This year, state troopers have arrested 125 drunk drivers in the Tri-Cities and Yakima areas.
That's nearly double the arrests from a year ago.
Troopers beefed up drunk driving patrols after an increase of crashes.
Since then, the number of DUI wrecks have dropped 60%.
Not surprisingly, more arrests happen late at night.
More than 80% of all cases happen after 10 pm.
