  • BAC of .04
  • BAC of .02
  • BAC of .08
  • Any amount
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
