Establishes reasonableness standard for persons lawfully transporting firearm who deviate from course of travel.

This bill establishes a "reasonableness standard" for individuals lawfully transporting firearms under existing exemptions (such as police officers, security personnel, or others permitted to carry firearms for specific duties) when they deviate from their intended travel route. It requires that any deviation must be reasonable and necessary, such as for an emergency stop or legitimate purpose, rather than arbitrary. The standard applies to all current exemptions in New Jersey law and does not change who is permitted to carry firearms for their job. The bill clarifies when a detour during lawful firearm transport remains compliant with state law.
