YOUNGSTOWN - The Mahoning County OVI Task Force and the Ohio State Highway Patrol have announced the time and location of a checkpoint Friday night.

According to a news release, the checkpoint will be set up along Glenwood Avenue and Playhouse Lane on Youngstown's South Side between 10 p.m. Friday and 2 a.m. Saturday.

Area law enforcement agencies are also taking part in saturation patrols this weekend.

In 1990 the U.S. Supreme court ruled that holding sobriety checkpoints without first notifying drivers would violate the Constitution's provision barring illegal search and seizure.

However, in their ruling, the justices did not spell out what they considered to be adequate notification.

That same year, the National Highway Traffic Safety Administration published recommended procedures for OVI checkpoints, including notifying the media of the planned roadblocks.
