Illinois CDL General Knowledge: Shifting Gears Test 2026

Shifting a loaded truck smoothly is a learned rhythm, and the Illinois CDL shifting gears test checks that you understand the mechanics behind it. This Illinois CDL shifting practice test for 2026 covers double clutching, using engine speed and road speed to pick the right gear, upshifting on the tachometer rather than by ear alone, downshifting before a curve or a grade instead of during it, and why coasting out of gear is both unsafe and illegal.

Multi-speed transmissions, splitter and range controls, and automatic transmissions all appear. So does the point that grinding gears on an incline usually means the shift came too late.

Shifting questions belong to the Illinois CDL general knowledge test, which the Illinois Secretary of State gives as a 50-question written exam with an 80 percent passing score. Study this drill next to the shifting chapter of the Illinois CDL Manual and repeat the CDL shifting questions until the sequence is automatic.
