Final answer:
A driver aged 19 or under in the first 6 months of their G2 license is allowed to carry one passenger aged 19 or under between 12-5am.
Step-by-step explanation:
If you are a driver aged 19 or under and within the first 6 months of receiving your G2 license in Ontario, Canada, you are allowed to carry one passenger aged 19 or under between 12-5am. This limitation is part of the graduated licensing system designed to reduce the risks for new drivers. After the first 6 months, or if you are driving with a full-G licensed driver of at least four years of driving experience in the front passenger seat, this limitation is increased to three passengers aged 19 or under.
