Number of Question
1. A person working on a disabled vehicle on the shoulder of a road:

2. During a trip, which 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.
3. When coupling a trailer:
When coupling, make sure you couple matching glad hands. They are often color-coded to help drivers avoid mistakes. Typically, blue is used for service lines and red is used for emergency lines.

You must have a CDL with a hazardous materials endorsement to drive a vehicle of any size that is used to transport hazardous materials.
