A 26-year-old Montgomery County man died in a crash in Baltimore County when his vehicle hit the side of a tractor-trailer as the truck attempted a U-turn, state police said. The accident closed part of Interstate 70 early Saturday morning.

Around 2:30 a.m. Saturday, Maryland State Police responded to a crash between a Chevy Suburban and a tractor-trailer near the interchange of Interstates 70 and 695 in Woodlawn, according to authorities. Police found Cabin John resident Michael Kenneth Nemes, who drove the sports-utility vehicle, dead at the scene.

According to witnesses, the Chevy hit the side of the tractor-trailer as its driver attempted to make a U-turn, authorities said. The Chevy became pinned under the tractor-trailer, and Nemes was trapped, they said.

Sgt. Douglas Forrester, a state police supervisor, said the tractor-trailer made an illegal U-turn, but whether the driver will be charged was pending Saturday. Authorities say Nemes was not wearing a seatbelt at the time of collision. It remained unclear whether alcohol was involved, Forrester said.

The eastern side of Interstate 70 was shut down when police arrived at the scene, Forrester said, but reopened to traffic around 6:30. a.m.
