One person is dead after a semi-truck pulling three trailers drove off Interstate 84 near Caldwell Tuesday morning.

CALDWELL - A Kuna man is dead after a semi-truck carrying two flatbed trailers drove off Interstate 84 in Payette County around 5:30 a.m. Tuesday.

Idaho State Police say 66-year-old Donald Pasma was westbound on I-84 when for unknown reasons he drove off the left shoulder at milepost 16, about one mile west of Sand Hollow Road - near the Payette-Canyon County line. The truck went through the median, over an overpass for a small farm road and crashed into a retaining wall.

The impact of the crash was so severe that the two trailers landed on top of each other.

"He was still in the vehicle and he was taken out by the jaws of life," said ISP Trooper Brandon Bake.

Pasma was pronounced dead at the scene.

Idaho State Police, Canyon County and Payette County Sheriff's deputies responded to the crash along with Payette, Middleton and Caldwell fire departments.

Some witnesses reported smoke and flames coming from the accident scene.

"So far it's still under investigation we don't know why. The witnesses that we had they said they didn't notice anything strange or unusual when they drove by this semi truck or vehicle," said Trooper Bake. 

The left lane on westbound I-84 was blocked for several hours while emergency crews responded and the trailer and truck were removed.

The crash is being investigation by an Idaho State Police crash reconstruction team.

Donald Pasma was the owner of D-P Trucking in Kuna.
