The driver was identified as Nakharin Boonchai, 58, a Bangkok resident.
His badly-damaged pickup was found on a road in Ban Kud Kla Phan Suek in Tambon Moo Si.
Rescuers had to use an iron cutter to remove his body which was trapped behind the wheel.
Khanchit Srinoppawan, chief of the Khaoyai National Park, who inspected the scene with police and rescuers, noticed footsteps of a large elephant at the spot, which showed the elephant walked back into the forest.
Officials believe the pickup hit a large elephant as the road was dark and the driver could not see the pachyderm.
Khanchit said wild elephants often roamed in the area, called Chao Duan. Park officials will try to locate the elephant which is likely injured.
The road is often crossed by wild elephants at that point because it divides Khaoyai National Park and a corn plantation.
Early this month, a pickup truck driver was injured when his vehicle hit a wild elephant at the same location.
Officials plan to install street lamps at the location to prevent further accidents.
