Traffic was backed up for hours on U.S. 421 after an accident involving a car and semi-truck Friday afternoon in Trimble County.

The crash near Palmyra Road at 1:30 p.m. resulted in one person being airlifted and three others being taken to area hospitals with non-life threatening injuries.

A broken diesel fuel tank required closing both lanes of the road while emergency crews cleared the scene.

Police said a car, driven by 18-year-old Drew A. Martin of Highland Heights, failed to stop at the stop sign on Palmyra Road and was struck by an oncoming semi-truck.

The car spun around in the road after impact with the truck, driven by 53-year-old Roberto Gonzalez of Lehigh Acres, Fla., and became lodged under the trailer, Trimble County Sheriff's Deputy Tom Starks said.

Gonzalez had swerved into the southbound lane of U.S. 421 in an attempt to avoid the collision and went off the west side of the road.

The car broke free from the trailer after Gonzalez brought the truck back onto the roadway, and Martin's vehicle ended up in the ditch on the northbound side of the road, Starks said.

The truck jackknifed while Gonzalez attempted to gain control of the vehicle and punctured a diesel fuel tank. After coming to a stop, the truck blocked both lanes of the roadway.

The two drivers and two passengers in Martin's vehicle - 18-year-old Abigaill M. Melton of Sanders and 18-year-old Sean Blackburg of Warsaw - were transported to area hospitals with non-life threatening injuries, Starks said.

Martin was transported by Air Methods to the University of Louisville Hospital, and Gonzalez was transported by ambulance to Baptist Health LaGrange.

One passenger in Martin's car was transported by ambulance to King's Daughters' Health in Madison, while the other was transported by ambulance to Baptist Health LaGrange.

Motorists backed up in the southbound lane of U.S. 421 for miles during a nearly two-and-a-half-hour wait while crews worked to clear the scene and clean the spill from the road.

Oncoming traffic traveling in the northbound lane of U.S. 421 was detoured onto Milton-Bedford Pike around the accident.

Hazmat crews remained at the scene until 4 p.m. cleaning up the diesel spill, which had run off into a ditch.
