Lohan Gets 1 Day in Jail on Los Angeles DUI Plea

"If she violates, it really is up to the judge" to determine the specific sentence, Meyers said.

Lohan has until Jan. 18, 2008, to complete her jail time, community service and residential drug-rehabilitation program. She must also show proof of enrollment in the 18-month alcohol-education program required of all second-time drunken-driving offenders by that January date, said Michael Bialys, Los Angeles DUI lawyer.
