Forces from all over the Valley are planning sobriety checkpoints for this upcoming weekend and through Labor Day.

The Mahoning County OVI Task Force will be conducting two checkpoints Friday through Sunday.

Details of the times and locations of the checkpoints have not yet been released.

The Task Force says there will also be saturation patrol through Mahoning County throughout the week and weekend.

The Ohio State Highway Patrol will also be conducting a sobriety checkpoint this week.

The day, time and location have not been announced.

OSP says the county where the checkpoint will take place will be released one day before the checkpoint, and the location will be announced that morning.

The Boardman Police Department says they will be cracking down on impaired drivers through Labor Day. They say they will be targeting violators for aggressive and distracted driving offenses, OVI related violations and seat belt usage.

Boardman police did not state when they would be conducting sobriety checkpoints.

During the holiday weekend of Sept. 2 through Sept. 5, the Pennsylvania State Police will be conducting checkpoints in Armstrong, Beaver, Butler, Lawrence and Mercer counties and State Route 28 in Allegheny County.

Specifics of the checkpoints have not yet been released.

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.

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