FHWA Worker Visibility Rule 23 CFR 634
SAFETEA–LU, Section 1402:Worker Injury Prevention and Free Flow of
Vehicular Traffic
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
Worker Visibility Rule (23 CFR 634):Worker Visibility Rule (23 CFR 634):
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 107-2004Performance 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 107-2004Performance 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

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 WisDOT Standard Detail Drawings and
specifications development underway Will be used on I-94 North-South Mainline 42” will be standard for freeways and
expressways. 36” will be standard for STH and local
roads
