Drunken Arizona drivers with the late-night munchies may soon be getting more than chicken strips at drive-through windows.

The Pima County Sheriff's Department has a new campaign targeting drunken driving. Operation Would U Like Fries, or Operation WULF, will put undercover deputies inside 24-hour fast-food restaurants to spot impaired drivers placing their orders.

Sgt. Doug Hanna, a DUI unit supervisor, says if deputies notice someone with classic symptoms of impairment — slurred speech, red or watery eyes or beer breath — they will have a uniformed deputy stationed outside pull the driver over.

Hanna says money for the intermittent program is coming from a $128,000 grant from the Governor's Office of Highway Safety.
