A Lexington, Ky., man sustained injuries after the truck he was riding in was involved in a rear-end collision on Monday.

Sandiago Lopez was ejected from the back of the Swartz Mowing Service pick-up truck when the vehicle was rear-ended by a vehicle driven by Adelyn S. Clements of Pleasureville around 11:30 a.m., Milton Fire Chief Jason Long said in a news release.

Lopez was airlifted by Air Methods to the University of Louisville hospital for life-threatening injuries, Trimble County Sheriff Tim Coons said. A condition on Lopez was not available this morning.

Clements was eastbound on U.S. 42 when she failed to see the slow-moving mowing service truck that was doing roadside work and rear-ended it, the police report said.

Abel Alegria of Lexington also was riding in the back of the truck that was driven by Calvin R. Armitage of Olympia, the release said.

No other injuries were reported, Long said.

The road was closed while an accident reconstruction took place.

Bedford and Milton fire departments, Kentucky State Police, the Trimble County Sheriff's Office, Trimble County EMS and Air Methods responded to the scene.
