More than 1,900 people have been arrested in the Bay Area for driving under the influence of alcohol or drugs during a regional anti-DUI crackdown that started last month and ends today.

The regional Avoid campaign, which involves 125 Bay Area law enforcement agencies, had netted 1,960 arrests through 6 a.m. Saturday, according to officials.

The increased enforcement efforts began Dec. 18.

The arrest numbers are provisional, since a number of agencies have not yet reported their statistics.

Last year, the winter holiday Avoid campaign netted 3,261 arrests in the Bay Area.

There were five DUI-involved fatal collisions in the region during the 2008 enforcement period, while there have been two so far this year.
