A driver was taken to the hospital after their car struck another vehicle and crashed on a low-speed section of U.S. Highway 87.  A Pontiac Grand Am was traveling downhill on the stretch of highway just off the Crow Reservation.  A Nissan Frontier was moving uphill in the opposite lane when the Grand Am drifted across the centerline, according to Montana Highway Patrol Trooper Luke Knaff. No one in the Frontier was hurt.
