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.

  • Gross Vehicle Weight Rating
  • Grain Vehicle With Restrictions
  • Gross Vehicle Width Rating
  • General Vehicle Without Restrictions
This is a question from page 1 - click here to look up the answer

Quote From Page 3 Of The Illinois CDL Manual:

GVWR (Gross Vehicle Weight Rating) - Value specified by the manufacturer as the maximum loaded weight of a single vehicle or combination of vehicles, or the registered gross weight.

TruckingTruth's Advice:

Be sure to have this memorized and understand how it's different from GCWR (Gross Combination Weight Rating). You'll most likely see a question related to CVWR / GCWR definitions on the written exam.

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 400ft of following distance
  • Less than 8 seconds of following distance
  • Less than 12 seconds 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.
