Pennsylvania State Police Troop M, Belfast, in conducting a DUI sobriety checkpoint on Northampton County roads this weekend.

Police said the initiative will be held through Sunday.

A sobriety checkpoint is a traffic safety checkpoint wherein troopers systematically stop vehicles at selected locations to briefly observe drivers for articulable facts and/or behaviors normally associated with alcohol or drug impairment.

The goal of a sobriety checkpoint is to reduce the number of alcohol and drug related fatal and serious crashes, and to reduce the number of DUI drivers on Pennsylvania’s highways.
