Each step is its own page, with the Illinois figures read from the agency that publishes them.

How Illinois organizes trucking compliance
Four agencies split the job, and none of them hands off to the next. The Illinois Commerce Commission licenses intrastate for-hire property carriers and sells the yearly cab card. The Department of Transportation issues oversize and overweight permits. The Department of Revenue administers fuel tax as the Motor Fuel Use Tax. The Secretary of State registers apportioned fleets through its Commercial and Farm Truck Division.
That means four accounts and four separate clocks. Permits run through the state's automated permit system, fuel tax runs through the state tax portal, the certificate is applied for at the Commission, and apportioned plates are filed on paper with the Secretary of State inside a fixed autumn window. Each Illinois page here tells you which agency owns the step you are on.
What you will find here
The intrastate authority page owns the Public Carrier Certificate answer: who needs it, the fee table, the insurance grid by commodity, and the cab card that recurs every year. The permits pages cover legal size and weight limits by highway class, single-trip and blanket permit pricing, escorts, and the movement windows that shrink around Chicago. The fuel tax and apportioned registration pages cover base-state licensing, quarterly returns, and how Illinois computes an apportioned fee.
Every figure on those pages is a stored field tied to the agency page or statute section it was read in. Where Illinois publishes nothing, we say so and leave the field empty rather than filling it with a number from somewhere else.

Frequently asked questions
Does Illinois require its own operating authority?
Yes. Hauling property for hire inside Illinois takes a Public Carrier Certificate from the Illinois Commerce Commission. The trigger is the activity rather than the truck's weight: for-hire transportation of property over public roads in intrastate commerce. Holding federal interstate authority does not substitute for it.
Which agencies handle trucking compliance in Illinois?
The Commerce Commission for intrastate authority and cab cards, the Department of Transportation for oversize and overweight permits, the Department of Revenue for fuel tax, and the Secretary of State for apportioned registration. Plan on a separate account and a separate renewal date with each one.
Do I need a USDOT number before the Illinois paperwork?
Not for the certificate itself. The Commission's application asks whether you hold a USDOT number but does not require one, and Illinois only pulls the federal identification rule onto an intrastate carrier that needs a hazardous materials safety permit. The fuel tax license is the step that does require one.
Where do the numbers on these Illinois pages come from?
Each one is a stored field tied to the agency page or statute section it was read in, with a source marker you can open. Where an agency states an amount but attributes it to a rule we did not read, the field says so. Anything Illinois leaves unpublished stays empty and labeled.
