Looking to get ghoulishly drunk this Halloween weekend? You may want to reconsider driving home.

Sobriety checkpoints will be set up in York, Adams and Lancaster counties as part of the Center for Traffic Safety's Sobriety Checkpoint and Expanded DUI/Underage Drinking Enforcement Program.

Enforcement activities will be between 6 p.m. Friday and 6 p.m. Sunday, according to the center.

Sobriety checkpoints, roving DUI patrols, and other enforcement activities organized as part of this program are funded with federal grant money provided by the state's Department of Transportation, and established on roads that have proven to be high incidence for impaired drivers both in terms of crashes and arrests.

Sobriety checkpoints are announced in advance, but roving DUI patrols and other related enforcement activities may or may not be announced in advance.
