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

So make sure you get all of the endorsements.

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

Quote From Page 8 Of The Illinois CDL Manual:

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:

Please note the limit to be criminally charged for DUI when operating a commercial vehicle is a BAC of .04. However, anyone caught operating a commercial vehicle with any amount of alcohol will be placed out of service for a minimum of 24hrs. Most trucking companies will immediately discharge a driver caught with any amount of alcohol in their system.

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