<human>: Okay so we live in BC. Legal drinking age is 19.

My sister (18) was driving my mums Ford Explorer. Her boyfriend (19) was in the passengers seat. She was driving a couple friends (too many people for her license, so she got a ticket for that. blah blah blah)

ANYWHO.

Her boyfriend had a thing of alcohol that was opened. He had it in his backpack, which was in the back of the truck (out of reaching distance for any of them).  Well, the cop searched through his backpack, found the alcohol, and made him pour it all out on the side of the road. The cop gave them both a breathalyzer (which came back cleared). He gave her boyfriend a ticket for over $200, and the cop had said that HE was the driver!!

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Open alcohol, in backpack, in back of truck. Cop gave the passenger a ticket, and said that he was driving.
