New York is part of the Drivers License Compact so the department of motor vehicles is likely to find out from New Jersey about the speeding violation. New York State however does not add points to your NYS driver record for an offense you committed in NJ.
So typically there would not be points added to your NY driving record but you should still check with the NYS DMV to find out if this out-of-state speeding offense will affect your probation. During the probationary period of a license in NY if you are convicted of a specific traffic violation, such as speeding, reckless driving or following too closely, the DMV suspends your license for 60 days. The DMV will be able to clarify for you if this includes violations from out of state or not.
