FHWA Worker Visibility Rule
23 CFR 634
SAFETEA–LU, Section 1402:
Worker Injury Prevention and Free Flow of
Vehicular Traffic
Worker Visibility Rule (23 CFR 634):
Required FHWA to issue regulations to decrease the
likelihood of worker injury and to maintain the
free flow of vehicular traffic by requiring workers
whose duties place them on or in close proximity
to a Federal-aid highway to wear high-visibility
garments
FHWA Worker Visibility Rule


Final rule published: November 24,
2006
Effective date: November 24, 2008
All workers within the right-of-way of a
Federal-aid highway who are exposed
either to traffic or to construction
equipment within the work area shall wear
high-visibility safety apparel.
23 CFR Part 634.3
High-Visibility Safety Apparel





Personal protective safety clothing provides conspicuity
during both daytime and nighttime.
Meets Performance Class 2 or 3 requirements of the
ANSI/ISEA 107-2004 publication entitled, “American
National Standard for High-Visibility Safety Apparel and
Headwear.”
Includes incident responders & volunteer workers.
Includes some exceptions for law enforcement officers &
fire fighters.
The worker visibility rule will be incorporated into the
next edition of the MUTCD to require on all public roads,
probably end of 2009.
ANSI/ISEA 107-2004





Establishes requirements for color and
minimum areas for retroreflective and
background materials.
Minimum washing cycles.
Test methods for materials.
Retroreflective materials should be placed to
ensure overall visibility of the wearer.
Garment selection shall be based on an
assessment of the work environment
ANSI/ISEA 107-2004
Performance Class 3







Roadway construction personnel and flaggers, utility
workers, survey crews, and emergency response personnel,
vehicle assistance.
Anyone who has a high task load and is in close proximity to
moving equipment or traffic at high speeds.
Work occurs at night.
Worker’s attention is diverted from on-coming traffic and
surrounding environment.
“Cluttered” work zone with high levels of activity.
Worker must be Visible from all angles and identifiable as a
person.
Worker has no separation between them and traffic.
ANSI/ISEA 107-2004
Performance Class 3


Class 3 ensemble:
Class 2 vest, Class E
bottom
Class 3 one piece:
Jacket or Coat
Torso covering garment
with full or partial sleeve
ANSI/ISEA 107-2004
Performance Class 2




Greater Visibility Needed due to
Inclement Weather Conditions
Complex and Cluttered Backgrounds
Most Work is Performed during
Daytime Hours
Worker’s Attention is Diverted from
On-Coming Traffic and Surrounding
Environment

Internal – Joe Such, Division of
Business Management (608-266-0268)
External – Tom Notbolm, Burea of
Highway Operations (608-266-0982)

ACEC, WCA, TIC, Local Government
agencies, etc.
SAFETEA-LU, Section 1110
Temporary Traffic Control Devices





Added Temporary Traffic Control as part of the
Standards in 23 USC 109.
Mandated FHWA establish rules for conditions
for appropriate use and expenditure of funds
for temporary traffic control.
Temporary Traffic Control Devices Rule
(Subpart K) Published December 5, 2007.
Effective December 4, 2008.
WisDOT is in full compliance effective
December 2, 2008.
FHWA Work Zone Safety Rule Subpart K
Established Conditions for Appropriate Use





Positive protective measures between
workers and traffic.
Uniformed law enforcement officers.
Installation & maintenance of temporary
traffic control devices.
Mandates separate pay items in contracts to
ensure projects include costs for these safety
measures when the measures are necessary.
Supplements Subpart J with additional safety
considerations.
FHWA Work Zone Safety Rule
Subpart K






Added emphasis on safety in States WZ policy
Exposure control measures: detours, lane
closures, etc.
Use of traffic control measures from
viewpoint of worker safety.
Safe entry/exit for work vehicles and
equipment
Payment for traffic control features &
operations
Quality guidelines
State Work Zone Safety Policies
The policy and related processes, procedures, and/or
guidance established under Subpart J shall include
consideration of road user and worker safety by
addressing:
 Use of positive protection devices to prevent
intrusions;
 Exposure control measures to minimize exposure;
 Other traffic control measures to minimize crashes;
 Safe entry/exit of work vehicles and equipment
onto/from the travel lanes
Key WisDOT Implementation Actions
Positive Protection Devices


Updated FDM 11-50-35 guidelines for
temporary concrete barrier to specifically
consider use of barrier at locations that place
workers at increased risk.
Updated CMM Section 1.45.9.4 to address
use of temporary barrier to shield drop-offs or
other hazards resulting from changes to
original staging and traffic control plan.
Key WisDOT Implementation Actions
Maintenance of Temporary Traffic Control
Devices




WisDOT adopted ATTSA “Quality Guidelines
for Temporary Traffic Control Devices.
Quality guidelines added to Standard
Specifications Section 643.2.1 and CMM
1.45.9.1
Replace devices the guide defines as
unacceptable.
Maintain devices the guide defines as
marginal or better.
New WisDOT Permanent
Concrete Barrier Standards

WisDOT created ad hoc work group
(DTSD Central and Region Office,
FHWA, & industry) in 2007 to examine
issues with 32” & 42” F-shape slip
formed concrete barrier.
Current Barrier Design With
Minimal Reinforcing Steel
Significant Maintenance &
Safety Issues
New WisDOT Permanent
Concrete Barrier Standards



After lengthy study determined solution
would involve new design.
Continue slip forming for
constructability and cost, NCHRP-350
crash testing compliance, timing, and
minimize maintenance were key issues.
Decision to use previously NCHRP-350
crash tested and FHWA approved
designs.
Single Slope Concrete Barrier







Developed and crash tested by Caltrans in
late 1990’s.
TL-3 NCHRP-350 approved on 2-4-1998
Excellent in-field performance
