All of the states in the top five except Wyoming were also on the top five list in 2016. On the upside, every state in the five worst except of Wyoming decreased its rate of drunk driving deaths year over year in 2017.

Montana is the state that has shown the most impressive improvement overall. It went from ranking first in the nation for most dangerous roads, with 9.58 drunk driving fatalities in 2016, to number 27 with 5.33 lost lives in 2017.

The report, which draws on the most recent impaired driving data from the National Highway Traffic Safety Administration (NHTSA), was released to coincide with the holiday season.

History shows that the winter holidays bring with them an uptick in drunk driving, with New Year's Eve ranking among the deadliest nights on the nation's roads.  

In fact, drunk driving deaths increased by 35% between Thanksgiving Eve and New Year's Eve from 2013 to 2017, according to NHTSA data. In 2017, 1,143 people were killed from 6 p.m. Thanksgiving Eve through New Year's Eve.
