Green beer and laughter may be a fun way to celebrate St. Patrick’s Day Sunday, but the California Highway Patrol advises not to rely on the luck of the Irish but the safety of a designated driver.

In a special press release, the CHP says they encourage celebrants to plan a safe way home and designate a non-drinking driver before the festivities begin.

According to the Sacramento office of CHP, last year on St. Patrick’s Day, the Highway Patrol made more than 300 arrests statewide for DUI. Other statistics for that day show that at least three people were killed in alcohol-involved collisions.

So, here are some more suggestions from CHP – If you are impaired, use a taxi, call a sober friend or family member, or use public transportation. If you suspect an impaired driver is on the road, report that driver by calling 9-1-1. Be prepared to give a vehicle description, license plate number, location and the vehicle’s direction of travel.

Officers also advise that “if a friend is drunk and wants to drive, encourage them not to, even if it means taking their keys away.”
