It's an effort to remove impaired drivers from the roads.
Saturation patrols were conducted on Saturday evening in Frederick. Authorities say seven officers were deployed, along with one dedicated dispatcher between 8:30 PM and 2:30 AM.
During that time, three motorists who were operating under the influence were arrested, and one driver was cited for not having a license, and must appear in court.
The Frederick Police Department conducted the saturation patrols through funding from Project SOLO, or Save Our Loved Ones. The grant comes from the Motor Vehicle Administration's Maryland Highway Safety Office. Project SOLO deploys mass patrols on area roads which are known to have higher instances of alcohol-related crashes.
Officers will be conducting checkpoint and enforcement operations during the month of December to help reduce drug and alcohol-related crashes.
"Project SOLO is about taking impaired drivers off the road, saving lives and raising awareness about the importance of safe driving," says Lt. Dennis Dudley, Commander of Professional Services, Frederick Police Department, in a statement. "Every law enforcement official involved in this initiative is thoroughly trained and briefed to effectively target impaired driving.
