B. 16,001 pounds or more but less than 26,001 pounds
C. 10,001 pounds or less
D. Any vehicle over 10,000 pounds regardless of use
Correct Answer: C
Rationale: Illinois classifies a Class B Non-CDL vehicle as a single vehicle with a GVWR of 16,001
pounds or more, but less than 26,001 pounds, or a combination of vehicles with a GCWR in that range
when the towed vehicle is 10,000 pounds or less. This aligns with the Illinois Vehicle Code and SOS

C. No mirrors if the vehicle has a backup camera
D. A fire extinguisher only if transporting hazardous materials
Correct Answer: A
Rationale: Illinois Rules of the Road require adequate mirrors for visibility to the rear, operational
lighting systems, and a functional horn. Proper equipment is essential for safe operation of larger
vehicles.

on Illinois roadways?
A. Only the fuel level
B. Brakes, tires, lights, mirrors, windshield, and coupling devices if towing

vehicles, without a special permit is:
A. 8 feet 6 inches
B. 10 feet
C. 12 feet

is:
A. Optional if the hitch is rated high enough
