A safety guardrail is a component which prevents passage into a dangerous area. It is commonly used to mitigate risk in the Hazard-Guardrail-Target model, as studied in safety science.
Physically separate the work area and the traveled way are designed to resist penetration of an out-of-control vehicle and have properties which redirect an out-of-control vehicle back on to the road away from the work area.
Hard guardrails are fixed into the ground as a bollard or gate, removable on stands, or clipped to a structure. Regardless of the guardrail type, the components and overall assembly will be similar.
