State police at the Hazleton barracks have released the results of a sobriety checkpoint initiative officers held over a recent weekend on roads in lower Luzerne and upper Schuylkill counties.

Police said one driver was arrested for driving under the influence of alcohol or a controlled substance and 14 traffic citations were issued for violations of the Pennsylvania Motor Vehicle Code.

Twenty-one drivers were issued warnings for violations, police said.

They said that two motorists were interviewed but were released after passing standardized field sobriety tests.
