WAUSAU, Wis (WSAU) For the second time this year Wausau police set up an alcohol enforcement zone within the city.

Grand Avenue between downtown and the Schofield city line was targeted. On Saturday night police added extra patrols, and pulled over drivers for any and all vehicle violations. Drivers who said they'd been drinking or showed signs of intoxication were given field sobriety tests.

The finding for the extra patrols were made possible by state and federal grants.

In Wisconsin, sobriety checkpoints where all vehicles are stopped are not allowed under state law. But enhanced enforcement and screening of drivers who've already been pulled over for other infractions is.
