Existing law makes it a crime to operate a vehicle while under the influence of alcohol or drugs, and sets forth the penalties for a violation of these provisions. Existing law requires the driver of a vehicle involved in an accident resulting in injury or death to a person, other than that driver, to immediately stop the vehicle at the scene of the accident and provide specified personal information to the injured person or the occupants of the other vehicle and to any traffic or police officer at the scene of the accident. Existing law makes failing to comply with these requirements a crime, punishable as a misdemeanor for an accident resulting in injury and punishable as a misdemeanor or a felony for an accident resulting in death or serious injury, as defined. This bill would make the above-described violation for an accident resulting injury punishable as a misdemeanor or a felony and would impose an increased felony penalty for the above-described violation for an accident resulting in death or serious injury, if either of those violations occurred within 10 years of a separate driving under the influence, reckless driving, or gross vehicular manslaughter violation, as specified. By increasing the potential time of imprisonment, the bill would impose a state-mandated local program. Existing law requires a person who is convicted of specified crimes related to driving under the influence to be advised by the court of the dangerousness of their actions and that if that behavior in the future results in a person's death, they may be charged with murder. This bill would additionally require this advisement to be given if a person enters a plea to a different or lesser offense, as described. 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. By imposing an increased term of imprisonment, this bill would create a state-mandated local program. This bill would provide that no reimbursement is required by this act for a specified reason.
