Ohio law requires that law enforcement announce checkpoint times and locations.
Task force officials ask people to dial 911 or #677 if they see an impaired driver.
An impaired driving checkpoint is scheduled for today in Hamilton.
The checkpoint is 6-10 p.m. on U.S. 27 (Pleasant Avenue) at Hayes Avenue. Members of the Butler County OVI Task Force will be looking for various things in an effort to reduce impaired driving crashes.
