St. Mary’s County, MD — The St. Mary’s County Sheriff’s Office is working to help keep drivers safe over the busy Labor Day Holiday weekend.

The Sheriff’s Office is working with with the assistance of the Maryland State Police and the Maryland State Highway Administration to conduct two sobriety checkpoints.

The first checkpoint will be conducted on Route 235 on Friday evening in the Lexington Park area

A second checkpoint will follow on Saturday evening in the same area.

At the checkpoints, law enforcement officers will evaluate drivers for signs of alcohol or drug impairment. Drivers will also be checked for other traffic infractions.

Often times readers will ask why the police notify drivers ahead of time, instead of just catching them in the act. There are two reasons. One, police hope that knowing about checkpoints will encourage drivers to make good decisions about driving under the influence.

Secondly, it’s required by law to notify drivers of upcoming checkpoints.
