I've heard that it's okay to have a sibling in the car if you "have a note". I've also heard this is not legal and the police, when caught, will make the sibling get out of the car and walk and he will ticket the driver.
Further, I think a lot of parents "look the other way" when their child is actually driving friends and siblings around during this first year which makes it tough for the rest of us parents that are trying to go by the rules.
What are the real laws (I know what DMV says) and how strict are they around Pleasanton? I don't want to be the only one enforcing them.
