The St. Patrick's Day holiday is a dangerous one on the roads due to drunken driving, according to Howard County Police.

As a result, they will increase patrols this weekend. 

“We are asking people to use good judgment and celebrate safely," said Police Chief Bill McMahon in a news release. "If you are planning on drinking, please designate a driver first.”

In 2011, 38 people were killed in the U.S. on St. Patrick's Day or the next morning in drunken driving incidents, according to the release, which cites information from the National Highway Traffic Safety Administration.

A saturation patrol will be set up to identify impaired drivers, the release said.
