A Message From Brett Aquila Of TruckingTruth

CDL practice tests are a great way to reinforce the knowledge you already have of the materials in the CDL Manual. But what's the best way to learn the CDL manual in the first place? Read more

We have an incredibly easy to use (and free!) online program:

The High Road™ Training Program

It has the entire CDL Manual built right in and it's broken down into small chunks with multiple choice questions after each section. Our program will teach you the CDL manual cover to cover and prepare you for your written CDL exams, including your permit and all of your endorsements.
The questions in this section of our website are straight out of The High Road™ Training Program. Do yourself a favor and take five minutes to check it out. You're going to be amazed at how thoroughly and easily you can learn the entire CDL manual and breeze through your written CDL exams, including all of the endorsements, with a program that's put together as well as ours.
Recently a student in our trucker's forum aced the entire CDL permit exam and all of his endorsement exams after using our training program! Here's what he had to say: Aced The CDL Exams.

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.

A Farm Equipment Operator must obtain a CDL if...

  • Farm equipment operators are always exempt from obtaining a CDL provided they are transporting farm products, equipment or supplies to or from a farm
  • The farm equipment operator will be traveling further than 150 miles from his or her farm
This is a question from page 1 - click here to look up the answer

Quote From Page 3 Of The Illinois CDL Manual:

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

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.

A commercial driver may be placed out of service with how much alcohol in his/her system?
  • BAC of .08
  • BAC of .02
  • Any amount
  • BAC of .04
This is a question from page 3 - click here to look up the answer

Quote From Page 8 Of The Illinois CDL Manual:

Illinois law requires drivers operating a commercial motor vehicle (CMV) or a non-commercial motor vehicle (nonCMV) on highways to automatically give their consent to submit to certain tests to determine blood-alcohol concentration (BAC). 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.
  • A CDL holder operating a CMV found to have any alcohol in his or her system is placed out of service for at least 24 hours.
  • 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

What is the maximum weight limit for a 5-axle combination vehicle?
  • 100,000 pounds
  • 20,000 pounds
  • 80,000 pounds
  • 34,000 pounds
This is a question from page 4 - click here to look up the answer

Quote From Page 10 Of The Illinois CDL Manual:

Weight

The maximum weight limits on both designated and non-designated streets and highways are:

  • 20,000 pounds on a single axle.
  • 34,000 pounds on a tandem, and
  • Up to 80,000 pounds of total weight on a 5-axle combination, depending upon axle spacing.
  • 20,000 pounds on a single axle
  • 34,000 pounds on a tandem
  • 80,000 pounds on a 5-axle combination, depending upon axle spacings.

TruckingTruth's Advice:

A "tandem" is a reference for a pair of axles. For example, the rear 2 axles on a tractor and the rear two axles on the trailer are considered tandems. So a single axle (such as the front axle) can have a maximum of 20,000 pounds. A tandem (two axles in close proximity) may have 34,000 pounds. But the entire weight of the vehicle can not exceed 80,000 pounds.

The operator of a commercial motor vehicle can be criminally charged with driving under the influence of alcohol with a BAC of:
  • .08
  • .04
  • .05
  • .02
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.
