ABERDEEN, Maryland - The Mahoning County OVI Task Force has announced it will be conducting two sobriety checkpoints this weekend.

The first checkpoint will be Saturday night, immediately followed by a second checkpoint early Sunday.

The specific times and locations of the checkpoints will be announced shortly before the first one begins.

There will also be local saturation patrols throughout Mahoning County this week and 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.

In their ruling, however, the justices did not spell out what they considered to be an adequate notification.

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