The Saint Patrick's Day weekend was a busy time for Frederick Police officers, who made arrests for driving under the influence and drug offenses. It was all part of an effort to keep the roads safe during a weekend when there's often a lot of drinking.

Frederick and Brunswick Police officers set up a checkpoint in the downtown area on Friday night, and at Rosemont Avenue and 7th street.

Authorities say saturation patrols were also conducted on Saturday evening, which resulted in 69 traffic stops and 30 equipment repair orders. There was also one arrest for driving under the influence, and three criminal citations were issued for possession of marijuana.

These efforts during the past weekend are part of a  spring DUI initiative. The Frederick Police Department is taking part in this effort with Maryland Highway Safety Office, which aims to bring down the number of alcohol-related deaths to zero. There have been 800 DUI-related vehicle crashes in Maryland since 2007, according to the National Highway Traffic Safety Administration.
