The parallel parking wasn't on the street - it was in a parking lot (which is partially responsible for me failing the test the first time; if I'd been on the street I would have used my turn signals when parallel parking. Since no one else was allowed in the parking lot I was in, I forgot that time. The second time around I was careful not to do that.

No, Pennsylvania doesn't have any annoying rules regarding who I can carry as passengers. Of course, it will be nearly a month before I have access to a car again anyway, so it isn't really as if it matters.
