Authorities in Maryland arrested 51 people, including one of their own troopers, who were driving under the influence on area roadways over the Super Bowl weekend.

“There is zero tolerance for drinking and driving,” said Cpl. DaVaughn Parker, a spokesman for the Maryland State Police.

In one incident on Saturday around 11 p.m., state troopers responded to a crash and found a pickup truck that had driven off the road into a field in Marion, Md. in Somerset County. The driver of the pickup was an off-duty Maryland state trooper — Trooper 1st Class John Dize Jr.

In a statement, officials said Dize was later charged with driving under the influence. He was “immediately suspended with pay,” according to the statement.

Troopers were out in force over the weekend as part of a promotional effort to try to stop drunk driving and promote safer driving habits.

More than 4,700 vehicles across the state were stopped for traffic violations that ranged from speeding, aggressive driving and distracted driving. Other traffic stops involved drivers not properly wearing a seat belt, officials said.

State troopers said their initial report showed more than 2,900 traffic citations. Plus, they gave drivers more than 2,900 warnings.
