"Safe Passage" provision
One of the law's provisions was that persons traveling from one place to another cannot be incarcerated for a firearms offense in a state that has strict gun control laws if the traveler is just passing through (short stops for food and gas), provided that the firearms and ammunition are not immediately accessible, that the firearms are unloaded and, in the case of a vehicle without a compartment separate from the driver’s compartment, the firearms are located in a locked container.[7]
Under this provision, someone driving from Virginia to a competition in Vermont with a locked hard case containing an unloaded handgun and a box of ammunition in the trunk could not be prosecuted in New Jersey or New York City for illegal possession of a handgun provided that the individual did not stop in New Jersey or New York for an extended period of time."

Brown, another New York statist idiot.
Not true, he stayed for a few days and had the gun in his possession without a license and broke NY law. The federal law will not help you if you spend the night in NY city. Another case occurred a while ago where a traveler had a layover in NY city airport and his flight got canceled. The airport rebooked his flight for the next day and he took his luggage to a hotel which included a weapon. When he went to check back in the next day, the airline called the police and he was arrested with a felony gun possession. When he sued, the NY courts ruled the federal law did not apply to him because he spent the night with his weapon. If he had remained in the airport, then he would have been protected.
