Close the vents.

13 . Coupling can be tested by a driver:
Releasing the orange lever in the cab.
It is essential to safety that a driver inspects coupling before starting a trip. Trailer coupling on a double or triple combination can be tested by pulling against the pin of the second semi-trailer.
14 . How should you test the low pressure warning signal?
Uncouple and recouple all glad hands.
It is essential that your low pressure warning light functions properly. After allowing the system to charge, you can test the warning signal by rapidly applying and releasing the brake pedal. This will release air from the braking system and the warning signal should come on when pressure drops to a dangerous level.
