One of the primary functions of a Highway Guardrail System is to prevent vehicles from veering off the road, particularly in high-speed areas. These guardrails absorb impact energy during collisions, thereby minimizing the risk of serious injury or fatality.

The design of these systems often includes advanced features such as flexible posts and high-tensile steel, improving their ability to withstand impacts compared to traditional barriers.
