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

S 1871 establishes a "reasonableness standard" for individuals lawfully transporting firearms who deviate from their normal travel route. It applies to specific exempted groups, including law enforcement officers, correctional officers, and others authorized to carry firearms for official duties under New Jersey law. The bill clarifies that such deviations (e.g., unexpected detours for job-related reasons) do not violate firearm transportation laws if the deviation is reasonable. This amendment aims to prevent legal penalties for minor, necessary route changes during lawful firearm transport, without expanding existing exemptions.
