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

Farm Equipment Operators - This exemption covers legitimate farm-to-market operations by farmers, not commercial grain haulers. CDLs are not required to operate vehicles:

  • 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

  • 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.

What is the maximum weight limit for a 5-axle combination vehicle?
  • 80,000 pounds
  • 100,000 pounds
  • 20,000 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.
