Guidelines for the Use of Positive Protection in Work Zones

Positive protection devices that contain and/or redirect vehicles and meet crashworthiness evaluation criteria should prevent intrusion into the work area. These guidelines address the use of positive protection devices in work zones to supplement the Policy Directive Work Zone Safety and Mobility Policy 805.0 and comply with the FHWA Final Rule Subpart K to CFR Part 630. These guidelines are not a stand-alone document on work zone application of positive protection and should be used in conjunction with other traffic control standards and resources.
