They can weigh nearly 12,000 pounds and could cause a lot of destruction with the wrong person behind the wheel.

That’s why one shouldn’t be inebriated while driving a Zamboni, a hockey rink ice resurfacer.

But that’s exactly what police say Steven Anderson was while he was driving at Fargo’s South Arena.

“I’ve been here for 22 years … and we have not had an incident like this before,” said Jim Larson, director of finance and human resources for the Fargo Park District, which operates the arena, the Duluth News Tribune reports.

Two high school girls’ teams from Davies High School and Williston High School were playing. During the 2nd intermission, “spectators and school officials noticed the erratic Zamboni driving” and called police.

Fargo Police Lt. Joel Vettel tells the Fargo Forum that even though the Anderson was not on a public street, state law dictates anybody “operating a motor vehicle while heavily under the influence of drugs or alcohol be arrested.”

“Certainly this is a very unique situation, one that to my knowledge we have not seen here in the city of Fargo,” Vettel says.

The news site reports Anderson was arrested and convicted of another DUI charge in December.

He pleaded guilty and ordered to serve 20 hours of community service and banned from drinking until January 6.

“I don’t want to in any way dismiss how serious this is,” Larson tells the News Tribune. “We’ll review the situation to determine how this happened and what we can do to make it even more fool proof.”

As for the girls’ hockey game, another Zamboni driver was called, but the teams elected to skate on rough ice instead of waiting for the new driver to arrive.
