Quick Answer
In Illinois, you must have an Illinois CCL to carry a loaded handgun in your motor vehicle. If you are a non-resident with a permit from your home state, you may keep a loaded handgun in the car while driving through. If you have no permit at all, the handgun must be unloaded and fully enclosed in a case.
The Non-Resident Trap
Illinois does not recognize concealed carry permits from any other state. However, they offer a very specific, easily misunderstood exemption for out-of-state drivers passing through on I-80 or I-55.

The Drive-Through Exception
If you are not an Illinois resident, but you possess a valid carry permit from your home state, you may legally transport a loaded, concealed handgun inside your vehicle while traveling through Illinois.
The Gas Station Catch
Exiting the Vehicle
The moment you step out of your vehicle (even just to pump gas or use a restroom), your home-state permit becomes invalid. You must leave the firearm locked inside the vehicle or inside a locked container within the vehicle, completely out of plain view.
The "Unloaded and Cased" Rule (No Permit)
If you do not have an Illinois CCL, or you are an out-of-state driver without a home-state permit, 720 ILCS 5/24-1(a)(4) dictates your firearm must be completely unloaded and enclosed in a case, firearm carrying box, shipping box, or other container. A glove compartment or center console does legally count as a case under Illinois Supreme Court precedent (People v. Diggins), provided the gun is fully unloaded.
Illinois Safe Harbor Storage
Whether you are a resident parking at a "Gun-Free Zone" or a non-resident stepping out of your car for food, Illinois law demands your unattended firearm be securely locked and hidden. A tethered vehicle safe is your strongest defense against state prosecutors and smash-and-grab thieves in Chicago.

Duty to Inform Law Enforcement
Illinois is an "Upon Demand" state under 430 ILCS 66/20. You are not statutorily required to volunteer your CCL immediately when an officer walks up to your window. However, if an officer explicitly asks if you are carrying a weapon, or if the officer asks you to produce your driver's license, you must disclose your firearm and present your CCL.
