Quote From Page 5 Of The Illinois CDL Manual:

Computerized Written Knowledge Exam - The computerized written knowledge exam consists of standardized multiple-choice questions. In addition, specialized exams are added if you wish to operate any of the following vehicles:

  • Vehicles with air brakes (also requires a skills and road test)
  • Combination vehicles
  • Double or triple trailers
  • Vehicles carrying hazardous materials
  • Passenger-carrying vehicles
  • School buses
  • Tanker vehicles

TruckingTruth's Advice:

For truck drivers, it's most important to be able to pass the General Knowledge, Air Brakes, and Combination Vehicles exams first. Once you are able to pass those exams, it's highly recommended you also take the Tanker, Double/Triple Trailers, Passenger, and Hazardous Materials exams.

Quote From Page 8 Of The Illinois CDL Manual:

Law requires drivers operating a commercial motor vehicle (CMV) or a non-commercial motor vehicle (nonCMV) on highways to automatically give their consent to submit to certain tests to determine blood-alcohol concentration (BAC). A CDL holder may not operate a commercial vehicle with a BAC of .04 or more or a noncommercial vehicle with a BAC of .08 or more.

  • Any driver operating a CMV or non-CMV who refuses to submit to chemical testing or submits to a test with results in excess of the legal limit is disqualified for a minimum 12 months.
  • Any driver convicted of DUI (regardless of BAC) is disqualified for a minimum 12 months.
  • If either violation above takes place while transporting placarded hazardous materials, the driver is disqualified for a minimum three years.
  • A driver who commits two of the above violations, arising from two or more incidents, is disqualified for life.
  • A CDL holder operating a CMV found to have any alcohol in his or her system is placed out of service for at least 24 hours.
  • Anyone convicted of driving a commercial motor vehicle with any amount of drug, substance or compound resulting from unlawful use or consumption of cannabis listed in the Cannabis Control Act or controlled substance listed in the Controlled Substance Act is disqualified for a minimum 12 months.

TruckingTruth's Advice:

Please note the limit to be criminally charged for DUI when operating a commercial vehicle is a BAC of .04. However, anyone caught operating a commercial vehicle with any amount of alcohol will be placed out of service for a minimum of 24hrs. Most trucking companies will immediately discharge a driver caught with any amount of alcohol in their system.

  • Driving a vehicle weighing more than 26,001 for commercial purposes across state lines
  • A recreational vehicle longer than 35 feet in length

Quote From Page 3 Of The Illinois CDL Manual:

The following vehicle operators are not required to obtain a CDL:

Farm Equipment Operators - This exemption covers legitimate farm-to-market operations by farmers, not commercial grain haulers. CDLs are not required to operate vehicles:

  • Controlled and operated by a farmer, a member of the farmer's family or an employee;
  • Used to transport farm products, equipment or supplies to or from a farm (including nurseries and aquacultures);
  • Used within 150 air miles of the farm; and
  • Not used in the operations of a common or contract carrier; and
  • Used in nursery or agricultural operations.

NOTE: For the drivers of truck-tractor semitrailers, the farmer, his or her spouse and their children, parents on both sides, brothers and sisters on both sides and their spouses operating a truck-tractor semitrailer and meeting the above criteria also are exempted from the CDL Program. These drivers must be at least age 21, and the vehicle must have Farm plates. These drivers are still required to take the appropriate CDL written, skills and road tests to be licensed.

  • Firefighting Equipment Operators - Because most firefighting organizations have extensive initial training and retraining requirements for their equipment operators, Illinois waives CDL requirements for operators of firefighting equipment owned or operated by or for a government agency, when responding to or returning from an emergency.
  • Military Vehicle Operators - Operators of military vehicles for military purposes are exempt from obtaining a CDL.
  • Recreational Vehicle Operators - Recreational vehicle operators, when using the vehicle primarily for personal use, do not need a CDL.

A CDL must be obtained by the driver of any of the following vehicles:

  • Any combination of vehicles with a gross combination weight rating (GCWR) of 26,001 or more pounds, providing the gross vehicle weight rating (GVWR) of the vehicle being towed is in excess of 10,000 pounds.
  • Any single vehicle with a GVWR of 26,001 or more pounds, or any such vehicle towing another not in excess of 10,000 pounds.
  • Any vehicle, regardless of size, designed to transport 16 or more persons, including the driver.
  • Any vehicle required by federal regulations to be placarded while transporting hazardous materials.

What is the maximum weight limit for a 5-axle combination vehicle?
  • 100,000 pounds
  • 20,000 pounds
  • 80,000 pounds
  • 34,000 pounds
This is a question from page 4 - click here to look up the answer

Quote From Page 10 Of The Illinois CDL Manual:

Weight

The maximum weight limits on both designated and non-designated streets and highways are:

  • 20,000 pounds on a single axle.
  • 34,000 pounds on a tandem, and
  • Up to 80,000 pounds of total weight on a 5-axle combination, depending upon axle spacing.
  • 20,000 pounds on a single axle
  • 34,000 pounds on a tandem
  • 80,000 pounds on a 5-axle combination, depending upon axle spacings.

TruckingTruth's Advice:

A "tandem" is a reference for a pair of axles. For example, the rear 2 axles on a tractor and the rear two axles on the trailer are considered tandems. So a single axle (such as the front axle) can have a maximum of 20,000 pounds. A tandem (two axles in close proximity) may have 34,000 pounds. But the entire weight of the vehicle can not exceed 80,000 pounds.

Drivers attempting to obtain a Class-A CDL must also take which of the following exams:
  • Basic Control Skills Exam
  • Driving Exam
  • Pre-Trip Inspection Exam
  • All of these exams must be taken
This is a question from page 2 - click here to look up the answer

Quote From Page 5 Of The Illinois CDL Manual:

After passing the written exam, some drivers are required to pass a skills and driving exam. The exam is divided into three parts:

  • 1) The pre-trip inspection is conducted to determine whether the applicant knows how to inspect the vehicle to see if it is safe to drive. Drivers are asked to conduct a pre-trip inspection. The driver must explain to the examiner what is being inspected and why.
  • 2) The basic control skills exam evaluates a driverʼs ability to use basic skills to control the vehicle. Applicants complete exercises on a course marked by lines, traffic cones or similar boundaries. The exercises test the driverʼs ability to move the vehicle forward, backward and through turning movements. Drivers are scored on how well they stay within the boundaries.
  • 3) The driving exam tests the driverʼs ability to drive safely in a variety of on-road situations. The road test route may include left and right turns, intersections, railway crossings, curves, upgrades, downgrades, rural or semi-rural routes, multi-lane city streets and/or expressway driving.

TruckingTruth's Advice:

To obtain a CDL driving permit, all written exams must be passed. At that point, permit holders are able to drive commercial vehicles with the aid of a licensed CDL instructor who will help coach the student to pass the pre-trip, basic control, and driving exams at a later date.
