Irving, TX (CNN) — Texas authorities are trying to figure out how a charter bus driver lost control and crashed Thursday in Irving.
Two people are dead and dozens more were injured in the wreck.
The bus was carrying senior citizens on a casino excursion to Oklahoma.
Daniel Risik was a passenger and describes the chaos that unfolded inside the bus after the crash.
"Well, basically we were just moving up the highway and traffic was quite light, so we were probably going at least the speed limit or close there to and, all of a sudden, the vehicle started to swerve and people started yelling and screaming," said Risik. "Then, there was a loud crash and then, almost instantly after that, the bus was laying on its side and people were crying out, hollering, calling for help. some of those look like they were very severely injured. blood flowing from their heads. it was quite a sight."
The bus driver is hospitalized in critical condition.
Federal records show the the bus company operator, Cardinal Coach Line, has a "satisfactory" safety record.
It also has no major violations in the last two years.
