Sobriety checkpoints, called OVI checkpoints in Ohio, are announced ahead of time by the agencies that run them. This page lists the ones announced in Montgomery, Greene, Miami, Warren, Clark, Darke, Preble and Butler counties: the date, time window and general location as each agency’s own release gives them, with a link to the release. Agencies often give the exact location only on the day of the checkpoint. When an agency publishes a checkpoint’s results, the counts appear with it.
