West Virginia CDL General Knowledge: Mountain Driving Test 2026

West Virginia's Appalachian grades make mountain driving one of the most practical sections on the state's CDL general knowledge test, and this practice quiz treats it that way. Long downgrades on I-77 and I-79 punish drivers who do not know how to manage speed and gearing before the grade starts, and the questions here walk through exactly that.

You will see prompts on selecting the right gear before a descent, using engine braking instead of riding the service brakes, recognizing runaway-truck ramps, and adjusting following distance on steep, winding roads. The West Virginia CDL Manual devotes real attention to mountain driving because the terrain here is not theoretical, and the 2026 CDL exam reflects that local reality.

Work through the questions, then reread the manual section on downgrade control if anything felt shaky. Mountain driving knowledge is one of the few CDL topics with an obvious real-world payoff for a West Virginia driver, so treat this practice test as more than a box to check.
