI and UMN 
efforts to produce a technical report that presents the results of the 
study. The report will provide important information needed by NHTSA to 
develop, implement, and maintain effective countermeasures that meet 
the agency's mandate to reduce the number of deaths, injuries, and 
economic losses resulting from motor vehicle crashes on the U.S. 
highways.
    Recruitment of study respondents will be from the area near the 
testing facilities in Blacksburg, VA, Minneapolis, MN, as well as a 
digital crowdsourcing component. The target for the study varies based 
on the part in question (a total of 30 participants for Part 1, a total 
of 200 participants for Part 2, a total of 40 participants for Part 3); 
however, the research team has provided sufficient additional 
recruitment such that the target sample is achieved given expected 
reductions in respondents due to ineligibility and attrition. The 
planned data collection activities discussed herein have been approved 
by an Institutional Review Board.
    Description of the Need for the Information and Proposed Use of the 
Information: As part of NHTSA's mission to save lives, prevent 
injuries, and reduce traffic-related health care and other economic 
costs, the agency conducts research as a foundation for the development 
of motor vehicle standards and traffic safety programs The House Report 
accompanying the

[[Page 55665]]

Departments of Transportation, and Housing and Urban Development, and 
Related Agencies Appropriations Bill, 2020 (H.R. 116-106) directed 
NHTSA to study the safety effectiveness of rear-end collision avoidance 
systems that mitigate and prevent rear-end crashes and specified that 
the study should include the effectiveness of pulsating light systems 
in motor vehicles.
    Pulsating stop lamps are not currently permitted on new vehicles 
under the Federal Motor Vehicle Safety Standard (FMVSS) No. 108, which 
requires stop lamps to be steady burning (FMVSS No. 108 S7.3). However, 
there are aftermarket products which alter stop lamps so that they 
pulsate when the brake is applied. NHTSA has previously conducted 
research studying the potential of flashing rear-brake lighting to 
capture attention in crash-imminent scenarios. However, there may be 
unintended consequences associated with pulsating stop lamps when 
considering the broader driving context in which they operate.
    The objective of this NHTSA project is to evaluate potential safety 
benefits and disbenefits of implementing pulsating stop lamps on a 
broader scale across a range of driving contexts and over time.
    NHTSA will use the information collected to produce a technical 
report containing summary statistics and tables that will be made 
available publicly through the agency website and the National 
Transportation Library.
    60-Day Notice: A Federal Register notice with a 60-day comment 
period soliciting public comments on the following information 
collection was published on May 26, 2026 (91 FR 30783). NHTSA received 
a total of three public comments from the American Trucking 
Associations (ATA), the Motorcycle Industry Council (MIC), and the 
Alliance for Automotive Innovation (the Alliance).
    The ATA supported the proposed research, citing the importance of 
understanding the safety impacts of pulsating stop lamps and pulsating 
auxiliary lamps on commercial trucks.
    The MIC indicated they support the overall goal of the research and 
requested that NHTSA include motorcycles as part of the study, noting 
that motorcycles have a narrower profile than other motor vehicles and 
may benefit from pulsating stop lamps. MIC further encouraged any 
research on motorcycles to explore the use of pulsating stop lamps 
combined with hazard lamps, and increased illumination levels above 
current legal limits. NHTSA agrees that the narrower profile of a 
motorcycle may affect the safety impacts of pulsating stop lamps. While 
the scope of the proposed research is limited to aftermarket flashing 
or pulsating brake light systems for passenger vehicles and commercial 
trucks, NHTSA will conduct a review of literature related to pulsating 
stop lamps on motorcycles, the combined use of stop lamps and hazard 
lamps, and the effect of pulsating lamp brightness, and will 
incorporate the findings of the literature review into the study's 
final report, noting the potential for future research.
    The Alliance supported the proposed research, and encouraged NHTSA 
to consider relevant international approaches, including requirements 
for ``emergency stop signals'' under UNECE Regulation No. 48. NHTSA 
acknowledges that prior work sponsored by the agency and supported by 
industry has emphasized the use of flashing brake signals as a means of 
alerting drivers to emergency braking events (Wierwille et al., 2005; 
\1\ Wierwille et al., 2009; \2\ Llaneras et al., 2010).\3\ Unlike 
``emergency stop signals'' supported by UNECE that trigger under hard 
deceleration, the scope of the proposed research is focused on 
aftermarket systems in the U.S. that activate on any brake pedal press, 
regardless of deceleration rate or brake pedal force. To incorporate 
the point raised in this comment, discussion of international 
regulations and previous research on emergency brake signaling will be 
included in the background section of this project's final report, and 
the potential for future research will be noted.

