Asked in State Laws
What is the state of Connecticut's consequences for underage drinking if you have a permit?
To parse your question, one can assume that you're drinking
alcohol while underage.
One can also assume that you have a permit to drive a car, since no permit is required by age, to drink alcohol.
According to the Connecticut State Police Web site, their motto is "Underage = Under Arrest."
Apparently, depending on what you're doing when you are caught drinking when you are under the legal age to consume, the police can charge you with at least underage drinking.
If you're drinking and operating an automobile, the consequences can be serious, depending on the officer who catches you.
Whoever is responsible for teaching you how to drink has or will surely teach you that once you begin drinking you must not drive a car. The two are mutually exclusive.
