With roving saturation patrols and a DUI checkpoint over the Halloween weekend, Modesto police nabbed 22 suspected drunk drivers.
Extra patrols started Friday and led to four arrest.
Eleven of the offenders were caught Saturday night at a DUI checkpoint on I Street between Sixth and Seventh streets. Five others were arrested by patrol units.
Activity slowed on Halloween with just two DUI arrests.
The enforcement effort was funded by a state Office of Traffic Safety grant.
