Concerning Pennsylvania law specifically. I know the 'common sense' and spirit of the law answer to this question, but _technically_, is there a chargeable offense for driver or passenger (supervisor) in this situation:
16 year old driver has learners permit, and is operating the vehicle. Supervising parent is in passenger seat, alert, but with a BAC over the legal limit allowed if they were driving.
For reference, I'm looking at:
§ 3802. Driving under influence...
(a) General impairment.--
(1) An individual may not ___drive, operate or be in actual physical
control of the movement of a vehicle__ after imbibing
§ 1505. Learners' permits.
(no verbiage regarding impairment of supervising, licensed driver)
