Witnesses say flames shot 10 feet into the air.
A plume of black smoke rising from the burning truck could be seen for miles.
Police initially closed St. Augustine Road from from University Blvd to Rolac Road and Powers Avenue from St. Augustine Road until the fire was out.
When the smoke turned white, it showed the fire was under control.
Firefighters used foam to put out the fuel-fed fire.
There was no immediate word of what caused the fire.
All roads in the area were reopened within the hour.
