What would happen if you got pulled over with a permit?
telo118 [61]
Not sure what this has to do with social studies, but as long as you had an adult over the age of 21 with a  license in the car it would proceed like normal. If you didn't, which is illegal, you'd probably end up going to the police station, would no longer have a permit, and might not be able to get a license until you're 18-21. Don't do it please.
