The Hoover school board Friday fired a bus driver arrested for DUI. The vote to terminate Mark Pierce came in a special called meeting. Pierce crashed his bus on I-459 northbound near Acton Road this week. There were no students aboard at the time. But Pierce had just driven home about 35 Spain Park High School students shortly before the wreck. Superintendent Kathy Murphy said the board's vote speaks to the issue at hand, but declined further comment on the advice of lawyers.
