LOS ANGELES (CNS) - The annual Avoid the 100 winter holiday crackdown on  intoxicated driving in Los AngelesCounty resulted in nearly 500 DUI arrests  over the weekend, authorities said today.

There were 495 motorists arrested on suspicion of driving under the  influence of alcohol and/or drugs between 12:01 a.m. Friday and Sunday  in the county, authorities said. During the same period a year ago, there were  456 DUI arrests in the county.

The Avoid the 100 campaign will include dozens of sobriety/driver's  license checkpoints and more than 200 ``roving DUI saturation patrols'' in  various areas of the county, and will continue through New Year's Day.

``Our task  force will be highly visible during this enforcement period,  and those suspected of driving while intoxicated will be shown zero tolerance  if they are over the limit,'' said Glendora Police Chief Rob Castro.

Castro urged people to use a designated driver or public transportation  if they have been drinking.
