CANFIELD, Ohio - Saint Patrick's Day is over, but efforts to keep impaired drivers off Mahoning County roads are not.

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

The checkpoint is scheduled to run Friday night from 10:00 p.m. until 2:00 a.m. at 4477, Mahoning Ave. in Austintown.

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.
