I didn't know this... As a non-Illinois resident who holds a non-reciprocal CCW and travels to and through Illinois for business, without an FOID card...at the Illinois state line, I unloaded my firearm and locked it up, and locked up the ammunition separately. Turns out this isn't necessary. Nothing in this Act shall prohibit a non-resident from transporting a concealed firearm within his or her vehicle in Illinois, if the concealed firearm remains within his or her vehicle and the non-resident: (1) is not prohibited from owning or possessing a firearm under federal law; (2) is eligible to carry a firearm in public under the laws of his or her state or territory of residence; and (3) is not in possession of a license under this Act. If the non-resident leaves his or her vehicle unattended, he or she shall store the firearm within a locked vehicle or locked container within the vehicle in accordance with subsection (b) of Section 65 of this Act. Public Act 0063 98TH GENERAL ASSEMBLY That's section 40(e). But, it's best to print the entire act out if you're planning on using it. Having a copy of the Firearm Owners Protection Act "Safe Passage" provision...codified in section 926A of title 18 of the U.S. Code. Since I will never set foot in the Northeast or the West Coast states, that leaves Minnesota and Nevada for me. Hardly ever travel to either...but Illinois is impossible for me to avoid.
