LEE COUNTY, Fla. - Investigators from the National Transportation Safety Board are in Missouri to look at the horrific accident that killed a 15-year-old on a school bus and the driver of another vehicle.

Investigators are looking into school bus safety and construction zone safety as they try to determine the cause of the wreck.

The accident happened Thursday as a semi-cab slowed for road construction and was hit by a pick-up truck. Two buses carrying band students then slammed into that wreck.

We wanted to know how safe our buses are in Lee County. We also found out what is takes to be a bus driver.

It takes a lot to get behind the wheel of a Lee County School bus, and if you're on board - the district says you are safe.

First, a driver has to go through 50 hours of class and driver training to get a commercial drivers license, but that's not all. Before every school year...

"Each bus operator goes through a refresher training of 16 hours. It covers bullying, student management techniques, railroad crossings, what to look for in the event that a child is diabetic, or any type of little thing like that."

"The same rules the students has in the school - that's what they follow on the bus."

All buses have three cameras on board, seat belts, a GPS that lets the school district know where they are at all times, and a child reminder system.

"It forces the bus operator to walk to the back of the bus prior to exiting the bus to ensure there are no students on the bus."

Last year, Lee County had less than 200 school bus accidents. Almost all of them were minor.

The district also has a 12 year replacement policy on all their buses.

Lee County has 675 buses; 1300 routes; 5500 students to transport; start paying bus drivers at $13.02 per hour; and the buses cannot drive more than 55 miles per hour.