    After thoughtful consideration of the comments, NHTSA will 
incorporate discussion of the application of this research to 
motorcycles as well as considerations for alternative brake signal 
configurations (e.g., emergency stop signals) in the final report. 
Incorporation of the above material into the study does not materially 
impact the burden on the participants, and therefore the participant 
burden estimate included in the 60-day notice remains unchanged.
    Affected Public: Respondents to this collection will be members of 
the public recruited from Blacksburg, VA; Minneapolis, MN, and national 
sample. Effort will be made to recruit equal numbers of adult males and 
females, including participants aged 21 to 65. A representative sample 
is not necessary to satisfy the objectives of the study and therefore, 
a convenience sample of individuals meeting eligibility criteria will 
be sufficient.
    Estimated Number of Respondents: The target for the study is for 
270 participants total across all 3 parts of the study (a total of 30 
participants for Part 1, a total of 200 participants for Part 2, a 
total of 40 participants for Part 3) to complete all sessions with 
valid data collected for each. However, eligibility and attrition must 
be accounted for throughout the individual information collections 
included in this request. As previously stated, there are 21 individual 
information collections in this request. The number of respondents 
annually for each collection is as follows: Recruitment Screener--33; 
Participant Reminders--10; Informed Consent--10; W-9 Form--10; Vision-
Hearing Form--10; Surface Street Controlled Driving on Smart Roads--10; 
Highway Controlled Driving on Smart Roads--10; Post-Drive 
Questionnaire--10; Survey Research--67; One-time Pre-Questionnaire--67; 
Survey Research Data Collection and Driver Response--67; One-time Post-
Questionnaire--67; Simulator Study Screening Questionnaire--40; 
Participant Scheduling--13; Informed Consent--13; Vision Evaluation--
13; Pre-Simulator Questionnaire--13; Driving Simulation Checklist--13; 
Post-Simulator Drive Questionnaire--13; Demographics Questionnaire--13; 
and Post-Simulator Study Questionnaire--13.
    Frequency: This is a one-time information collection.
    Estimated Number of Responses: 12,470.
    Estimated Annual Burden Hours: The total estimated burden for this 
one-time information collection is 386 hours total, or 127 annual 
burden hours (based on a 3-year period of performance). Further details 
are provided below. This ICR includes 21 information collections (8 
information collections at VTTI and 13 at UMN), which are described 
below. Total burden estimates for each information collection are 
provided in Table 1 and annual burden estimates for each information 
collection are provided in Table 2.

[[Page 55666]]

Part 1--Test Track Study

1. Recruitment Screener (Form 2150)

    An estimated 100 total respondents (33 respondents annually) will 
answer a Recruitment Screener (form 2150) over the phone to determine 
if they qualify for the study. Participants will be screened over the 
phone to determine eligibility, with recruitment personnel recording 
responses on a paper form using an anonymized ID. Respondents who meet 
the inclusion criteria will be individually scheduled for an 
appointment over the phone to go to the contractor facilities in 
Blacksburg, VA. Respondents are expected to take an estimated average 
of 20 minutes to complete the questionnaire and will complete this 
questionnaire once, resulting in a total of 33 burden hours (11 annual 
burden hours) for the screening of potential participants. Recruitment 
of study respondents is from Southwest Virginia, specifically the New 
River Valley and surrounding areas (Roanoke, Salem, etc.).

2. Participant Reminders (Form 2151)

    Participants will both be contacted by phone in order to remind 
them of their appointment (Form 2151), as well as contacted through 
email (Form 2151). These activities (the phone contact and the 
participant reviewing the email content) are expected to take a total 
of two minutes. For a maximum of 30 participants (10 respondents 
annually), this results in a total of 1 burden hour (<1 annual burden 
hour).

3. Informed Consent (Form 2152)

    Based on an estimate that 30 percent of those who begin the 
screening process will be eligible and interested in participating, we 
anticipate an estimated 30 total participants (10 respondents annually) 
initiate the consenting process. The visit to the VTTI facility will 
begin with a consenting process that includes an overview of the study, 
an explanation of the informed consent form, (Form 2152) and an 
opportunity for the potential participants to ask questions and get 
clarification. Those individuals who consent to the study and enroll 
will complete the Informed Consent form and move on to the next 
process. This consent process and completion of the Informed Consent 
form, using the maximum of 30 respondents (10 annually), are expected 
to take six minutes and will be completed resulting in a total of three 
burden hours (1 annual burden hour). This is a paper form, which 
participants are required to sign two copies of, keeping one for their 
records.

