There is not a driver's ed section on OS for a number of reasons.  Here are two of the more critical ones:  First, the laws are not uniform so an answer from a person in one state can be WRONG for a person in a different state.  Second, drivers ed can be seen as giving licensure training, which (in general) can only be done by a person authorized to do so. 

So getting good answers for drivers ed is not something you will find on OS.
