At least four were injured at North Texas Jellystone Park on Sunday after a collision between a truck and golf cart.
Rescue workers responded to the scene about 11 a.m. to find that the driver of a Chevy Silverado, a 36-year-old man, had suffered an apparent medical issue, causing him to lose control and crash into a golf cart carrying three people, according to reports.
The driver of the truck and one person in the golf cart were transported by air to a nearby hospital in critical condition. The other two in the golf cart were transported by ambulance.
The incident remains under investigation.
