The Massachusetts State Police will be conducting a “sobriety checkpoint” somewhere in Suffolk County starting Friday, May 10 and running into Saturday, May 11.

The checkpoint, a roadblock which stops all traffic in one direction, is designed to remove impaired drivers, “educate the motoring public and strengthen the public’s awareness of the need for detecting and removing those drivers who operate under the influence of alcohol and/or drugs from out roadway,” State Police Superintendent Colonel Kerry Gilpin said in a release.

The exact time and place that the checkpoint will operate remains confidential to increase its effectiveness.
