The Mahoning County OVI Task Force announced that they plan to conduct a sobriety checkpoint Friday night.

The Task Force is expected to release the location and exact time of the checkpoint shortly before it begins.

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.
