The air tanks on a trailer are filled through the:

The shut-off valves (cut-out cocks) at the rear of a trailer should be:
Answer: A. Closed on the last trailer and open between trailers in a combinationShut-off valves sit in the service and supply lines at the back of trailers used to tow other trailers, so the lines can be closed when no trailer follows. Check that every shut-off valve is open except the ones at the back of the last trailer, which must be closed. Air must reach all the way to the back for all the brakes to work.

On a trailer built before 1975 that has no spring brakes, the emergency brakes work from:
Answer: C. Air stored in the trailer air tank, so the brakes let go once that air leaks awayWithout spring brakes, the trailer's emergency brakes work only as long as there is air pressure in the trailer tank. If the air leaks away, there are no brakes at all.

When you park a trailer that has no spring brakes, you should:

How the West Virginia CDL knowledge test works
You take the general knowledge test first; it is required for every CDL class. Class A drivers add the combination vehicles test. Almost everyone takes the air brakes test, because skipping it puts an air brake restriction on the licence. Endorsements (hazmat, tanker, doubles/triples, passenger, school bus) each have their own knowledge test. Pass the tests and you hold a commercial learner's permit; the skills test in a truck comes later.
Fees, appointment rules and test centre locations are set by West Virginia; the current ones from WV DMV are in the next section. What does not change is the content, and that is what PassRig drills.
