In 2013, 844 people died on state and local highways and streets, up 2.8 percent from the 2012 total of 821, ADOT said.
Those numbers are well below the highest annual death rate, recorded in 2006, which was 1,301.
Overall, ADOT listed a total of 107,348 crashes of all types for 2013, up 3.3 percent from 2012.
The most common driver violation cited by police officer was "speed too fast for conditions."
Alcohol-related fatalities dropped by more than 7 percent last year compared to 2012. In 2013, 262 people were killed in alcohol-related crashes, ADOT reported.
The total number of reported alcohol-related crashes was down from 5,460 in 2012 to 5,190 in 2013.
"The decrease in alcohol-related crashes and deaths is welcome news but doesn't change our mission to stop impaired driving," Governor's Office of Highway Safety Director Alberto Gutier said. "Whether it's our tougher laws, stepped up law enforcement or public awareness campaigns, we have to keep up the battle because nearly a third of the fatal crashes in the state last year were alcohol-related."
Friday was the peak day of the week for crashes in 2013, and the single worst day was November 22, with 737 reported, ADOT said.
