WISCONSIN CDL AIR BRAKES PRACTICE TEST

11. Some air brake systems have an alcohol evaporator. Checking the alcohol container and filling it up as necessary:
reduces the risk of having an accident due to drowsy driving.
helps keep the engine cool, as well as lubricating it.
reduces the risk of ice in air brake valves during cold weather.
helps you avoid wheel lock up.
12. If the low air pressure warning light comes on, you should:
continue to drive normally.
call for help.
stop immediately.
set the parking brake.
13. When going down grades, you should:
shift up.
put the transmission in Neutral.
downshift to a lower gear.
rely solely on engine braking to reduce your speed.
14. To operate a vehicle equipped with air brakes, you must pass the air brakes knowledge test. Why?
If you don't pass the air brakes test, you can't get a CDL.
If you don't, you will only receive a CDL permit.
If you don't pass the air brakes test, you will be restricted to driving vehicles without air brakes.
All trucks have air brakes.
15. When meeting an oncoming vehicle at night, if the other driver does not put their low beams on, you should:
flash your high beams at the other driver.
"get back at the other driver" by putting your own high beams on.
slow down and look straight ahead in your lane.
look slightly to the right to avoid looking directly at the lights of the oncoming vehicle.