4. W-9 Form

    After completing the informed consent process, 30 participants will 
also be required to fill out a W-9 Form, in order to receive 
compensation for their participation. This form is expected to take two 
minutes and will be completed once, resulting in a total of 1 burden 
hour (<1 annual burden hour). This is a paper form.

5. Vision-Hearing Form (Form 2153)

    Following the consenting process, the experimenter will administer 
a brief vision and hearing evaluation (Form 2153) for a maximum of 30 
respondents (10 respondents annually). The purpose of this evaluation 
is to ensure that participants meet the basic vision requirements of 
driver's licensure in Virginia (20/40), and to confirm that they can 
hear instructions provided by the experimenter when looking away. The 
hearing evaluation consists of repeating approximately five statements 
back to the experimenter. Results will be completed once and will be 
recorded on paper. This evaluation is expected to take two minutes, 
resulting in a total of 1 total burden hour (<1 annual burden hour).

6. Surface Street: Controlled Driving on Smart Roads (Form 2154)

    To assess reactions to multiple brake light configurations and 
scenarios, study participants will experience a series of controlled 
driving tests with research vehicle on the Smart Roads Surface Street 
test track. VTTI anticipates that staged trial scenarios on the Surface 
Street test track will include 3-lanes of forward traffic (a lead, and 
two adjacent vehicles on either side of the lead). Participants will be 
presented with a set of staged car-following trials in which they must 
respond to lead vehicle braking events. To ensure safety, VTTI will use 
a dual-control study vehicle that has been specifically modified by 
moving the primary driving controls to the rear seat (experimenter 
station) while still maintaining functional driving capabilities from 
the factory driver's seat. The modifications allow the experimenter in 
the rear seat to take control of the vehicle at any time, but still 
provides the ability to measure driver control inputs in response to 
staged braking events. Participant drivers will be required to brake as 
needed and appropriate when they first detect lead vehicle 
deceleration. Visual occlusion will be used to control the onset of the 
exposure interval and mimic a distracted driver, with the drivers' 
``gaze'' opening just prior to the start of the trial. Note that the 
participant's braking response, deceleration profile, and gaze pattern 
will serve as key outcome measures during these trials. Not including 
the questionnaire elements referenced below, this driving session is 
expected to take 130 minutes, including vehicle familiarization, drive-
time, and breaks. For a maximum of 30 participants (10 respondents 
annually), this results in a total of 65 burden hours (22 annual burden 
hours).

7. Highway: Controlled Driving on Smart Roads (Form 2155)

    The highway portion of the data collection investigates the impact 
of pulsating/flashing lights on driver brake response characteristics 
and habituation resulting from repeated exposures. This part of the 
study will use the Smart Roads Highway section allowing continuous 
driving interactions and evolving events over a 35-minute period. As 
with the Surface Street portion, VTTI will use a dual-control study 
vehicle that has been specifically modified by moving the primary 
driving controls to the rear seat (experimenter station) while still 
maintaining functional driving capabilities from the factory driver's 
seat. Unlike the Surface Street portion, participants will be actively 
driving the vehicle with the rear-seat experimenter serving as a safety 
driver intervening to take control of the vehicle if needed. Specific 
aspects of focus during this portion include car following, headway 
maintenance, and braking scenarios under distracted and attentive 
driving, extended car following situations (over a period of minutes, 
habituation to flashing/pulsating signals over a single episode where 
pulsing/flashing signals are de-coupled from meaningful deceleration 
events (episodic habituation). This driving session is expected to take 
35 minutes, including vehicle familiarization, drive-time, and breaks. 
For a maximum of 30 participants (10 respondents annually), this 
results in a total of 18 burden hours (six annual burden hours).

8. Post-Drive Questionnaire (Form 2156)

    Following the Highway portion of the VTTI test track scenarios, 
respondents will be asked to complete a single Questionnaire (on paper) 
(Form 2156) related to their reactions to the brake light presentation. 
Completion of this form will take five minutes per person and is to be 
completed 1 time per respondent for a maximum of 30 respondents (10 
respondents annually), resulting in a total of three burden hours (one 
annual burden hour).

[[Page 55667]]

Part 2--Survey Research

1. Informed Consent (Form 2157)

    An estimated 200 participants (67 respondents annually) will be 
recruited via <a href="http://prolific.com">prolific.com</a> and initiate the consenting process. Using 
the maximum 200 respondents (six annually), the consent process, 
including reading the information sheet and agreeing to participate, is 
expected to take five minutes and will be completed 1 time per 
respondent, resulting in a total of 17 burden hours (six annual burden 
hours). This is a digital form, which participants digitally indicate 
their agreement and consent and are then free to download a copy for 
their records.

