Underage DUI
Under California VC 23136, it is a civil offense for a driver below the age of 21 years to operate a vehicle with a blood alcohol concentration of 0.01% or more. This statute outlines California’s zero-tolerance laws for juvenile drivers. Underage DUI charges can result from consuming any beverage that contains alcohol, including mouthwash, and not just alcoholic drinks. Even certain medications that contain alcohol can lead to underage DUI charges. The charges can apply even if the driver’s abilities were not impaired by alcohol. Having a measurable alcohol content in the blood is enough to lead to underage DUI charges.
A violation of underage DUI laws under VC 23136 is considered a civil offense, not a criminal one. The punishment for violating this statute is a mandatory suspension of your driver’s license. A first offense attracts a one-year license suspension. Drivers with a history of violating the California drunk driving laws can have their licenses revoked for two to three years, but this depends on the severity of prior offenses.
For underage drivers, the police administer a preliminary alcohol screening (PAS) test. This roadside test is performed on a breathalyzer or similar equipment that measures the alcohol in a driver’s breath.
Underage drivers can also face charges under VC 23140 for driving with a BAC of 0.05% or higher. A post-arrest DUI chemical test follows an arrest for a violation of this statute. The post-arrest test can be a breath test performed at the police station or a DUI blood test. Violating California VC 23140 is a low-level crime that will not result in jail time. The potential penalties include a license suspension for up to one year for a first offense. A first offense can also attract a fine of up to $100. Drivers above 18 years could be subject to a compulsory alcohol education program for three months or more.
