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