Can I carry alcohol in my car?
It is unlawful for an underage person to have alcohol in their possession.
The only exception is if you work in an establishment that serves alcohol. You can transport it only in connection with your work.
You do not want to have a discussion with the police about actual or constructive control of an alcoholic beverage. Nor do you want to be before a judge or the college administration.
Best not to carry alcohol in any form in your car.
It does not matter if the container is open or closed.
