The operator of a commercial motor vehicle can be criminally charged with driving under the influence of alcohol with a BAC of:
  • .08
  • .02
  • .05
  • .04
This is a question from page 3 - click here to look up the answer

Quote From Page 8 Of The Illinois CDL Manual:

A CDL holder may not operate a commercial vehicle with a BAC of .04 or more or a noncommercial vehicle with a BAC of .08 or more.

TruckingTruth's Advice:

It is important to note that any CDL holder found operating a commercial vehicle with any level of alcohol in his or her system will be placed out of service for a minimum of 24hrs. Drivers will not be criminally charged unless their BAC is .04 or higher, but commercial drivers are not allowed to operate commercial vehicles with even a trace amount of alcohol in their system.

And don't even think about having any alcohol anywhere in the cab of the truck at anytime - not even in the side box. If you get caught with it, it will likely be the end of your job, and possibly worse.

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.

Special lighting for commercial vehicles are required between what times?
  • One hour before sunset to one hour after sunrise
  • Special lighting is recommended, but not legally required
  • Sunset to sunrise
  • Special lighting must always be present on commercial vehicles
This is a question from page 5 - click here to look up the answer

Quote From Page 10 Of The Illinois CDL Manual:

Lighting equipment is required on vehicles operated outside the limits of cities, towns or villages between sunset and sunrise.

TruckingTruth's Advice:

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.

  • Any amount
  • BAC of .04

  • BAC of .02
This is a question from page 3 - click here to look up the answer

A CDL holder may not operate a commercial vehicle with a BAC of .04 or more or a noncommercial vehicle with a BAC of .08 or more.

  • Any driver operating a CMV or non-CMV who refuses to submit to chemical testing or submits to a test with results in excess of the legal limit is disqualified for a minimum 12 months.
  • Any driver convicted of DUI (regardless of BAC) is disqualified for a minimum 12 months.
  • If either violation above takes place while transporting placarded hazardous materials, the driver is disqualified for a minimum three years.
  • A driver who commits two of the above violations, arising from two or more incidents, is disqualified for life.

  • Anyone convicted of driving a commercial motor vehicle with any amount of drug, substance or compound resulting from unlawful use or consumption of cannabis listed in the Cannabis Control Act or controlled substance listed in the Controlled Substance Act is disqualified for a minimum 12 months.

TruckingTruth's Advice:

CDL holders can be criminally charged for driving under the influence with a .04 BAC or higher, but will be placed out of service for 24 hours if any trace of alcohol is detected in their system
