WAFF.com: North Alabama News, Radar, Weather, Sports and Jobs-New reports on bus crash shed light on safety

The only major change the school system has made since the crash on November 20, 2006 is which the bus company they use.

State safety guidelines remain the same, but new reports from the NTSB show not all procedures were being followed.

Students interviewed after the accident claimed they had never had any type of school bus evacuation training, and had no idea how the exit windows worked.

Now three years later and with a new bus company in charge, we asked the Huntsville School Superintendent what has changed.

Superintendent Ann Roy Moore said, "They do exercises with getting on and off of a bus and things like that, but you have to understand that there is a big difference in a bus going over a overpass and getting out of that."

The crash has shed light on increased safety in buses like the possibility of the state mandating seat belts in buses.

"If you have a side impact, a train, a concrete truck or toppling over an overpass, that is something so traumatic you may not be able to determine whether or not seat belts helped or not unless you have another event that is catastrophic which none of us want to see."

A spokesman for Huntsville City Schools said the best thing they can do now is make sure Durham Bus Services is following all safety guidelines, and hope a tragedy like the Lee High bus crash never happens again.
