People driving in York County this weekend could find themselves stopped at a sobriety checkpoint.

It will be held sometime between 6 p.m. Friday and 6 p.m. Saturday, according to the Center for Traffic Safety.

Checkpoints are announced in advance, but roving DUI patrols may or may not be announced in advance, according to the center. Enforcement activities are focused on roads that have a high incidence of DUI arrests and crashes.

Checkpoints, roving patrols and related police activities are funded with federal grant money distributed by the state Department of Transportation.
