SAN ANTONIO – The Bexar County Medical Examiner's Office identified a 23-year-old woman killed after colliding with a rig while driving the wrong way on Highway 151 early Friday morning.

Police said Wendy Vega was traveling in the wrong direction on Highway 151 around 3 a.m. Friday morning when she crashed into what authorities described as a "flasher equipment paint striping rig."

A 24-year-old passenger in Vega's truck and the driver of the rig were taken to University Hospital with life-threatening injuries.

The Texas Department of Public Safety closed down Highway 151 near Military Drive for several hours Friday morning.

At one point, authorities shut down traffic in both directions as first responders worked to get everyone out of the vehicles involved in the crash.

Hazmat crews were called to drain the wrecked paint truck before flipping over wreckage.
