The CHP plans two DUI/license checkpoints tonight — one in the Sonoma Valley and the other in unincorporated Santa Rosa.

A third checkpoint will be held Saturday night. That checkpoint and the CHP one near Santa Rosa are part of the Sonoma County Avoid the 13 DUI Task Force’s extra enforcement this weekend, which will include DUI saturation patrols countywide.

The Sonoma Valley checkpoint will be 6 p.m. to midnight while the Santa Rosa-area one will be 5 to 11:30 p.m. As is typical, the specific locations of all three checkpoints haven’t been announced.
