Illinois CDL General Knowledge: Distracted Test 2026

Three of the biggest crash causes on Illinois interstates have nothing to do with mechanical failure, and the Illinois CDL distracted, aggressive, and impaired driving test targets all three. This 2026 Illinois CDL practice test covers the federal ban on hand-held phone use and texting behind the wheel, eating and reaching that pull your eyes off the road, the fatigue that builds on long I-80 runs, and how alcohol and both prescription and over-the-counter medication degrade judgment long before a driver feels affected.

Aggressive driving gets its own attention: tailgating, speed as intimidation, weaving between lanes, and how to give a road-rage driver room instead of a target. Commercial drivers carry a stricter alcohol standard than car drivers, and the Illinois CDL Manual states it plainly.

For reference, the Illinois CDL general knowledge exam runs 50 questions with a 40-correct, 80 percent passing score. Repeat this Illinois CDL impaired driving practice test until the rules are reflexes.
