Excessive speeding involving any single offense for any speed of 15 mph or more above the posted speed limit.

The following may also result in excessive speeding:

  • Failure to reduce speed to avoid an accident.
  • Driving too fast for conditions.
  • Exceeding the speed limit in a school zone.

TruckingTruth's Advice:

Excessive speeding is considered a "serious traffic violation." Two serious traffic violations within a three-year period results in a two-month disqualification. Three serious traffic violations in the same period results in a four-month disqualification.

Drivers attempting to obtain a Class-A CDL must also take which of the following exams:
  • Driving Exam
  • Basic Control Skills 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.

Following too closely is considered a serious traffic violation. Which of these is considered following too closely?
  • Failure of a truck to leave sufficient distance for being overtaken by another vehicle
  • Less than 12 seconds of following distance
  • Less than 8 seconds of following distance
  • Less than 400ft of following distance
This is a question from page 3 - click here to look up the answer

Quote From Page 9 Of The Illinois CDL Manual:

Following Too Closely:

  • Following the vehicle ahead too closely.
  • Failure of a truck to leave sufficient distance for being overtaken by another vehicle.

TruckingTruth's Advice:

While the CDL manual specifically states "failure of a truck to leave sufficient distance for being overtaken by another vehicle" there are many scenarios in which a driver can be charged with following too closely. But that is the answer you'll most likely see if asked on an exam.

Following too closely is considered a serious traffic violation and carries with it additional consequences. Two serious traffic violations within a three-year period results in a two-month disqualification. Three serious traffic violations in the same period results in a four-month disqualification.

Following too closely is one of the most dangerous things you can do. Keeping plenty of following distance is absolutely critical to safe driving.

How many CDL endorsements are there?
  • 9
  • 4
  • 7
  • 5
This is a question from page 2 - click here to look up the answer

Quote From Page 4 Of The Illinois CDL Manual:

There are seven special CDL endorsements and one restriction that require testing. In addition, drivers who do not pass the air brake portion of the exams are restricted to driving vehicles without air brakes.

TruckingTruth's Advice:

We highly recommend that everyone get all endorsements available because:

  • You don't want to restrict your opportunities
  • The tests are fairly quick, simple, and inexpensive
  • You're already going through the process of learning the materials anyhow

So make sure you get all of the endorsements.

If you are caught violating a DOT out of service order, you will receive a driving disqualification for:
  • A minimum of 1 year
  • A minimum of 9 months
  • A minimum of 6 months
  • A minimum of 3 months
This is a question from page 3 - click here to look up the answer

Quote From Page 8 Of The Illinois CDL Manual:

A conviction for violation of an out-of-service order results in disqualification for a minimum six months

TruckingTruth's Advice:

The department of transportation may put drivers out-of-service for several reasons, including equipment problems, hours of service violations, alcohol violations, and any other reason they deem fit. Do not violate the out-of-service order as that is a very serious offense and could ruin your career.

  • A farmer driving a combination vehicle equipped with air brakes
  • A recreational vehicle longer than 35 feet in length
  • Driving a vehicle weighing more than 26,001 for commercial purposes across state lines
This is a question from page 1 - click here to look up the answer

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.
