Santa Rosa police will conduct a DUI and driver’s license checkpoint at an undisclosed location Friday from 7 p.m. to 3 a.m.

Officers plan to stop every vehicle passing through the checkpoint looking for valid driver’s licenses and signs of impaired driving.

Santa Rosa police screened 801 vehicles leading to four DUI arrests and 23 drivers being cited or arrested for driving without a license during the last checkpoint Feb. 2, authorities said.

The operations are part of a California Office of Traffic Safety funded effort to crack down on drunken and drugged driving.

A single driving-under-the-influence arrest can exceed $15,000 in court costs, fees and DUI classes, police said.
