Highway Accident Brief: Tire deflation and tread separation, cross-median crash

Executive Summary

​On Saturday, February 15, 2014, about 11:30 a.m. local time, a 2004 Kia Sorento sport utility vehicle (SUV), occupied by a 37-year-old driver and four passengers, was traveling westbound on US Route 90 (US-90) near Centerville, Louisiana. The SUV was traveling in the right lane at a witness-estimated speed of 70 mph (roadway speed limit) when the driver lost control of the vehicle due to a tread separation and rapid air loss in the left rear tire. The SUV veered into the left westbound lane, rotating in a counterclockwise direction, and departed the roadway into a 64-foot-wide depressed earthen median. It continued through the median, now rotating in a clockwise direction; entered the eastbound traffic lanes of US-90; and collided with a 2005 IC Bus (66-passenger school bus), which was traveling in the right lane.1 The left front of the SUV contacted the right front of the school bus, resulting in the rapid clockwise rotation of the SUV and secondary impacts along the right side of the school bus. The driver of the SUV and three rear passengers were ejected. The fourth passenger remained in the vehicle.

Probable Cause

​The National Transportation Safety Board determines that the probable cause of the Centerville, Louisiana, crash was the Kia SUV driver’s loss of control due to the tread separation and rapid air loss of the left rear tire, which altered vehicle handling characteristics. Contributing to the crash was the deteriorated condition of the tire due to inadequate maintenance.
