During a July 29 sobriety checkpoint in Chesapeake Beach, three people were arrested for violating Maryland’s driving under the influence of drugs or alcohol laws.

The Calvert County Sheriff’s Office and the Maryland State Police Prince Frederick Barrack conducted a sobriety checkpoint July 29 on Breezy Point Road near the Breeze Inn Country Store, according to a sheriff’s office press release.

“The hard work of our deputies and troopers during this checkpoint may have saved some lives this weekend,” Sheriff Mike Evans (R) said in a written statement. “I can only hope that the message gets out to all motorists that laws against driving under the influence of alcohol and drugs will be strictly enforced in Calvert County.”

The checkpoint, which was funded through grant funds from the Maryland Highway Safety Office, was conducted as a continuing effort to educate citizens traveling county roads about the dangers involved with drinking alcohol and then driving a vehicle, the press release states. Signs alerting drivers of the upcoming checkpoints were placed about 100 yards from the beginning of the checkpoint, which ran from 5:39 to 8:18 p.m.

A total of 529 vehicles entered the checkpoint, the press release states. Nine of those vehicles were taken to testing areas for suspected violations, and three drivers were arrested. Two people were arrested by troopers on routine patrols, according to the press release.
