Drivers Exempt From Obtaining a CDL
Under state and federal law, certain drivers are not subject to the requirements of the CDL program. The Federal Motor Carrier Safety Administration has determined these exemptions will not diminish the safe operation of commercial vehicles on the highways. Although the following vehicle operators are not required to obtain CDLs, they are required to hold the proper driver's license classification for the type of vehicles they are operating.
- Farm Equipment Operators — The farm operators' exemption is intended to cover legitimate farm-to-market operations by farmers, not commercial grain haulers. If the farmer, his spouse and their children, parents on both sides, brothers and sisters on both sides and their spouses are operating a truck-tractor semi-trailer combination or combinations and meet the below criteria, they are also exempt from the CDL Program. However, these drivers must be age 21 and the vehicle must have Farm plates. CDLs are not required to operate vehicles that are:
- Controlled and operated by a farmer, a member of the farmer's family or an employee;
- Used to transport farm products, equipment, supplies or a combination thereof to or from a farm (including nurseries and aquacultures);
- Used within 150 air miles of the person's farm;
- Not used in the operations of a common or contract motor carrier; and
- Used in nursery or agricultural operations.
- Emergency Equipment Operators — Because emergency organizations have extensive initial training and re-training requirements for their equipment operators, Illinois waives CDL requirements for operators of emergency equipment operated for a government agency. The emergency equipment must have audible and visual signals. The exemption applies when the equipment is being used in the execution of functions for the preservation of life or property.
- Recreational Vehicle Operators — Illinois waives CDL requirements for drivers of a recreational vehicle operated as family/personal conveyance for recreational purposes. This includes motor homes, travel trailers and other recreational vehicles.
- Military Vehicle Operators — U.S. Department of Defense military vehicles being driven by non-civilian personnel for military purposes are exempt from CDL requirements. This includes any driver on active military duty, members of the Reserves, National Guard, personnel on part-time training and National Guard military technicians.
- Township Employees — An employee of a township or road district with a population of less than 3,000, driving a vehicle within the boundaries of the township or road district for the purpose of removing snow or ice from a roadway by plowing, sanding or salting, is waived from CDL requirements. This exemption is allowed providing that the employee who ordinarily operates the vehicle and holds a properly classified CDL is unable to operate the vehicle or is in need of additional assistance due to a snow emergency.
A holder of a Non-CDL class A and B license is permitted to operate vehicles for the above purposes and other non-commercial vehicles at their class level or below.
A holder of a Non-CDL class A for farming purposes cannot operate a semi-tractor and trailer without the J-50 restriction.

Persons who drive commercial motor vehicles (CMV) are subject to minimum physical qualifications. Unless excepted (exempted) by Federal or State law, these physical qualifications require a medical examination. This physical examination is required to help ensure that a person is medically qualified to safely operate a CMV. In the interest of public safety, CMV drivers are held to higher physical, mental and emotional standards than passenger car drivers.
In general, drivers of commercial motor vehicles that have a gross vehicle weight rating (GVWR) in excess of 10,001 pounds and who are driving in commerce within the United States, Canada and Mexico must obtain medical certification from a Medical Examiner. Currently, a Medical Examiner is a person who is licensed, certified and/or registered in accordance with applicable State laws and regulations to perform physical examinations. The term includes but is not limited to doctors of medicine, doctors of osteopathy, physician assistants, advanced practice nurses and doctors of chiropractic.
Any CMV driver must pass a medical examination conducted by a licensed medical examiner. A copy of the medical examination report can be obtained through the following link — http://www.fmcsa.dot.gov/documents/safetyprograms/Medical-Report.pdf.
A CMV driver must be issued a Medical Examiner’s Certificate, which must be carried at all times and must be renewed every two years unless the medical examiner specifies a date of less than two years on the certificate. A copy of the required medical examination certificate can be obtained from the medical provider performing the medical examination, or through the following link — http://www.fmcsa.dot.gov/documents/safetyprograms/Medical-Examiners-Certificate.pdf
Beginning May 21, 2014, all interstate CMV drivers seeking a medical certificate must use a Medical Examiner on the National Registry of Certified Medical Examiners (NRCME). Medical certificates issued prior to this date are valid until the expiration date listed on the medical examination certificate. More information for CMV drivers concerning the NRCME can be obtained through the following link — https://nationalregistry.fmcsa.dot.gov/NRPublicUI/Drivers.seam
All CDL holders must self-certify their medical status in order to renew or upgrade a CDL. All CLP applicants must self-certify along with conducting their initial knowledge testing. All initial medical self-certifications must be provided at a CDL facility.
All Non-excepted interstate (NI) CDL holders must provide a current and acceptable medical examiner's certificate, performed by a National Registry Medical Examiner, during this initial self-certification process. These CDL holders must continue to keep the medical certificate valid or change their medical category to one other than NI. These updates can be accomplished by providing the updated medical certificate in-person at a CDL facility, by mailing the certificate to: Illinois Secretary of State c/o CDL Medical Unit 2701 S. Dirksen Parkway Springfield, IL 62723 or by emailing a copy of the certificate to: email@example.com.
Further information in reference to the medical program may be obtained by: visiting http://www.fmcsa.dot.gov/regulations/medical, contacting IDOT at 217-785-1181 or the Secretary of State's CDL Medical Unit at 217-782-3002.
Knowledge/Written Tests — CDL knowledge/written tests are conducted utilizing a computerized system of random questions. These tests are administered in English only. The test(s) can be read by the applicant or the audio format (computer reads test) nay be requested. After attempting the testing utilizing the audio format, if the applicant desires to have the test read in person by SOS personnel, the applicant will need to request the appropriate information information from facility management to apply for an oral test.
The computerized General (Core) Knowledge written test is a general CDL test required of all applicants to obtain a CLP or transfer a CDL. This test consists of 30 standardized, random multiple-choice questions that cover a wide range of areas concerning the CDL laws, the CDL program and CDL vehicles.
In addition to the General Knowledge test, there are Classification (combination), Air Brake and Specialized Endorsement Knowledge test depending on the type/size of vehicle and its equipment and purposes.
Endorsement Knowledge/written tests include: double/triple trailers, vehicles carrying hazardous materials, passenger vehicles (16+ people), school and charter buses or tank vehicles. Applicants must score a minimum of 80% to pass each applicable test, with the exception of the School Bus test which is 90%.
Skills and Drive Testing — After passing the applicable knowledge/written testing, all CLP holders or transferring CDL holders are required to pass the skills/drive testing. All CLP holders, whether initial, renewal or upgrading existing CDL, will be required to hold their CLP for a minimum of 14 calendar days from the CLP issue date, prior to conducting their skills/drive testing.
Drive/Road Tests — All CDL applicants must drive an approved predetermined route for a CDL Road Test. The CDL Road Test route is determined by the requirements of federal and state law along with the roadways in the surrounding area of the CDL facility in which the test is being conducted.
Each portion of the skills/drive test must be taken in a vehicle representative of the license classification and type of vehicle you wish to drive, with the proper air brake system if so desired. You must schedule CDL skills/drive testing at Schedule a CDL Appointment or by calling 217-785-3013, option #4.
