Vehicle Dynamics: A visualization of the truck’s
path was rendered. The visualization and accident are described below.
The video begins as the truck is making a left turn from Old Tampa Highway
onto KOA Power Road. According to witnesses, as the truck proceeded through
the turn the cargo bed of the trailer overlapped onto the grassy area on the
northwest corner of the intersection where a guide wire and stop sign were
located. In order to maneuver around the guide wire the driver had to stop,
back up, and move forward several times while the rear auxiliary driver
around the guide wire. The backing up and moving forward could have taken
several minutes and is not depicted in the video.
Once the truck was properly aligned the driver proceeded across the tracks
without stopping. When the truck entered the crossing, the crossing gates
were in the upright position and the signals were not flashing. At the
rear of the trailer you will see a rear or “pusher tractor”. This is attached
to the rear of the trailer and was unoccupied at the time of the accident.
Just forward of the “pusher tractor” is the platform where the auxiliary
driver was located. As the truck proceeded across the tracks the signals
began to flash and the gates descended and struck the trailer. As
the “pusher tractor” approached the tracks the auxiliary driver got off
his platform and ran clear of the crossing, avoiding injury to himself.
His actions are not depicted in the video. As the unoccupied “pusher tractor”
was being pulled across the tracks it was struck on the right side by the

The auxiliary driver was located on a platform near the rear of the tractor
combination vehicle. From the platform he could steer the rear of the trailer.
