Rig-16 Rear Underride Guard System

For the past three years, Wabash National has spent considerable time, capital and facility resources in R&D specifically focused on enhancing rear impact guard performance. As part of these efforts, we conducted numerous crash tests, and consulted and worked with some of the premiere testing facilities in the country. The new RIG-16 system is designed to:

  • Prevent vehicle underride in multiple offset impact scenarios
  • Better absorb and deflect vehicle impact at any point along the bumper
  • Exceed U.S. (FMVSS) and Canadian (CMVSS) requirements

2017 IIHS TOUGHGUARD Award Winner

Wabash National was recognized by the Insurance Institute for Highway Safety (IIHS) for advances in preventing injuries in rear underride collisions. The RIG-16 passed a series of crash tests of a midsize car at 35 mph in three configurations: full width, 50% overlap and 30% overlap.

Key Design Features

To achieve our performance objectives, our engineering and product development teams incorporated a number of design enhancements that are engineered to work together as a system to better absorb energy and deflect impact.

  • Engineered a bolt-on, integrated rear impact guard system that better absorbs and deflects impact energy
  • Added two vertical bumper legs to the design for a total of four
  • Improved energy absorption via optimized placement of outer vertical bumper legs
  • Utilized high-strength steel construction to maximize design performance
  • Hot-dipped galvanized assembly for superior corrosion protection and longer life
