Video of the bus driver, whose name was not reported, was captured Sept. 13 by the daughter of Venus Cotto-Silva, ABC News reported.
In the video, the driver is seen with one hand on the wheel while looking at her phone, which is in her other hand. At one point, the driver looks up from her phone, then suddenly grabs the wheel with both hands to avoid traffic.
"When she showed me the video, I just couldn't believe it," Cotto-Silva said. "The scary part is, see how quickly she grabbed the wheel?"
Cotto-Silva said her daughter, an eighth grader at a Hillsborough County school, was trying to capture evidence that the bus driver swears, but instead caught her texting and driving.
In a statement, the school district said texting while driving is against policy for its bus drivers and that the driver in question had been suspended.
"Clearly the driver is looking at her cellphone. That's a dangerous distraction for any driver, but the potential danger is greater when you have a bus full of children," the statement said.
