Illinois farm plate rules require that the truck be used exclusively for the owner’s own agricultural, horticultural, or livestock-raising operations on a not-for-hire basis, cap each owner at five farm trucks (only two of which may exceed 59,500 pounds), and treat any misuse as a Class C misdemeanor that can also cost you the registration itself.1Illinois General Assembly. 625 ILCS 5/3-815 – Flat Weight Tax; Vehicles of the Second Division The fee savings are real, but so are the strings attached.
Who Qualifies
625 ILCS 5/3-815 makes farm registration available for trucks used exclusively in the owner’s own agricultural, horticultural, or livestock-raising operations, not for hire.1Illinois General Assembly. 625 ILCS 5/3-815 – Flat Weight Tax; Vehicles of the Second Division “Exclusively” is the operative word. Illinois does not permit a mix of farm and personal use on the same plate.
One narrow for-hire exception exists: a truck used solely to haul seasonal, fresh, perishable fruits or vegetables from the farm to the point of first processing also qualifies.1Illinois General Assembly. 625 ILCS 5/3-815 – Flat Weight Tax; Vehicles of the Second Division Any other for-hire hauling disqualifies the vehicle.
There is also a fleet cap. Each owner may register no more than five farm trucks, and no more than two of those five may exceed 59,500 pounds gross weight.1Illinois General Assembly. 625 ILCS 5/3-815 – Flat Weight Tax; Vehicles of the Second Division Farmers with larger fleets must put the additional trucks on standard commercial registration.
What the Truck Can and Can’t Be Used For
Legitimate use covers hauling your own crops, livestock, equipment, and supplies. What it does not cover is anything else. Errands in town, a daily commute, a side business, hauling for a neighbor for pay — each one puts the vehicle outside the terms of registration.
There is no mileage-radius restriction built into the farm plate itself. The 150-air-mile limit many farmers hear about comes from the CDL and federal driver qualification rules discussed below, not from the registration statute. A farm-plated truck can legally travel farther than 150 miles from the farm as long as the trip is exclusively agricultural. The practical caution is that distance from the farm tends to invite enforcement questions about whether the trip really qualifies.
Registration Fees by Weight Class
Farm plate fees run from $250 to $1,590 per year, set by 12 weight tiers under 625 ILCS 5/3-815:1Illinois General Assembly. 625 ILCS 5/3-815 – Flat Weight Tax; Vehicles of the Second Division
- 16,000 lbs or less (Class VF): $250
- 16,001–20,000 lbs (Class VG): $326
- 20,001–24,000 lbs (Class VH): $390
- 24,001–28,000 lbs (Class VJ): $478
- 28,001–32,000 lbs (Class VK): $606
- 32,001–36,000 lbs (Class VL): $710
- 36,001–45,000 lbs (Class VP): $910
- 45,001–54,999 lbs (Class VR): $1,126
- 55,000–64,000 lbs (Class VT): $1,302
- 64,001–73,280 lbs (Class VV): $1,390
- 73,281–77,000 lbs (Class VX): $1,450
- 77,001–80,000 lbs (Class VZ): $1,590
The savings are substantial. A standard 55,000–59,500 lb truck pays $1,930 per year, while a comparable farm truck pays $1,302. At 80,000 lbs, the standard rate is $2,890 versus $1,590 on farm plates — a difference of $1,300 a year.1Illinois General Assembly. 625 ILCS 5/3-815 – Flat Weight Tax; Vehicles of the Second Division
CDL and Driver Qualification Exemptions
Farm plates open the door to two related exemptions from commercial driver licensing and federal driver qualification rules. Both have conditions that farm plates alone don’t satisfy.
Farm Vehicle Driver
Under 625 ILCS 5/6-507(c), a driver qualifies for the Farm Vehicle Driver exemption when the vehicle is controlled by a farmer (or a family member or employee), transports farm products, equipment, or supplies to or from the farm, is not operated for hire, and stays within 150 air miles of the farm. For a farm semi-truck, the plate must be a farm plate, the driver must be at least 21, the truck cannot leave Illinois, and any employee driver must be a family member.
Federal rules track the same structure. Under 49 CFR 391.2, qualifying farm vehicle drivers operating straight trucks are exempt from all Part 391 driver qualification requirements, including the medical examiner’s certificate. Drivers of articulated vehicles with a gross combination weight rating of 10,001 pounds or more must still hold a current medical certificate.2Federal Motor Carrier Safety Administration. 49 CFR 391.2 General Exemptions
Covered Farm Vehicle
The federal Covered Farm Vehicle designation is a separate path. A vehicle qualifies when it is controlled and operated by a farmer, family member, or employee; carries farm products, equipment, or supplies; does not haul hazardous materials requiring a placard; and is registered with farm plates. For CFVs over 26,001 lbs traveling interstate, the 150-air-mile limit applies. Within Illinois, that mileage limit does not apply to CFVs.3Illinois General Assembly. 625 ILCS 5/18b-101 – Covered Farm Vehicle
Insurance Minimums
Farm-plated vehicles carry the same minimum liability insurance as any other vehicle on Illinois roads. Under 625 ILCS 5/7-203, that means $25,000 for bodily injury or death to one person, $50,000 for injuries involving two or more people in a single crash, and $20,000 for property damage.4Illinois General Assembly. 625 ILCS 5/7-203 – Illinois Vehicle Code
Those minimums are low for a loaded grain truck. Make sure the policy explicitly covers agricultural use; a standard personal auto policy will not cover a farm truck, and a coverage gap can leave you personally on the hook for damages the insurer refuses to pay.
Federal Heavy Vehicle Use Tax
If a farm truck has a taxable gross weight of 55,000 pounds or more, federal law requires you to file IRS Form 2290 for the Heavy Vehicle Use Tax. Agricultural vehicles that travel 7,500 miles or less during the tax period qualify for a suspended tax, meaning you file the form but owe nothing.5Internal Revenue Service. Instructions for Form 2290 (Rev. July 2026) Most seasonal farm trucks stay well under the threshold. Cross it, and the full tax comes due, so keep mileage logs.
Penalties for Misuse
Using a farm-plated truck for non-agricultural purposes is a criminal offense. Under 625 ILCS 5/3-703, registration violations are a Class C misdemeanor,6Illinois General Assembly. 625 ILCS 5/3-703 – Illinois Vehicle Code which in Illinois carries up to 30 days in jail and a fine of up to $1,500.
The Secretary of State can also revoke a farm truck registration. Once that happens, you cannot operate the truck again until you pay the full standard flat weight tax, which as the fee tiers show runs hundreds or more than a thousand dollars higher per year.1Illinois General Assembly. 625 ILCS 5/3-815 – Flat Weight Tax; Vehicles of the Second Division Revocation also strips the CDL and driver qualification exemptions tied to farm registration.
Overweight violations carry separate penalties under Section 15-113, and the fine under Section 3-401 is calculated from the gap between what you paid and what proper registration would have cost.7Illinois General Assembly. 625 ILCS 5/3-401 – Illinois Vehicle Code An overloaded farm-plated truck carrying a load that doesn’t qualify as farm use is a fast way to draw fines that dwarf whatever the plate saved you.
Enforcement often begins with a traffic stop or weigh station inspection. Officers who work agricultural corridors know what a legitimate farm haul looks like, and a farm-plated truck moving construction materials or making regular deliveries to non-farm businesses invites questions. Keeping crop receipts, delivery tickets, or a farm identification number in the cab can resolve a legitimate stop quickly.
