The Texas Department of Public Safety has already stepped up DWI patrols for Labor Day.
For the next few weeks, DPS troopers are focusing on high-risk locations where alcohol-related crashes happen most often.
DPS says during Labor Day enforcement last year, troopers made more than 2,000 DWI arrests.
The extra patrols are being paid for by a grant from the Texas Department of Transportation.
The increased enforcement started Aug. 19 and runs through Sept. 5.
