Under existing law, if a person is convicted of either driving under the influence (DUI) of any alcoholic beverage or drug, or under the combined influence of any alcoholic beverage and drug or driving while having 0.08% or more, by weight, of alcohol in the person's blood within 10 years of 2 separate violations of specified DUI offenses, or any combination thereof, that resulted in convictions, that person has committed an offense punishable by imprisonment in the county jail for not less than 120 days nor more than one year and by a fine, as specified. This bill would, instead, make the above DUI conviction punishable as a wobbler by imprisonment in the county jail for not less than 120 days nor more than one year and by a fine, as specified, or by imprisonment in the county jail for 16 months or 2 or 3 years and a fine, as specified. By increasing the punishment of a crime, this bill would impose a state-mandated local program. Under existing law, if a person is convicted of DUI and the offense occurred within 10 years of 3 or more separate violations for driving under the influence that resulted in specified convictions, that person has committed an offense punishable as either a misdemeanor or a felony. This bill would, instead, make the above DUI conviction punishable as a wobbler if the offense occurred within 10 years of 3 separate violations for driving under the influence that resulted in specified convictions, and punishable as a felony by imprisonment in the county jail for 16 months or 2 or 3 years and a fine, as specified, if the offense occurred within 10 years of 4 or more separate violations for driving under the influence that resulted in specified convictions. By increasing the punishment of a crime, this bill would impose a state-mandated local program. This bill would make conforming changes. This bill would incorporate additional changes to Sections 23546, 23550, and 23550.5 of the Vehicle Code proposed by AB 1830 to be operative only if this bill and AB 1830 are enacted and this bill is enacted last. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
