2 . During a trip, which shut-off valves should be open?

No shut-off valves should be open. When starting a trip, be sure that all shut-off valves are in the open position, except for the last valves on the rear trailer. It is important that air reaches the brakes on all trailers and that the air is not able to escape from the back of the vehicle.

5 . The service air line is attached to the:

Steering wheel. The service air line carries air and is controlled by either the foot brake or trailer hand brake. The service air line is attached to relay valves, which allow the trailer brakes to be applied quickly.

6 . A combination vehicle has:

Four air lines. Combination vehicles have two air lines: a service line and an emergency line.

7 . Avoid needing to make sudden lane changes by:

Pulling off the road and waiting when there is high traffic. Making a sudden lane change can be dangerous when driving a combination vehicle. Avoid the need to make a sudden lane change by looking down the road for upcoming obstacles that will require you to change lanes.
