Tallahassee, FL (AP) - Preliminary figures show 111 people died on Florida's roads during an 18-day holiday period through Jan. 2.
That was almost double the 60 deaths recorded over an 18-day holiday period a year ago.
Florida Highway Patrol Capt. Mark Brown said officials don't yet have an explanation for the increase.
Law enforcement agencies in Florida and across the nation beefed up traffic enforcement during the holidays both years.
Florida state troopers made 505 arrests for driving under the influence of alcohol and drugs during the most recent campaign dubbed "Drive Sober or Get Pulled Over."
That compares to only 407 a year ago.
Overall traffic citations issued by troopers, though, dropped from 40,000 to 35,000.
