Four people, including two children, were injured when a car collided with a semi-trailer Thursday morning east of Grayson College.


The semi-trailer was traveling westbound on FM 691 while a Toyota car was driving eastbound near Travis Street. Texas Department of Public Safety Trooper Mark Tackett said the semi-trailer made an unsafe left turn in front of the Toyota driven by 36-year-old Trisha Clinkscales of Denison. At about 7:35 a.m., the car collided with the semi-trailer, injuring the four Toyota occupants. Tackett said the semi-trailer was turning into an open area on the south side of FM 691.


Clinkscales and the male passenger in the front seat were transported to the Texoma Medical Center for treatment of injuries sustained in the crash, Tackett said. Two children were in the backseat of the vehicle, one child was immediately transported by helicopter to a Dallas-area hospital. The second child was transported to TMC, evaluated, then transported the same Dallas-area hospital. Tackett said both children were in critical condition and the extent of their injuries was not known.


The driver of the semi-trailer was identified as Stormy Henderson, and he was not injured, Tackett said. No other vehicles were involved in the crash, and Tackett noted that all Toyota occupants were wearing seat belts.
