Illinois expanded-use antique plates let you drive a vehicle that is more than 25 years old on public roads with no purpose restrictions from March 1 through November 30, and limit you to auto shows, exhibitions, servicing, and demonstrations the rest of the year. The plates are authorized by 625 ILCS 5/3-804.01 and carry a $45 annual surcharge on top of standard registration fees.1Illinois General Assembly. 625 ILCS 5/3-804.01 – Expanded-Use Antique Vehicles
When You Can Drive an Expanded-Use Antique Vehicle
The nine-month unrestricted window runs from March 1 through November 30. During those months, there is no restriction on why you drive the car. Commuting, errands, weekend trips, a long haul across the state — all fine. The statute sets no mileage cap.
From December 1 through the last day of February, the car reverts to show-and-service use only. You can drive it to and from antique auto shows, exhibitions, servicing appointments, and demonstrations, and nothing else.1Illinois General Assembly. 625 ILCS 5/3-804.01 – Expanded-Use Antique Vehicles A run to the mechanic or a restoration shop counts as servicing, so winter maintenance trips are covered. A grocery run is not.
The statute makes no exception for club drives, educational events, or school demonstrations that fall outside the four listed categories. If a winter trip doesn’t fit show, exhibition, servicing, or demonstration, it isn’t authorized.
Eligibility
The vehicle must be more than 25 years old. Bona fide replicas of vehicles more than 25 years old also qualify, even when the replica itself was built recently. Firefighting vehicles need only be more than 20 years old.1Illinois General Assembly. 625 ILCS 5/3-804.01 – Expanded-Use Antique Vehicles
When you apply, you affirm that the vehicle’s mechanical condition, brakes, lights, glass, and overall appearance are the same as originally equipped or at least equally safe. The car doesn’t need to be a museum piece, but modifications that compromise the original safety equipment or drastically change the vehicle’s appearance can cause problems at registration. The statute doesn’t require photographs or a physical inspection, though the Secretary of State’s office may ask for additional documentation.
Fees
Expanded-use antique plates carry a statutory surcharge of $45 per year on top of standard registration and renewal fees. Motorcycles registered as expanded-use antiques pay a reduced surcharge of $23 per year.1Illinois General Assembly. 625 ILCS 5/3-804.01 – Expanded-Use Antique Vehicles
If you currently hold standard antique plates and want to move to expanded-use, the Secretary of State may credit a pro-rated portion of your previously paid antique registration fee toward the new plate.
How Expanded-Use Differs From Standard Antique Plates
Illinois runs two separate antique plate programs, and they are often confused. Standard antique plates under 625 ILCS 5/3-804 are cheaper — $24 for 2026, with an expiration date of December 31, 2029 — but the show-and-service restriction applies all 12 months of the year with no unrestricted season.2Illinois Secretary of State. Antique License Plates3Illinois General Assembly. 625 ILCS 5/3-804 – Antique Vehicles Personalized standard antique plates cost $124 for the first issuance and $43 to renew.
Standard plates make sense for a car that only leaves the garage on a trailer bound for a show. If you want to actually drive the car with any regularity, expanded-use is the plate to ask for.
Using Year-of-Manufacture Plates
You can bolt an original Illinois-issued license plate matching the vehicle’s model year onto an expanded-use antique car in place of the current plates. The catch: the valid current antique plates and the registration card must be inside the vehicle and available for inspection at all times.3Illinois General Assembly. 625 ILCS 5/3-804 – Antique Vehicles Keep them in the glove box. A vintage plate alone will not satisfy an officer at a traffic stop.
Insurance
An expanded-use antique vehicle must carry the same minimum liability coverage as any other registered vehicle in Illinois: at least $25,000 per person and $50,000 per accident for bodily injury, plus $20,000 for property damage.4Illinois Department of Insurance. Auto Insurance Shopping Guide There is no antique exemption.
Most collectors use a specialty carrier rather than a standard auto insurer. Collector policies commonly offer agreed-value coverage, paying a pre-set appraised amount rather than depreciated book value, and tend to cost less because the insurer assumes limited use. Many specialty carriers cap annual mileage at 2,500 to 5,000 miles, require garage storage, and require that you own a separate daily-driver vehicle. Those private policy terms can be tighter than what state law requires, so a car legally free to drive under expanded-use rules from March through November may still be limited by its insurance contract.
Proof of insurance must be in the vehicle. Driving without insurance can bring fines and suspension of the plates.
Safety Equipment and Emissions
Illinois requires that the vehicle’s brakes, lights, and glass remain as safe as originally equipped. You don’t have to retrofit modern features, but whatever the car came with from the factory must still work.1Illinois General Assembly. 625 ILCS 5/3-804.01 – Expanded-Use Antique Vehicles
Vehicles with a model year before 1965 are exempt from the Illinois seat belt requirement. Neither driver nor passengers are legally required to buckle up in those cars, though wearing available belts is still safer.5Illinois General Assembly. 625 ILCS 5/12-603.1 – Seat Belt Requirements
Illinois emissions testing applies to most 1996 and newer gasoline-powered passenger vehicles once they are more than four years old, and only in certain counties in the Chicago metropolitan area.6Illinois EPA. Vehicle Emissions Testing Program Because expanded-use eligibility requires the vehicle to be more than 25 years old, many qualifying cars predate the 1996 OBD-II cutoff and aren’t subject to testing at all.
What Happens If You Drive Outside the Allowed Purposes
The antique plate statutes don’t set a specific fine schedule for using the vehicle outside the permitted purposes during the winter months. Misuse is a violation of the Illinois Vehicle Code, and officers can issue citations. General Class C misdemeanor penalties under Illinois law allow fines from $75 up to $1,500 and up to 30 days in jail.7Illinois General Assembly. 730 ILCS 5/5-4.5-65 – Class C Misdemeanor Repeated violations could lead the Secretary of State to revoke the antique registration, though the statutes do not spell out automatic escalation.
The practical exposure is narrow but real. If an officer spots your antique-plated car at a grocery store in January and you can’t tie the trip to a show, exhibition, servicing, or demonstration, you are open to a citation. From March 1 through November 30, this isn’t a concern.
