Having an open alcoholic beverage inside a vehicle can cause legal trouble even if you are not driving under the influence. Pennsylvania restricts possession of open alcohol containers and alcohol consumption in motor vehicles on its highways.
Pennsylvania open container law applies to both drivers and passengers, although there are specific exceptions. An open container can also attract additional attention during a traffic stop and potentially lead to a DUI investigation.
Open container laws apply to drivers and passengers
Pennsylvania law generally prohibits an operator or occupant from possessing an open alcoholic beverage container in a motor vehicle while the vehicle is on a highway. It also prohibits drinking alcohol inside the vehicle under these circumstances.
Because the restriction applies to occupants, you do not have to be the driver to face an open container charge. A passenger holding or drinking from an open alcoholic beverage container can also violate the law. A violation is treated as a summary offense.
However, Pennsylvania provides limited exceptions for certain passengers. The restriction does not apply to a passenger in the passenger area of a vehicle primarily designed, maintained or used for the lawful transportation of people for compensation. This includes passengers in buses, taxis and limousines.
Another exception applies to an individual inside the living quarters of a house coach or house trailer. These exceptions depend on the type of vehicle and where the person is located. Being a passenger in an ordinary private vehicle does not create the same exception.
An open container charge is also separate from a DUI charge. Finding an open bottle or another alcoholic beverage inside a vehicle does not by itself establish that the driver was impaired.
However, an open container discovered during a traffic stop may cause police to investigate whether the driver has consumed alcohol. Driving behavior, observations made during the stop and alcohol testing may then become relevant to DUI defense in Pennsylvania.
If you face an open container charge or related DUI allegations, seek legal guidance to understand how Pennsylvania law applies to the circumstances of the traffic stop and the evidence involved.
