TruckingTruth's Advice:

Be sure to memorize the different CDL classes, including the various weight limits for each, as at least one question almost always comes up during the state exam.

Any burnt out lights or improperly displayed lights is one way law enforcement officers decide which trucks to inspect. So it is very important you always check your lights and have extra bulbs available in case any of them burn out.

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
  • Pre-Trip Inspection Exam
  • Basic Control Skills 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.
