Police said they arrived at the scene around 10:05 p.m. to find Dee -- born Taylor Dawn Carroll -- in "grave condition" a short distance outside of the vehicle.
"A 36 year [sic.] male, who was also an occupant of the vehicle, was found outside the vehicle with non-life threatening injuries," said the release.
Authorities believe Dee was driving the car and was not wearing a seatbelt and that alcohol "may be a contributing factor."
They added: "The investigation is currently ongoing but it does not appear there will be any criminal charges related to the collision."
According to online records from the Tarrant County Medical Examiner's Office, she died at 10:52 p.m. at a hospital.
Her cause and manner of death are still pending. She is slated for an autopsy.
"Investigators determined the Chevrolet Trailblazer was attempting to make an abrupt lane change to exit the TEXpress lane when it struck a crash cushion barrier," the release added. "The impact caused the Trailblazer to then flip into the air, striking a vertical steel highway sign with its roof before coming to rest upside down on the highway."
