When the "safe corridor" box is checked on a New Jersey traffic ticket it means that your fine amount will be doubled but to the relief of you and many other drivers, points are not doubled. And no, the points will not be transferred over to Pennsylvania.
In 2004 the state of New Jersey initiated the Safe Corridors Program in an effort to improve highway safety. The Safe Corridors law, New Jersey Statutes Annotated (NJSA) 39:4-203.5, doubles fines on various NJ highways for a variety of driving offenses, including speeding and aggressive driving.
It would appear that you were ticketed under NJSA 39:4-98 Safe Corridor, Construction Zone or 65 MPH area, speeding and exceeding limit by 15 - 19 mph which on the fine list we last saw came with a fine of $176. You will have to contact the court on your ticket to find out the fine amount you will have to pay if you plead guilty to this offense.
In New Jersey speeding 15 to 29 mph over the limit in New Jersey is 4 points. Since you do not live in NJ but instead in Pennsylvania you are in luck and will end up with no points there for this out-of-state traffic ticket.
New Jersey and Pennsylvania are both part of the Driver License Compact (DLC) so if you pay the speeding ticket and thus are convicted of it the NJ courts will report the violation to the Pennsylvania Department of Transportation (PennDOT).
PennDOT and the PA Driver and Vehicle Services say that they do not record most minor out of state violations, such as your speeding ticket, on your PA motor vehicle record (MVR) or assign points for these violations. So in your home state of Pennsylvania you will not receive points or even have the New Jersey speeding in a safe corridor violation listed on your driving record.
Without the out-of state offense being posted onto your MVR for your auto insurance company to see, it should not affect your car insurance rates. Use CarInsurance.com when shopping around for affordable auto insurance rates in Pennsylvania; even if your rates are not affected by the NJ ticket you may still find cheaper insurance then what you currently pay.
