HELENA, Mont. (AP) — A Wyoming man was killed and a North Dakota man was seriously injured in a head-on crash on a secondary highway in northeastern Montana.

The Montana Highway Patrol says Secondary 201 was icy at 6:20 a.m. Sunday when a pickup driven by a 38-year-old man from Sheridan, Wyo., slid across the center line and into the path of a westbound vehicle driven by a 59-year-old man from Williston, N.D.

The Wyoming man died at the scene of the crash west of Sidney, while the North Dakota man was taken to a Billings hospital for treatment. His condition wasn't immediately available.

Neither man was wearing a seatbelt. Their names have not been released.
