Partygoers are being asked to plan ahead to avoid tragedy this St. Patrick’s Day.

MADD Canada, the Canadian arm of Mothers Against Drunk Driving, is urging St. Patrick’s Day revellers to never drive impaired and instead to arrange a designated driver, call a cab, take an Uber, or ride public transit.

As well, everyone should avoid riding with a driver who is impaired and report suspected impaired drivers by calling 911.

“When you’re out celebrating St. Patrick’s Day [today] or throughout the weekend, please don’t rely on luck to get home safely,” said MADD Canada National President Jaymie-Lyne Hancock in a news release. “Take a few minutes ahead of time to plan your sober transportation. It can prevent a tragedy, and a lifetime of grief and heartache for you and those on the road around you.”

MADD Canada said impaired driving continues to be a deadly problem on Canadian roads in spite of laws, police efforts and awareness initiatives. Every year, hundreds of Canadians are killed and thousands are injured in crashes involving alcohol, cannabis, or other drugs.
