State and local law enforcement agencies will be conducting sobriety checkpoints and roving patrols across the state this holiday season.

As part of Operation Safe Holiday, state police will conduct seatbelt, aggressive-driving and impaired-driving enforcement, according to state police.

Police in York, Adams and Lancaster counties will also step up their enforcement of drunken driving as part of the program, which ends Jan. 2, the Center for Traffic Safety had previously said.

DUI checkpoints, roving DUI patrols and other programs designed to combat intoxicated driving are funded with federal grant money disbursed by the state Department of Transportation.
