The Ohio State Highway Patrol announced that it will conduct an OVI checkpoint along Route 7 in Mahoning County from 10 p.m. until midnight Friday.

A media release from the Patrol does not give a specific location along Route 7, which stretches more than a dozen miles from Beaver Township to Youngstown in Mahoning 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.

However, in their ruling, the justices did not specify what they considered 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.
