Drivers in Mahoning and Columbiana counties may encounter an OVI sobriety checkpoint over the next couple of days.

The Ohio State Highway Patrol announced on Thursday that it will conduct a checkpoint in Columbiana County Friday night.

Troopers say they'll reveal a more specific location Friday morning.

The Mahoning County OVI Task Force also says it will conduct a checkpoint sometime between Friday and Sunday.

There will also be local saturation patrols throughout the county.

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.

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