According to the Pennsylvania's Department of Transportation (PennDot) point system pamphlet, they assign 3 points for violations concerning licenses, your your ticket might fall under this category. Since your exact violation was not listed on this document you should probably contact the Pennsylvania Driver and Motor Vehicle Services to find out for certain if it is a points offense or not.

If the ticket you received was for permitting an unauthorized person to drive your vehicle, you have violated PA vehicle code 1574. This vehicle code states that no person shall authorize or permit a motor vehicle owned by him or under his control to be driven upon the highway by any person who is not authorized to drive or is not licensed for the type or class of vehicle to be driven.

The penalty for violating this vehicle code is a summary offense and the person shall be jointly and severally liable with the driver for any damages caused by the negligence of the driver while operating the vehicle.
