Alaska State Troopers say 56 people were arrested for driving under the influence during concentrated enforcements over the holidays.

Troopers say of those, 51 were for misdemeanor DUI and the rest were felony DUI arrests.

Trooper spokesperson Megan Peters says the deciding factor in a felony DUI arrest is the driver's history of prior DUI convictions.

Troopers investigated two fatality crashes during the enhanced patrol, which ran from Dec. 13 to Jan. 1. Troopers say the first death came on Dec. 23, when Talkeetna resident Richard Leo and four dogs he was driving with were hit by a shuttle bus.

The second fatality came on Dec. 25, when 65-year-old Denver Hammons of Ninilchik died after being ejected from his car during a vehicle rollover near Anchor Point.

There were an additional 21 injury crashes, and 260 crashes that only involved damage to vehicles.

Troopers in a release also say 64 drivers were charged with driving with a suspended or revoked license.

There were 1,095 tickets issued. Most of those, at 208, were for speeding.
