Tennessee Transportation Assistance Program, in partnership with the Tennessee Department of Transportation and the Federal Highway Administration, would like to provide you with the opportunity to attend a series of virtual live workshops on guardrail systems. This program is funded under the FHWA FAST ACT with the objective of improving the safety of our nation's highways.

This training will help participants:

  • verify that a traffic barrier (guardrail) is the best treatment to use at a specific site,
  • understand the principles of good guardrail system design,
  • identify installations that may not adequately shield all the significant hazards or secondary hazards, and
  • recognize common installation and maintenance errors for guardrail runs and terminals and know how to avoid them.

This workshop is divided into three sessions. All participants must participate in Session 1. Session 2A primarily addresses engineers who are responsible for the design of guardrail systems. Session 2B targets the needs of local agency personnel who are responsible for the installation, maintenance, and inspection of guardrail systems. Most participants will only need to attend two of the three sessions, but you may attend all three sessions.


This training is provided to all local agency (counties, cities, and towns) personnel in Tennessee who are responsible for the design, installation, inspection, or maintenance of guardrail systems.
