Rear-End and Underride Crashes
Driver fatigue, distraction, or following too close, combined with 80,000 pounds of mass, equals catastrophic rear impact. Underride crashes: where a passenger car slides under the trailer: are often fatal or cause severe head and neck trauma. Federal underride guard standards exist (49 CFR 393.86) but enforcement is weak. We pursue rear-impact guard violations and trailer conspicuity tape failures.
