There is a lack of public domain metal guardrail systems that are compliant with the American Association of State Highway and Transportation Officials Manual for Assessing Safety Hardware (MASH) Test Level 4 (TL-4). This test level is used for assessing barriers that are designed to contain passenger and freight vehicles. Several corridors in Texas are known to experience a larger percentage of freight and truck traffic. In these corridors, the safety of the motoring public can greatly benefit from the use of a MASH TL-4 compliant metal guardrail system. Some concrete barrier designs are MASH TL-4 compliant; however, a metal guardrail system can be more economical than a concrete barrier system. The Texas Department of Transportation (TxDOT) desired a metal guardrail system that meets the testing requirements of MASH TL-4, which involves testing with a 2,420-lb small passenger sedan, a 5,000-lb pickup truck, and a 22,000-lb single-unit truck.