2. One-Time Pre-Questionnaires (Form 2158)

    After the informed consent process, respondents will complete a 
series of online forms filled on Prolific, comprising a demographics 
questionnaire and a request to participants to provide their Prolific 
ID's to allow the research team to validate responses and provide 
payment via Prolific payment system. Respondents are expected to take 
an estimated average of one minute to complete the one-time 
questionnaires and will complete this questionnaire once. This data 
collection, using the maximum of 200 respondents (67 annually), results 
in a total of three burden hours (one annual burden hour) for 
participants.

3. Survey Research Data Collection and Driver Response (Form 2159)

    Participants using an online crowdsourcing platform (<a href="http://prolific.com">prolific.com</a>) 
will then observe a series of animated images in an imagined vehicle-
following scenario and respond with their interpretations of the 
behavior of the vehicle in the animated image, as well as their likely 
responses in the vehicle-following scenario. 54 experimental trials 
will be presented in random order. Each video will play for six 
seconds. Along with each video, participants will be asked to answer 
questions related to potential signal interpretations, potential 
driving responses, and subjective ratings. Using the maximum of 200 
respondents (67 annually), each trial (viewing the video and responding 
to the associated survey questions) is anticipated to take no more than 
0.5 minutes and will be completed 54 times per respondent, resulting in 
a total of 90 burden hours (30 annual burden hours).

4. One-time Post-Questionnaires (Form 2160)

    A post-study questionnaire is included at the end of the study, 
which is a set of three questions asking about their experience with 
pulsating or flashing brake lights, requiring a response on multiple 
choice entries. Respondents are expected to take an estimated average 
of one minute to complete the one-time questionnaires and will complete 
this questionnaire once. This data collection, using the maximum of 200 
respondents (67 annually), results in a total of three burden hours 
(one annual burden hours) for participants.

Part 3--Simulator Study

1. Screening Questionnaire (Form 2161)

    An estimated 120 participants (40 respondents annually) will 
complete a screening questionnaire to determine study eligibility. 
Respondents are expected to take an estimated average of three minutes 
to complete the questionnaire and will complete this questionnaire 1 
time per respondent, resulting in a total of six burden hours (two 
annual burden hours).

2. Participant Scheduling (Form 2162)

    Participants who pass the screening are potential candidates for 
scheduling. Participants must be at least 18 years of age, have a 
driver's license for at least one year, have adequate visual acuity and 
normal color vision and hearing, and not have conditions that leave 
them susceptible to simulation sickness (e.g., issues with dizziness, 
motion sickness, sea sickness, migraines, etc.). There will also be 
natural attrition from participants who lose interest after they've 
filled out the screening form. This will restrict the number of 
participants who are eligible for scheduling, from 120 who complete the 
screening survey to those who are scheduled and take the consent form 
in the next line item. For scheduling participants for the first 
simulator driving session, along with the informed consent and vision 
evaluation, the research team will reach out to the participant with 
their preferred method (e.g., email or phone), and coordinate the best 
available time for both the research team and the participant. 
Participant Scheduling for First Session, using the maximum of 40 
respondents (13 annually), is expected to take two minutes and will be 
completed three times per respondent resulting in a total of four 
burden hours (one annual burden hour).

3. Informed Consent (Form 2163)

    While NHTSA estimates that 120 respondents will begin the screening 
process, NHTSA estimates that only 40 (13 respondents annually) will 
complete informed consent, anticipating that either some respondents 
may choose not to proceed with the study or that the experimenter may 
determine that they should not participate (uncooperative, impaired, 
etc.). The visit to the UMN facility will begin with a consenting 
process that includes an overview of the study, an explanation of the 
consent form, and an opportunity for the potential participants to ask 
questions and get clarification. Those individuals who consent to the 
study and enroll will complete the Informed Consent form (Form 2163) 
and move on to the next process. This consent process and completion of 
the Informed Consent form, using the maximum of 40 respondents (13 
annually), are expected to take five minutes and will be completed one 
time per respondent, resulting in a total of three burden hours (one 
annual burden hour). This is a digital form, which participants are 
required to sign digitally and are able to download a copy if desired.

4. Vision Evaluation (Form 2164)

    In order to ensure that the participants in the study have 
comparable visual capabilities, they will be evaluated on their visual 
acuity and color vision, due to the UMN simulator study having 
significant visual requirements. The evaluation will comprise a 
combination of the typical Snellen test for visual acuity, as well as 
Ishihara's Concise Color Vision Test. The former requires participants 
to read rows of letters in progressively smaller font sizes, and the 
latter requires participants to identify numbers and lines in colored 
plates. This vision evaluation, using the maximum of 40 respondents (13 
annually), is expected to take 10 minutes and will be completed one 
time per respondent, resulting in a total of seven burden hours (two 
annual burden hours).

