I failed my air brake test, do you think I did?

So now you know how to pass that procedure when you re-test.

 

I'm thinking you may have misunderstood the reason for the fail. I can't image a tester would require the engine to be running during the low air warning test, and if they did, they wouldn't be doing it long as the complaints start mounting. If that's really what it was, you should take it to a supervisor because that's clearly not how the test should be performed.

 

If the key wasn’t on, the buzzer wouldn’t be heard. Makes sense She failed you, if that’s the case. If not, maybe try to wine and dine her? Sounds like She really likes You.

 

If I start the truck I fail via the dmv handbook so I actually don't.

 

Well did you pass it yesterday as this was the test day?
