A man is on the way to the hospital Tuesday night after his car went into a creek in the unincorporated part of Dallas County.
The Dallas County Sheriff's Office said there was only one vehicle involved in the crash near Belt Line Road and East Tripp Road.
Authorities do not know what caused the crash.
The vehicle is completely submerged in the creek.
Sunnyvale firefighters were able to pull one man from the car, but they do not know if anyone else was inside.
That person has been transported to Dallas Regional Hospital in Mesquite.
