<p>If somebody else in the car is carrying drugs and something happens, your kid may also be arrested. This will not occur if somebody else on the bus is carrying drugs. Of course, your decisions will be informed by your own experience…in my case, it was in the middle of the night, freezing cold, somewhere on the interstate, when I realized that the driver had pot in the car. I didn’t bail out early–although I should have. I would only let my kids take a ride from somebody they already know, and even then I would have questions…I would never have them accept a ride from a young driver just to save money.</p>
