Preliminary figures from the Minnesota Department of Public Safety show more than 500 motorists were arrested on DWI charges between 5:30 p.m. on July 3 through July 7.
According to numbers released Monday, 225 of the arrests occurred between July 3-4. The remaining 335 took place from July 5-7.
DWI patrols were increased in the Twin Cities area during the holiday period because July 4 is historically the state's deadliest day of the year on the roads, with 19 deaths from 2008 to 2012. This year, three motorcyclists were killed in two separate crashes.
Five people were killed over the holiday weekend in all, including one who died in a Clay County rollover and a bicyclist struck by a hit-and-run driver in Minneapolis.
Drunken driving is a major factor in deaths over the Fourth of July holiday, with 65 percent of traffic fatalities linked to alcohol consumption. Minnesota's annual percentage of road deaths resulting from drunken driving is historically around 30 percent.
In the past five years, 19 of the 29 road deaths during the official holiday travel period were drunk-driving related.
THE CONSEQUENCES OF DWI
A DWI offense can cost thousands in fines, result in losing a driver's license for up to a year, and can also include jail time.
Both first-time and repeat offenders with a blood-alcohol content of .16 or higher are required to use ignition interlock devices to regain their driving privileges. Offenders with three or more DWIs on their record will be required to use the interlock device for 3 to 6 years or lose their driver's license permanently.
