A guardrail on the side of a paved road.

This two-day class focuses on guardrail identification and inspection. During the workshop, you will learn about standard guardrail systems, guardrail location and special situations, length of need, guardrail transitions, and guardrail end treatments; participate in identification activities; take a post-assessment; and use a supplemental workshop resource handout. The course curriculum will feature Minnesota-specific examples and interactive demonstrations, and special focus areas will include Minnesota standard plates and plans, bullnose guardrails, and addressing grading standards on guardrail systems.
