CANFIELD, Ohio - People driving in Mahoning County may see more police, deputies, and state troopers on the roads this weekend.

A news release from the Mahoning County OVI Task Force says local law enforcement agencies will take part in saturation patrols Friday, Saturday, and Sunday.

In addition, the Task Force says it will hold multiple sobriety checkpoints over the weekend.

The times and locations of the checkpoints will be made public shortly before they 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.

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