Vehicle Code Section 23152

Vehicle Code Section 23152 of California law states that it is illegal for a person to drive a vehicle while under the influence of alcohol or drugs to the point that their ability to operate safely is impaired. This includes having a blood alcohol concentration of 0.08% or higher for adults over 21, or being under the influence of any impairing substance regardless of BAC for younger or commercial drivers. Violating this law can result in criminal penalties, including fines, license suspension, or even jail, depending on the circumstances and prior offenses.
