What does GCWR stand for?
  • Gross Combination Width Rating
  • General Cargo Weight Rating
  • Gross Combined Weight Rating
  • General Contractor Weight Rating
This is a question from page 1 - click here to look up the answer

Quote From Page 3 Of The Illinois CDL Manual:

GCWR (Gross Combined Weight Rating) - Value specified by the manufacturer as the GVWR of the power unit plus the GVWR of the towed unit or units, or the combined registered weight of the power unit plus the towed unit(s).

TruckingTruth's Advice:

Be sure you understand the difference between GCWR and GVWR. It's best to memorize the meanings and definitions of both as it will probably show up on the written exam.

Following too closely is considered a serious traffic violation. Which of these is considered following too closely?
  • Less than 12 seconds of following distance
  • Less than 8 seconds of following distance
  • Less than 400ft of following distance
  • Failure of a truck to leave sufficient distance for being overtaken by another vehicle
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.

Drivers attempting to obtain a Class-A CDL must also take which of the following exams:
  • All of these exams must be taken
  • Driving Exam
  • Pre-Trip Inspection Exam
  • Basic Control Skills Exam
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.
