Sobriety checkpoints and roving patrols are planned for York County for the Independence Day holiday, according for the Center for Traffic Safety.
Enforcement efforts began June 24 and will continue through July 7, and are funded with federal grant money, the center said.
A DUI checkpoint and a roving DUI patrol will be held somewhere in York County between Friday, July 5, and Sunday, July 7.
The state Department of Transportation said the crackdown is part of its "Drive Sober or Get Pulled Over" enforcement effort, which runs through Monday, July 8.
In Pennsylvania, there were 355 alcohol-related crashes with 20 fatalities during the 10-day period around the Fourth of July holiday last summer, according to PennDOT.
In addition to police patrolling roads, officers with the state Fish and Boat Commission will be watching for people operating boats while intoxicated, according to the center.
In 2012, 60 boaters were charged with "BUI," or boating under the influence, according to the Center for Traffic Safety.
