Children of all ages will be out in costume Saturday night celebrating one of the most revered holidays of a youngster's life — Halloween.
Police officers throughout the Bay Area also will be out that night, watching for ghouls who could spoil the holiday by driving while intoxicated.
Law enforcement agencies will be on high alert all weekend, starting Friday, looking for drunken drivers.
Officers in select cities, including Fremont and Hayward, will provide extra patrols with the sole purpose of keeping intoxicated drivers off the road.
Because the holiday is on a weekend, authorities think that adult partygoers may indulge in alcohol and try to drive home.
"With Halloween falling on a Saturday this year, we want to make sure revelers aren't taking the party to the roadways, putting trick-of-treaters and responsible motorists at risk," Hayward police Sgt. Jeff Lutzinger said.
He added that Halloween has been one of the most deadly nights in recent years nationwide, due in part to drunken motorists.
More than 450 people have been killed on California roads in alcohol-related crashes during the past five Halloween nights, he said.
A few ways to avoid police on Halloween is to designate a sober driver for the evening, or take a cab, police said.
AAA of Northern California is offering another solution with its free "Tipsy Tow" program.
If a motorist feels too intoxicated to drive, AAA will give him or her a free ride and tow up to five miles to their home, even if they are not a member of the organization.
"Everybody wants to enjoy their costume parties this Halloween weekend, but if you've been drinking, don't be a joker and get behind the wheel," AAA spokesman Matt Skryja said.
"Instead, be a super hero and give AAA a call."
