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

Quote From Page 3 Of The Illinois CDL Manual:

The following vehicle operators are not required to obtain a CDL:

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
  • Not used in the operations of a common or contract carrier; and
  • Used in nursery or agricultural operations.

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.

  • Firefighting Equipment Operators - Because most firefighting organizations have extensive initial training and retraining requirements for their equipment operators, Illinois waives CDL requirements for operators of firefighting equipment owned or operated by or for a government agency, when responding to or returning from an emergency.
  • Military Vehicle Operators - Operators of military vehicles for military purposes are exempt from obtaining a CDL.
  • Recreational Vehicle Operators - Recreational vehicle operators, when using the vehicle primarily for personal use, do not need a CDL.

A CDL must be obtained by the driver of any of the following vehicles:

  • Any combination of vehicles with a gross combination weight rating (GCWR) of 26,001 or more pounds, providing the gross vehicle weight rating (GVWR) of the vehicle being towed is in excess of 10,000 pounds.
  • Any single vehicle with a GVWR of 26,001 or more pounds, or any such vehicle towing another not in excess of 10,000 pounds.
  • Any vehicle, regardless of size, designed to transport 16 or more persons, including the driver.
  • Any vehicle required by federal regulations to be placarded while transporting hazardous materials.
