Colorado’s open container laws make it a traffic infraction to drive while consuming or possessing open containers of alcohol or marijuana.

1. What is driving with an open container in Colorado?

Driving with an open container is when people in the passenger area of a motor vehicle on a public road knowingly consume alcohol or marijuana or have open containers of alcohol or marijuana in their possession. Consumption of alcohol or marijuana while in the vehicle is illegal even if the person is not driving or impaired.

CRS 42-4-1305 defines “open alcoholic beverage container” as “a bottle, can, or receptacle that contains any amount of alcoholic beverage and:

That is open or has a broken seal; or
The contents of which are partially removed.”¹

An alcoholic beverage includes beer, cider, malt liquor, sake, wine, distilled spirits, or similar fermented beverages containing 0.05% alcohol or more by volume.² Even if the booze was consumed in a legal location, such as a restaurant or at home, the uncorked or unsealed bottle or cannot be transported in the passenger area of the vehicle. An open alcohol container should be stored in an inaccessible area, such as the trunk of a car.

Meanwhile, CRS 42-4-1305.5 defines an “open marijuana container” as “a bottle, can, or receptacle or marijuana accessory that contains any amount of marijuana and:

That is open or has a broken seal; or
The contents of which are partially removed; and
There is evidence that marijuana has been consumed in the vehicle.”³

Therefore, driving with an open canister of marijuana does not violate Colorado law unless there is evidence that it has been smoked, inhaled, eaten, or otherwise consumed in the car. This is different from open alcohol container laws – a person can be cited even if there is no evidence that any alcohol was drunk.

The “passenger area” is the area of a vehicle designed to seat the driver and passengers. This includes any area readily accessible to the driver or passenger, including the front seat, back seat, glove compartment, under the seat, side door compartments, or seat-back pockets.

2. What are the exceptions?

There are a number of exceptions to Colorado open container laws. Specifically, the penalties do not apply to:

Passengers in a vehicle used for transportation for compensation, such as a taxi or bus;
Possession in the living quarters of a motor home, house coach, or house trailer; or
Possession in a contained area not normally occupied by a passenger, such as behind the last rear seat of a pickup truck

However, many taxi and bus companies prohibit drinking in their vehicles. And it is always unlawful to consume marijuana outside a private residence, so people caught with marijuana in a taxi or bus could face possession charges.

The “passenger area” is the area of a vehicle designed to seat the driver and passengers while the vehicle is in operation.

3. How does the prosecutor prove I am guilty?

Possession of open containers of alcohol or marijuana in vehicles is not a criminal offense in Colorado. Instead, it is a traffic infraction, punishable by a simple fine.

Traffic infractions have a lower burden of proof compared to criminal charges. The prosecutor only has to prove that the defendant is guilty by a preponderance of the evidence. Specifically, prosecutors have to show that:

The defendant was in the passenger area of a motor vehicle;
The car was on a public highway or the right-of-way of a public highway of Colorado;
The defendant drank an alcoholic beverage, consumed marijuana, or possessed an open alcoholic beverage or marijuana container; and
There was evidence of consumption (only in marijuana cases).
