The Mahoning County OVI Task Force will be conducting a sobriety checkpoint on Saturday and saturation patrols through the weekend.

The Task Force is expected to reveal the specific time and location shortly before the checkpoint is scheduled to begin.

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.
