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

A Patrol news release did not mention a specific location along Route 7, which stretches more than eight miles from Beaver Township to Youngstown in Mahoning County.

In 1990, the U.S. Supreme Court ruled that conducting sobriety tests without first notifying drivers would violate the Constitution’s provision prohibiting illegal searches and seizures.

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

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