Age and residency

You must be at least 18 years old to apply for an Illinois CDL for interstate driving. For interstate driving, you must be at least 21 years old. You also need to be a resident of the United States and have a valid Illinois driver’s license.

How to get a CDL license in Illinois?

Step 1: Meet the requirements

The first step in obtaining a CDL in Illinois is making sure you meet the minimum eligibility criteria. At the very least, you must satisfy the following conditions:

  • Be at least 18 years old to operate a commercial vehicle within the state, or 21 years old to drive across state lines (interstate) or transport hazardous materials.
  • Hold a valid Illinois driver’s license.
  • Provide proof of U.S. citizenship or lawful permanent residency, as well as documentation verifying your residency in Illinois.

Step 2: Determine your CDL Class

Another crucial step you cannot overlook is deciding which CDL class you need. This choice determines the type of training program you’ll enroll in, helping you avoid wasting time or money on the wrong course. Each CDL class comes with its own requirements, training length, and driving privileges.

In Illinois, there are three main CDL classes:

  • Class A: Required for operating any combination of vehicles with a Gross Combination Weight Rating (GCWR) of 26,001 pounds or more, provided the vehicle being towed weighs more than 10,000 pounds.
  • Class B: Applies to a single vehicle with a GCWR of 26,001 pounds or more, towing a vehicle weighing less than 10,000 pounds. This category typically includes straight trucks, dump trucks, and large buses.
  • Class C: Covers smaller vehicles that either transport hazardous materials (requiring placards) or are designed to carry 16 or more passengers, including the driver.

In addition to your CDL class, certain types of commercial driving may require special endorsements on your license, such as:

  • N – Tank vehicles
  • H – Hazardous materials
  • P – Passenger transport
  • T – Double/Triple trailers

Step 3: Obtain a Commercial Learner’s Permit (CLP)

The next step toward earning your Illinois CDL is applying for a Commercial Learner’s Permit (CLP). This permit allows you to practice operating a commercial vehicle under the supervision of a licensed CDL holder, giving you hands-on experience before the road test.

To qualify for a CLP, you must meet the following requirements:

  • Knowledge Test: You must pass a written knowledge exam based on the Illinois CDL Manual. The test covers essential topics such as general knowledge of commercial driving, air brakes, and combination vehicles. You can practice the Illinois practice tests for free at Easy Prep.
  • Documentation: Bring valid identification, proof of residency in Illinois, and your Social Security card. These documents verify your eligibility and legal presence.
  • Medical Certification: You are required to present a valid Medical Examiner’s Certificate (Form MCSA-5876). This certificate must be issued by a qualified medical examiner listed in the National Registry of Certified Medical Examiners (NRCME), following a physical examination that meets FMCSA standards.

Once you successfully pass the written exam and submit all required documents, you will be issued a CLP. The permit is valid for 180 days, giving you ample time to practice driving a commercial vehicle under supervision before scheduling your CDL skills test.

Step 4: Attend CDL Training

Once you have your CLP and know which CDL class you need, the next step is enrolling in a CDL training program. In Illinois, you have several options for CDL training:

  • Private truck driving schools: These schools specialize in CDL instruction and often provide flexible schedules, intensive courses, and hands-on driving practice with commercial vehicles.
  • Community colleges: Many community colleges in Illinois offer affordable CDL programs that combine classroom instruction with supervised driving practice. These programs may also provide additional career services, such as job placement support.
  • Employer-sponsored training programs: Some trucking companies offer paid or tuition-free CDL training in exchange for a work commitment after graduation. This can be a cost-effective way to start your career while securing a job immediately after earning your CDL.

Step 5: Complete ELDT Training

Illinois requires all CDL applicants to complete an approved Entry-Level Driver Training (ELDT) program, which includes both theory instruction (classroom) and behind-the-wheel driving practice.

This training is mandatory for:

  • First-time CDL applicants.
  • Drivers who wish to upgrade their current CDL to a higher class.
  • Drivers adding specific endorsements, such as Hazardous Materials (HazMat).

Step 6: Schedule and take the skills/driving test

After completing your training, the next step is to take the Illinois CDL skills test. You must hold your Commercial Learner’s Permit (CLP) for at least 14 days before you are eligible to schedule the exam at an authorized testing location.

The CDL skills test is divided into three parts:

  • Pre-Trip Inspection: You will be asked to identify and explain key vehicle parts and systems to demonstrate your knowledge of safety and maintenance checks.
  • Basic Vehicle Control: You must perform essential maneuvers such as backing, parallel parking, and offset backing to show that you can handle the vehicle in tight spaces.
  • Road Test: Finally, you will drive on public roads, where the examiner will evaluate your ability to operate the vehicle safely in real traffic conditions.

Step 7: Pay fees

After successfully passing the skills test, the final step before receiving your license is to pay the required CDL fees. In Illinois, the cost depends on the CDL class you are applying for:

  • Class A: $60
  • Class B: $50
  • Class C: $50

Once the payment is made, your CDL will be officially processed and issued.

Step 8: Obtain your CDL
