In California, laws about alcohol crimes and vehicles can be confusing. Many people, for instance, believe that having an open container in a vehicle always leads to a DUI conviction. This is not true, however. An open container violation and a DWI are two different offenses, and they come with different rules, different penalties, and have different legal standards.
Understanding an open container vs. DWI in CA is important. It can help drivers understand their rights and avoid any serious trouble with the law. Knowing how motions to suppress work in CA DWI cases can also be useful.

What Is an Open Container Law in California?
California vehicle code makes it illegal to have an open container of alcohol inside a vehicle. The car can be parked or moving, and it doesn't matter. No open alcohol containers in a car on a public road.
Open container is defined as:
A bottle, can, or cup that has been opened
A bottle with a broken seal
Any alcohol that has been partially consumed
Where Open Containers Are Not Allowed - California Vehicle Code
Open container violation occurs when an open container of alcohol is found in the main seating area of the vehicle. This includes in the driver's seat area, in passenger compartments, in cup holders, and in center consoles.
Open containers may be stored legally in the trunk of a vehicle or possibly in a locked compartment, like a glove box. If there is an SUV involved, an open container can also legally be behind the last row of seats if there is no trunk.
What are DUI Charges in California?
A DUI charge, or driving under the influence, is a more serious charge than an open container violation. A DUI arrest may come when a person is suspected of operating a vehicle while impaired by drugs or alcohol.
In California, a driver can be charged with a DUI if:
Their blood alcohol concentration (BAC) is 0.08% or higher, or
Their ability to drive is affected by alcohol or drugs, even if their BAC is lower
This means that a DUI arrest can occur even if there is no open container in the vehicle.
Key Differences Between Open Container and DUI
Both DUIs and open container offenses involve alcohol, but legally, they are treated very differently.
1. Type of Offense
Open Container: Usually an infraction or minor misdemeanor.
DUI: A criminal offense with more serious consequences, like up to six months, or something more, in jail.
2. Proof Required
Open Container: Police only need to show that there was an open alcoholic beverage in the vehicle.
DUI: Police must prove the driver was impaired or over the legal BAC limit for DUI offenses.
3. Impact on Driving Record
Open Container: May not affect your driving record in a major way
DUI: Can lead to points on your license, suspension, or revocation if you were over the legal limit and driving
4. Penalties
Open Container: Usually a fine and a slap on the wrist
DUI: Fines, license suspension, DUI classes, and possibly jail time
Can You Be Charged With Both California's Open Container and DUI Offenses?
Yes, you can be charged with both open container violation and a DUI at the same time if you drink alcohol, fail a breath or blood test/field sobriety tests, and have an open container of alcohol in your vehicle.
Does an Open Container Mean You Were Drinking?
No. Just because a person has an open container in their vehicle doesn't mean that the driver was drinking nor that the driver is impaired.
There are other possible explanations including:
A passenger opened the container
The container was left in the car earlier
The driver was not aware it was there
However, even if the driver was not drinking, having an open container can still lead to a citation from a law enforcement officer.
What About Passengers?
In California, passengers are also not allowed to have open containers in a vehicle on a public road.
This is different from some other states where passengers are allowed to drink. In California:
Passengers can be cited for having an open container
Drivers can also face issues if alcohol is easily accessible
There are some exceptions, such as:
Passengers in a limousine
Passengers in certain hired vehicles
Special Rules for Young Drivers
Drivers under 21 face stricter rules.
In California:
It is illegal for anyone under 21 to have any alcohol in a vehicle, even if it is unopened
This is often called a “zero tolerance” law
For young drivers, an open container charge can lead to:
Fines
License suspension
Additional penalties
How Police Use Open Containers in DUI Cases
Even though an open container is a separate offense, it can play a big role in a DUI investigation.
If an officer sees an open container, it may:
Give them a reason to investigate further
Lead to field sobriety tests
Support a claim that the driver was drinking
In court, prosecutors may use the open container as evidence to strengthen a DUI case. For more information, top criminal defense lawyers in Sacramento CA may be able to help.
