Half of the state's 113 motor vehicle deaths in 2016 involved alcohol, according to a National Highway Traffic Safety Administration report. The national average is 28 percent.
A national organization, Safewise, is aiming to reduce the number of drinking and driving fatalities and is offering free gift cards to Lyft users in North Dakota.
In North Dakota, in 36 percent of fatal crashes a driver had a blood alcohol content over 0.15, nearly double the legal limit, the report said.
The country spent nearly $44 billion related to alcohol-impaired crashes during 2010, including workplace losses, medical costs and property damage, according to the study. There were 10,496 fatalities in which drivers had a BAC over 0.08 in 2016.
Safewise is giving away Lyft gift cards for Labor Day weekend to the first 100 people from Montana, South Carolina, North Dakota, New Mexico and Alabama.
