<p>This report documents three full-scale vehicle crash tests that were conducted to investigate the safety performance of an open concrete bridge rail according to American Association of State Highway and Transportation Officials&rsquo; Manual for Assessing Safety Hardware 2016 (MASH 2016) Test Level 4 (TL-4) evaluation criteria. The barrier system test installation consisted of a 39-in. tall by 132-ft long open concrete bridge rail supported by 15 concrete posts. The interior posts were 36 in. long by 10 in. wide and 72-in. long by 10-in. wide posts were utilized at the upstream end section. All posts were 12 in. tall and were spaced at 108 in. on center. Test nos. OCBR-1, OCBR-2, and OCBR-3 were conducted according to test designation nos. 4-10, 4-11, and 4-12, respectively. In test no. OCBR-1, an 1100C small car impacted the barrier at speed of 64.2 mph and an angle of 25.2 degrees. In test no OCBR-2, a 2270P pickup truck impacted the barrier at a speed of 61.8 mph and an angle of 24.7 degrees. In test no. OCBR-3, a 10000S single-unit truck impacted the barrier at a speed of 56.6 mph and an angle of 15.2 degrees. In all tests, the bridge rail successfully contained and redirected the vehicles. Tests nos. OCBR-1, OCBR-2, and OCBR-3 successfully met the TL-4 safety performance criteria defined in MASH 2016.</p>
