A two-car crash about 1:40 p.m. Monday on U.S. Highway 75 injured three of the four people involved, including an infant who was thrown from one vehicle as it rolled down the highway’s embankment to the service road. The injuries were sustained by the three occupants of a Mazda, a Princeton mother and her infant and toddler children. All three were released as of Tuesday afternoon, said Van Alstyne Police Chief Tim Barnes. The fourth person, the driver of a white Ford declined medical attention, officials said.

Barnes said that the Mazda driver had pulled over onto the shoulder of the road and was pulling back onto the highway when the white Ford, shown with front-end damage on the highway, struck it from behind, and that caused it to roll downhill. With Van Alstyne EMS received information that the child had been thrown out of the vehicle, Chief Ryan Dockery immediately had dispatch summon Care Flite air ambulance to the scene.

Law enforcement from Grayson County Sheriff’s Office and Howe Police Department assisted the Van Alstyne agencies with traffic control as first responders set up the landing zone in the highway’s southbound lane for the helicopter’s landing zone. They diverted traffic off the highway onto the service road and kept it moving until the helicopter ambulance landed.

Barnes said the mother and one child were taken by regular ambulance to Medical Center in McKinney with non-life-threatening injuries. The second child was flown to Children’s Hospital in Dallas.
