According to the New York new driver's brochure, a motorist with a learner's permit, junior permit or junior license may drive outside of New York State if it is allowable by the laws of the other state(s).
If you drive out of New York, you must obey that state's learner or junior permit and license restrictions that may apply. The NYS DMV suggests that you check with the police or motor vehicle authorities of the states which you plan on visiting in your automobile. There does not appear to be a master list of states in which a NY permit is allowable for driving.
You will need to check with the DMVs to find out specifically if your will need to follow both the restrictions of your home/licensing state of New York and the state in which you are driving through or only the conditions placed on your by New York. We have read that it is only the conditions that NYS placed on you must be adhered to in some states, such as NJ, however we would advise you to double check this information with the Department of Motor Vehicles of New Jersey and any other state you plan to drive in with your NY permit.

The New Jersey Motor Vehicle Commission (MVC) told us a while ago that with a valid learner's permit or license from another state one may legally drive in New Jersey as long as you are driving a vehicle that is titled, registered, inspected, and insured in your home state. The out of state permit holder will be subject to the laws of his home state while driving in NJ.
Since state laws are amended constantly, especially considering graduated licensing programs, we would advise you to check with the NJ Motor Vehicle Commission (MVC) to see what restrictions and conditions you will need to follow while operating a vehicle in New Jersey. So contact the NJ MVC to find out exactly what restrictions or conditions you will have to adhere to while in New Jersey, those of your home state of NY, those of NJ or both. |
