How to Apply for a CDL Permit in Illinois

All drivers in Illinois must first apply for the CDL permit, or CLP, before they are eligible to receive a full commercial license. The CDL permit rules allow drivers to practice operating the type CMV for which they hope to receive a license, under the supervision of a driver who already holds that license. To receive the CLP, drivers must submit the abovementioned application material in person, at one of the licensing agencies highlighted by the IDT. At the time of application, the driver will be required to pass the vision and basic knowledge exams in order to receive the permit.

A temporary CDL learners permit will be issued immediately after submitting a successful application and passing the necessary exams. A permanent license is mailed to the driver within 15 days. The driver cannot continue with state testing without the permit, which is valid for 180 days. If the CLP expires before the driver completes the commercial licensing exams, he or she will have to start the entire application process over again, from the beginning.

CDL Written Test in Illinois

All drivers must pass the CDL general knowledge test, in addition to any written tests for specific classes or endorsements, in order to receive their licenses.

Students looking for hands-on help can work with qualified instructors, after receiving their CPLs, by signing up for a commercial drivers educational program, taught by any of the providers around the state.

How to Get a CDL License in Illinois

To apply for CDL licensure, drivers must begin by meeting the application requirements mentioned previously. This includes providing proof of possessing the valid documentation, passing the knowledge exam and more. Drivers who will be driving interstate must also complete the medical questionnaire.

Once the driver has received a CLP and is preparing the CDL application, he or she should spend as much time as needed learning the ins and outs of the class of CMV he or she will be licensed to drive. The driver must have the CLP for at least two weeks before applying for a full license. At this time, the driver may have to pay additional processing fees. Once confident in his or her abilities, the driver can schedule a driving skills exam at his or her nearest commercial licensing agency to complete the final steps of the application process.
