The Butler County OVI Task Force will conduct an OVI checkpoint tonight in Hamilton.
The sobriety checkpoint will be from 10 p.m. to 2 a.m. Saturday at 2210 S. Erie Blvd.
State law requires that law enforcement announce the times and locations of checkpoints ahead of time.
The task force uses checkpoints and surrounding patrols, called saturation patrols, to deter impaired driving.
