Can a minor get in trouble for riding in a car with unopened alcohol?

Yes. A passenger under 21 breaks California law by knowingly possessing or controlling any alcohol in a vehicle, even a sealed, unopened container, and a driver under 21 breaks it by knowingly driving a vehicle that is carrying any alcohol. This rule is separate from, and stricter than, the state’s general open-container laws, and it carries its own fine, a possible vehicle impound, and a driver’s license suspension.

The rule applies to drivers and passengers separately

Vehicle Code section 23224 has two parts. Subdivision (a) says no person under 21 “shall knowingly drive any motor vehicle carrying any alcoholic beverage.” Subdivision (b) separately bars a passenger under 21 from knowingly possessing any alcoholic beverage or having one “under that person’s control.” For a passenger, the question is whether they knowingly possessed or controlled the alcohol, not simply whether it was somewhere in the car. Neither subdivision distinguishes between an open container and a sealed one. The general open-container rule for drivers and passengers, Vehicle Code section 23223, reaches only a container that has been opened, has a broken seal, or has been partly emptied.

Section 23224 also names no particular place. It sits in a chapter of the Vehicle Code whose provisions apply “upon the highways and elsewhere throughout the State unless expressly provided otherwise” (Vehicle Code section 23100), and nothing in section 23224 provides otherwise. Section 23223, by contrast, is written for a vehicle on a highway or on the off-highway vehicle lands described in Vehicle Code section 23220.

The exceptions, and the one built-in defense

Both the driver and the passenger rule share the same two exceptions. There is no violation if the person is accompanied by a parent, legal guardian, responsible adult relative, or another adult designated by the parent or guardian, for the purpose of transporting the alcohol. There is also no violation if the person is employed by a licensee under the Alcoholic Beverage Control Act and the driving or possession happens during regular work hours in the course of that job. If the minor was unaccompanied and neither exception applies, the statute still gives a complete defense where the minor was “following, in a timely manner, the reasonable instructions” of a parent, legal guardian, responsible adult relative, or adult designee about disposing of the alcohol.

Section 23224 has no trunk exception. The general storage rule in Vehicle Code section 23225 treats an opened container kept in the trunk as properly stored, but section 23224 makes no exception based on where in the vehicle the alcohol is kept.

The penalty, and when the vehicle itself is at risk

A conviction under either subdivision (a) or (b) is a misdemeanor. The statute sets the penalty at a fine of “not more than one thousand dollars ($1,000),” up to six months in county jail, or both. Separately, if the vehicle used in the violation is registered to an offender who is under 21, the vehicle “may be impounded at the owner’s expense for not less than one day nor more than 30 days for each violation.” That impound provision depends on who owns the car: if the vehicle is registered to a parent or someone else rather than the under-21 offender, this specific impound rule does not apply.

The license consequence that is not written into this statute

A conviction under section 23224 also triggers a mandatory driver’s license suspension, even though that consequence appears nowhere in section 23224 itself. Vehicle Code section 13202.5 requires a court to suspend the license of anyone convicted of a listed offense committed while they were 13 to 20 years old, and one of the categories it lists is “Article 2 (commencing with Section 23152) of Chapter 12 of Division 11” of the Vehicle Code. Section 23224 is chaptered inside that same article, which spans sections 23152 through 23229.1, so a 23224 conviction falls within the suspension list even though the two statutes are not cross-referenced by section number. Under this section, a finding made in a juvenile proceeding is treated the same as a conviction.

For a qualifying conviction, the court must suspend the license for one year, or, if the person is not yet licensed, order a one-year delay after they become eligible, with an additional year for each further qualifying conviction. If there is no further qualifying conviction within 12 months, the court may modify a delay order on petition. A person whose privilege was suspended or delayed can also ask the court to review the order and permit limited driving on a showing of “a critical need to drive.”

How this differs from an ordinary open-container stop or a DUI

Keeping the bottle sealed does not prevent a violation for anyone under 21, because section 23224 drops the open-versus-closed distinction entirely, and keeping it out of reach does not help a driver under 21 whose car is carrying it. It is also a different question from a DUI charge: section 23224 applies whether or not anyone was impaired. Impaired driving under 21 raises separate rules, covered in our underage DUI overview.

What this means in practice

If a minor is stopped with alcohol anywhere in the vehicle, the facts that decide the fine, the impound, and the license consequence are who knew about the alcohol and who had control of it, whether an accompanying adult qualifies for the exception, and who the car is registered to.

If a minor in your family was cited under this section, the vehicle’s registration and the stop itself are worth a careful look. The Law Offices of David S. Chesley can go through both with you at (800) 755-5174.
