The Steel And Foam Energy Reduction Barrier (SAFER Barrier), sometimes generically referred to as a soft wall, is a technology found on oval automobile race tracks and high speed sections of road and street tracks, intended to absorb and reduce kinetic energy during the impact of a high speed crash, and thus, lessen injuries sustained to drivers and spectators. It was designed by a team of engineers at the Midwest Roadside Safety Facility at the University of Nebraska-Lincoln. It was developed from 1998–2002, and first installed at the Indianapolis Motor Speedway in May 2002.

The SAFER barrier consists of structural steel tubes welded together in a flush mounting, strapped in place to the existing concrete retaining wall. Behind these tubes are bundles of closed-cell polystyrene foam, placed between the barrier and wall. The theory behind the design is that the barrier absorbs a portion of the kinetic energy released when a race car makes contact with the wall. This energy is dissipated along a longer portion of the wall. The impact energy to the car and driver are reduced, and the car is likewise not propelled back into traffic on the racing surface.

The SAFER barrier also lessens damage to the car itself, thereby reducing repair costs. After its introduction in 2002, nearly every oval track on the IndyCar and NASCAR circuits had the device installed by 2005. Road and street tracks apply SAFER barriers on high speed cornering sections where space is limited.

The SAFER Barrier and its developers have won several awards within the racing and engineering community, including the Louis Schwitzer Award, Pocono Raceway Bill France, Sr. Award of Excellence, NASCAR Bill France Jr. Award of Excellence, R&D 100 Award, SEMA Motorsports Engineering Award, GM Racing Pioneer Award, Autosport Pioneering and Innovation Award. Dean Sicking received the National Science and Technology Medal from President George W. Bush, in part due to his work on the SAFER Barrier and on other roadside safety devices.[1][2]
