It depends on the circumstances and the legislation of the country concerned
the driver's license would be suspended.
They would lose there license
The person's license will be suspended or revoked, and they will be subject to criminal prosecution.
As long as your teenager was properly insured and he was not involved in the commission of a crime at the time of the accident, nothing should happen to your teenagers driver license.
their license would be REVOKED.
They would be charged
You will get a ticket for these violations but if you bring them with you to court and they show that you were licensed and insured on the date of the accident, these charges will be dismissed.
That would really be irrelevant. If your licence were to be suspended, the suspension period would likely be over before you were released from incarceration after being arrested for hit and run and leaving the scene of an accident.
They would be charged with leaving the scene of an accident in addition to any other charges regarding the cause. There is no requirement to help the other driver.
If the uninsured driver had the permission of the insured driver to operate the vehicle then NOTHING will happen to the uninsured driver. In fact, in this case he or she is not an uninsured driver at all. The insurance follows the vehicle first, the driver second.

Probably, yes. This answer will discuss two situations related to accidents: 1) if you were involved in the accident and 2) if you just happen to come upon the scene of an accident that already happened. 1) Involved in Accident (Hit & Run or Leaving the Scene of an Accident - Minnesota Statute 169.09, Accidents).The driver of any motor vehicle involved in an accident ... shall immediately stop the vehicle at the scene of the accident, or as close to the scene as possible but shall then return to and in every event shall remain at the scene of the accident, until the driver has fulfilled the requirements of this section as to the giving of information. The stop must be made without unnecessarily obstructing traffic. 2) Discovering an Accident (Good Samaritan Statute - Minnesota Statute 171.50, Driver License Compact). A driver can have his or her license suspended for "failure to stop and render aid in the event of a motor vehicle accident resulting in the death or personal injury of another." -- Article IV, Section (a)(4) As with any legal issue, it is best for you to contact an attorney who understands the laws related to your specific issue.
