GATESVILLE (September 14, 2010)--A two-vehicle head on collision Tuesday night north of Gatesville on Texas Highway 36 injured two people and forced closure of the highway for almost an hour.

A helicopter was sent to the scene to evacuate one victim who was flown to Scott and White Hospital in Temple suffering from unknown injuries.

A second victim was taken to Scott and White Hospital by Ft. Hood EMS in undisclosed condition.

Investigators believe a north bound pick up truck was attempting to pass another north bound vehicle and was unable to get back into its lane before it struck a south bound pick up.

Both vehicles were occupied only by their drivers.

The accident happened about 8:30 p.m. Tuesday some 4 miles north of Gatesville.

DPS had the highway back to normal traffic shortly after 9 p.m.

The names of those injured were not disclosed.
