A North Dakota resident found out the hard way this past weekend that kilometres and miles aren't the same thing.

The driver was hit with a $940 ticket Sunday afternoon after being caught going 100 miles per hour in the RM of Dufferin on Highway 13, RCMP said.

RCMP's radar gun caught the driver going 168 kilometres per hour, just over 100 mph, in a 100 km/h zone.

"It's a tad excessive," RCMP spokesperson Sgt. Paul Manaigre said.

​While dangerous driving charges aren't anticipated, Manaigre said Manitoba has reciprocity agreements with many states including North Dakota, meaning the driver's licence or insurance could be affected back at home.

"It doesn't surprise me," Manaigre told CBC. "I've been policing the Emerson detachment for close to 15 years, so I've caught quite a few speeders ... coming over from the States. You don't see it often, but it does occur."
