About 1:57 p.m. central daylight time on Sunday, March 20, 2016, a 2013 Hyundai Elantra passenger car (Hyundai) occupied by an 18-year-old driver and three passengers, ranging in age from 17 to 19, was traveling northbound in the left lane of US Highway 77 (US-77) in the city of Robstown, Nueces County, Texas.
This section of US-77 consisted of four lanes, divided by a 42-foot-wide median. The Hyundai began drifting left toward the center median and entered the median edge at a location that included a left-turn lane. Upon entering the median, the driver attempted to steer the vehicle back into the northbound lanes but ultimately lost control of the vehicle. The Hyundai crossed the center median and entered into the southbound traffic lanes, where it collided with a 2009 Freightliner truck-tractor in combination with a 2014 flatbed semitrailer (Freightliner). As a result of the crash, the driver of the Hyundai was seriously injured and the three passengers died. The driver of the Freightliner was not injured.
