PHOENIX - Arizona highway patrol officers, sheriff's deputies and other law enforcement officers arrested 582 people on suspicion of driving under the influence during the holiday weekend.
State highway safety officials released the statistics Monday.
While there were fewer traffic stops overall compared to last year, more people were arrested for both misdemeanor DUI and extreme DUI, which includes those cases where a suspect's alcohol level is greater than 0.15 percent.
There were also more drug-related DUI arrests, with 103 this year compared to 85 in 2013.
The number of under-21 liquor law citations also jumped substantially this year from 31 to 218.
At Lake Havasu, Mohave County deputies say they nabbed two people who were allegedly operating boats while under the influence and issued 10 boating safety citations over the weekend.
