When is possession of liquor in a vehicle permissible?

Possession of liquor in a vehicle is permissible for passengers on a charter bus primarily due to the specific laws governing commercial transportation. Many jurisdictions allow the consumption of alcohol on charter buses, as they are considered a form of transportation where drinking is permitted, similar to how alcohol is allowed on some types of public transit and buses designed for party or event transport.

In contrast, the other scenarios outlined do not typically align with the legal allowances for liquor possession in vehicles. For drivers, having an open container would generally violate laws that prohibit drinking and driving. While age is a factor in alcohol possession laws, it does not automatically grant permission to possess liquor in all vehicle scenarios. Packaging is also a key element in many regulations to ensure that open containers are not present in situations like passenger vehicles.
