Reckless Driving Operating a CMV or non-CMV in a manner that exhibits a willful, wanton or reckless disregard of the safety of persons or property.

  • Passing a vehicle stopped for a pedestrian in a crosswalk.
  • Driving on a sidewalk.
  • Passing a school bus receiving or discharging passengers or displaying a warning not to pass.

TruckingTruth's Advice:

Reckless driving is a serious traffic violation which carries 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.

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

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.

  • You're already going through the process of learning the materials anyhow

So make sure you get all of the endorsements.