5. Pre-Simulator Questionnaire (Form 2165)

    Before the simulation drive, participants are administered the pre-
drive Short Stress State Questionnaire (SSSQ), which assesses the 
change in task stress experienced by the participant during the 
simulator drive. This Pre-Simulator Questionnaire, using the maximum of 
40 respondents (13 annually), is expected to take two minutes and will 
be completed three times per respondent, resulting in a total of four 
burden hours (one annual burden hour).

6. Driving Simulation Checklist (Form 2166)

    The simulated world will consist of a roughly 10-mile stretch of a 
four-lane or six-lane divided highway at dusk or nighttime conditions, 
i.e., to maximize the visibility of brake lamp indications in the 
projection system-based simulation environment. Participants will be 
presented with a brief urban driving scenario featuring a series of 
city blocks and signalized intersections. Participants will be given an 
indication of which lane they should travel in and, depending on beta 
and pilot testing results, may be prompted to reach a set speed and set 
their cruise control to maintain this speed. Distractor and target 
vehicles will be presented in the roadway and will be programmed to 
travel at an independent speed or a speed which maintains a constant 
distance from the participant's vehicle. Participants are expected to 
perform four 10-mile drives during each test session. The Simulator 
Driving Session 1, using the maximum of 40 respondents (13 annually), 
is expected to take 50 minutes and will be completed three times per 
respondent, resulting in a total of 100 burden hours (33 annual burden 
hours).

7. Post-Simulator Drive Questionnaire (Form 2167)

    After completing the four drives, participants will complete the 
Post-Simulator Drive Questionnaire (Form 2167. This includes a set of 
questions assessing respondents' understanding of the meaning of the 
flashing brake lamps, along with the sense of urgency, usefulness, ease 
of interpretation, and annoyingness, distractingness, and discomfort of 
the brake lamps in the driving scenario. Other questions include Rating 
Scale Mental Effort (RSME) and the post-drive version of the Short 
Stress State Questionnaire (SSSQ). The RSME assesses how mentally 
demanding the drive was for the participant, and the SSSQ assesses the 
change in task stress experienced by the participant during the 
simulator drive by measuring the participant's self-reported stress 
before (Pre-Questionnaire) and immediately after (Post-Questionnaire) 
the drive. The Post-Stimulator questionnaire also has a set of 
questions examining symptoms of simulation sickness (Wellness 
Questionnaire), to ensure the health and well-being of participants 
after the drive. This set of questionnaires, using the maximum of 40 
respondents (13 annually), is expected to take 10 minutes and will be 
completed three times per respondent, resulting in a total of 20 burden 
hours (seven annual burden hours).

8. Demographics Questionnaire (Form 2168)

    After the first set of drives, a set of questionnaires is 
administered, which includes demographic questions asking about age, 
sex, education level, racial background, region of habitation (urban, 
suburban, rural), and area the participant drives. This set of 
questionnaires, using the maximum of 40 respondents (13 annually), is 
expected to take one minute and will be completed one time per 
respondent, resulting in a total of one burden hour (0.43 annual burden 
hours).

9. Post-Simulator Study Questionnaire (Form 2169)

    After completing all three simulation sessions, participants will 
complete the post-simulator study questionnaire. These include 
questions about participant experience with pulsating brake lights and 
whether they've encountered, driven, or owned a vehicle with pulsating 
brake lights. This will also include a brief debriefing period where 
the participant will verbally communicate their experiences with the 
simulated drives. The Post-Simulator Study Questionnaire, using the 
maximum of 40 respondents (13 annually), is expected to take five 
minutes and will be completed once per respondent, resulting in a total 
of three burden hours (one annual burden hour).
    For ease in understanding the calculations for burden and 
opportunity cost, Tables 1, 2, and 3 summarize the estimated annual 
burden hours for each of the study-related activities and forms, based 
on a 3-year period. Note: For Tables 1-3, Annual Number of Respondents 
is rounded to the nearest 1, Cost per Response is rounded to the 
nearest $.01, Annual Burden Hours are rounded to the nearest hour, 
Annual Opportunity Cost is rounded to the nearest $1, and Loaded Annual 
Opportunity Cost is rounded to the nearest $1. There may be some 
discrepancies in the tables due to rounding. The annual information 
will be entered into ROCIS.
