19 / 30

Some older vehicles are equipped with a low-air warning device near the top of the windshield that drops into the driver's view when air pressure drops. What is this?

A wig wag

A mig mag

A woggle

A toggle

20 / 30

When air pressure is high enough in the system, what does the governor do?

It reduces the flow of air being pumped in

It causes the compressor to stop pumping air

None of the above

It sends a warning light to the dashboard

21 / 30

What can the collected moisture and oil mixture from the supply tank form?

Water

Sludge

A solid
