Illinois CDL Testing Locations and How They Work

Illinois does not run its own CDL testing sites. Instead, the state contracts with third-party examiners — private companies and organizations — to administer the written and skills tests at locations across the state. You cannot test at a Secretary of State office. You must find an approved examiner, schedule directly with them, and pay their fee.

The Secretary of State maintains a list of all approved CDL examiners on its website, organized by county. Each examiner sets their own hours, fees, and appointment availability. Some operate in one location; others run multiple sites. Availability varies widely — some book weeks out, others have same-week slots.

Before you contact an examiner, you need a Commercial Learner's Permit (CLP) from the Secretary of State. You get the CLP by passing the written knowledge test at a Secretary of State facility or through their online testing system. Only after you hold the CLP can you schedule a skills test with a third-party examiner.

Key Takeaways

  • Illinois CDL skills tests are administered by private examiners, not state offices, so you must contact them directly to schedule.
  • You must obtain a Commercial Learner's Permit from the Secretary of State before you can test with any examiner.
  • The Secretary of State publishes the full list of approved examiners by county on its website, including their contact information and locations.
  • Examiner fees, hours, and availability differ by location, so calling ahead to confirm scheduling is necessary.
  • Some examiners offer both the written CLP test and the skills test; others only offer skills testing.

How to Find an Approved Examiner Near You

Start by visiting the Illinois Secretary of State website and searching for "CDL examiners" or "third-party examiners." The state publishes a searchable list organized by county. Each examiner entry includes their business name, phone number, address, and sometimes their website.

Call the examiner directly to confirm they are currently accepting new test candidates. Some examiners specialize in certain CDL classes (Class A, B, or C) or endorsements (hazmat, tanker, passenger). Ask whether they offer both the CLP written test and the skills test, or only one. Many examiners only administer skills tests and refer you elsewhere for the written exam.

When you call, ask about their current wait time, their fee structure, what documents you need to bring, and whether they require a pre-test vehicle inspection. Some examiners use your own truck; others provide one. Policies vary significantly.

Secretary of State Locations for Your Commercial Learner's Permit

You obtain your Commercial Learner's Permit by passing the written knowledge test. Illinois Secretary of State has multiple office locations statewide where you can test in person. The main Chicago office is at 505 West Madison Street, Chicago, IL 60661. Regional offices exist in Springfield, Champaign, Rockford, and other major cities.

You can also take the written test online through the Secretary of State's remote testing system if you meet their requirements. Remote testing is available during specified hours and requires a valid ID and a quiet, private space. Check the Secretary of State website for current remote testing availability and scheduling.

Bring your valid driver's license, proof of residency, and Social Security number or ITIN. The written test covers traffic laws, vehicle operation, and safety rules specific to commercial driving. You must score at least 80 percent to pass. The test takes about 30 to 45 minutes.

What to Expect When You Schedule a Skills Test

Once you hold your CLP, contact your chosen examiner to schedule the skills test. The skills test has three parts: the pre-trip vehicle inspection, the basic control skills test, and the road test. The entire process typically takes two to three hours.

Bring your CLP, valid driver's license, and proof of insurance for the vehicle you will use. Some examiners require you to bring your own truck; others provide one. Confirm this when you schedule. You will also need to pass a Department of Transportation (DOT) medical examination before testing — your examiner can refer you to an approved medical examiner or you can find one through the FMCSA website.

The examiner will evaluate your ability to perform a pre-trip inspection, maneuver the vehicle in a controlled space, and drive safely on public roads. You must demonstrate proper mirror checks, lane changes, backing, and hazard awareness. Failure in any section means you do not pass; you can retake the test, but you must schedule and pay again.

Major Illinois Cities and Examiner Availability

Chicago and the surrounding Cook County area has the highest concentration of approved examiners. Multiple private testing companies operate sites in Chicago, Evanston, and suburbs. Availability in the Chicago area is typically better than downstate, but demand is also higher — expect longer wait times during peak seasons (spring and summer).

Downstate cities like Springfield, Champaign, Peoria, and Rockford have fewer examiners, which can mean longer waits or travel distances. Rural counties may have only one or two examiners serving the entire area. If your county has no examiner, you may need to travel to an adjacent county.

The Secretary of State website lists examiners by county, so you can see exactly which ones serve your area and which neighboring counties might be closer. Some examiners are willing to travel or test at truck stops or training facilities, so ask when you call.

Costs and What Affects Your Total Expense

The Secretary of State charges a fee for the CLP written test — this varies depending on whether you test in person or online, but is typically under $50. The skills test fee is set by each individual examiner and ranges from roughly $100 to $300, depending on the examiner, the CDL class, and whether they provide a vehicle.

You will also need a DOT medical examination, which costs between $75 and $150 and is not covered by the state. Some examiners have relationships with specific medical examiners and can schedule this for you; others require you to arrange it independently.

If you use your own vehicle for the skills test, you are responsible for fuel and wear. If the examiner provides a vehicle, that cost is usually included in their testing fee. Ask for a complete fee breakdown before you schedule.

Frequently Asked Questions

Can I test at a Secretary of State office for my CDL skills test?

No. The Secretary of State only administers the written Commercial Learner's Permit test. All CDL skills tests are conducted by private third-party examiners. You must contact an approved examiner directly to schedule.

Do I need a Commercial Learner's Permit before I can take the skills test?

Yes. You must pass the written knowledge test and hold a valid CLP before any examiner will let you take the skills test. The CLP proves you understand the rules of the road for commercial driving.

What if there is no examiner in my county?

Check the Secretary of State's examiner list for neighboring counties. Many examiners serve multiple counties or are willing to test at locations outside their home county. You can also contact the Secretary of State directly for guidance on the nearest available examiner.

How long does it take to get an appointment with an examiner?

Wait times vary by location and season. Chicago-area examiners may have waits of several weeks during busy months. Downstate examiners may have shorter waits but fewer total slots. Call early and ask about current availability when you contact them.

Can I use my own truck for the skills test?

Most examiners allow it, but policies differ. Some require you to use a truck they provide. Ask when you schedule. If you use your own vehicle, it must pass a pre-trip inspection and meet DOT safety standards.
