CHILLICOTHE, Ohio — The Ohio State Highway Patrol has announced it will operate an OVI sobriety checkpoint somewhere in southern Ohio this week, with the specific county to be announced the day before and the exact location revealed the morning of the checkpoint.
Local law enforcement agencies will provide operational support during the checkpoint.
Troopers are urging anyone who plans to consume alcohol to designate a driver or make other travel arrangements before drinking.
Why the patrol announces checkpoints in advance
Ohio law requires law enforcement to publicly announce sobriety checkpoints before they are conducted. The requirement stems from a 1990 U.S. Supreme Court ruling in Michigan Department of State Police v. Sitz, which upheld the constitutionality of sobriety checkpoints but established that agencies must follow specific procedures to ensure they do not violate Fourth Amendment protections against unreasonable search and seizure.
In Ohio, that means law enforcement must give the public advance notice that a checkpoint will occur — though agencies are not required to reveal the exact location in advance. The advance notice requirement is designed to balance the government’s interest in keeping impaired drivers off the road with the public’s constitutional rights. The theory is that the deterrent effect of a checkpoint — drivers knowing one is coming and choosing not to drink and drive — serves a legitimate public safety purpose even if some impaired drivers avoid the specific location.
In short, the announcement is not a courtesy. It is the law.
