The northwest region of North Dakota accounted for more than half of the fatal crashes in the state last year.
McKenzie County had 22 fatal crashes in 2013.
Before the oil boom started, the county would have maybe two or three a year.
Department of Transportation Director Grant Levi says the state has benefited from the energy boom, but the result has been more traffic.
The numbers are also up this year... Of 26 fatal crashes through April 25, 15 occurred in the northwest region of the state.
