About the West Virginia CDL system parts test
Every part of an air brake system has a job, and this test makes sure you can name each one and explain what it does: the air compressor, the governor, wet and dry reservoirs, the foot valve, and the air lines connecting it all together.
West Virginia CDL applicants who can trace air from the compressor through the whole system, including where moisture gets removed and where pressure gets regulated, tend to breeze through the rest of the air brakes section. This drill builds that map piece by piece.
The true number of questions on this section comes from the West Virginia CDL Manual, updated for the current cycle. Once this drill feels easy, push on to the next one and keep stacking small wins toward your CDL.
Every question traces back to the West Virginia CDL Manual - skim the right-of-way and signs chapters before your retake.
