The "Fitch Highway Barrier System," created by race car driver John Fitch, features a series of impact attenuators arranged in a triangular pattern at the tip of a guardrail, specifically in the gore area between a highway and an exit lane. Designed to mitigate the effects of vehicle collisions, the system incorporates barrels filled with sand that progressively increase in capacity. When a vehicle strikes the barriers, they break apart, and the sand disperses, smoothly decelerating the vehicle. This design significantly reduces the risk of injury to occupants, providing a safer road experience.

The "Fitch Highway Barrier System", invented by race car driverJohn Fitch, comprises a series of such impact attenuators often found in a triangular arrangement at the tip of a guardrail between a highway and an exit lane (the area known as the gore), along the most probable line of impact. The barriers in front contain the least sand, with each successive barrel containing more; so that when a vehicle collides with the barrels they shatter, the kinetic energy is dissipated by scattering the sand, and the vehicle decelerates smoothly instead of violently striking a solid obstruction, reducing the risk of injury to the occupants
