1 . After finishing a pre-trip inspection, you should:
Leave the rear shut-off valves open.
Before a trip, you should ensure that air reaches all air brakes on all trailers by opening up the rear emergency line and service line shut-off valves to listen for escaping air. Close both shut-off valves before beginning to drive.
2 . When driving a vehicle equipped with an Anti-Lock Braking System (ABS), brakes should be applied:
When driving a vehicle with ABS, you should brake in the same manner as you would in a vehicle without ABS.
3 . During a trip, the ____ 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 it is not able to escape from the back of the vehicle.
4 . When coupling a trailer:
Only one set of glad hands should be connected.
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.
5 . Rollovers happen when drivers:
Drive illegally.
A rollover happens as a result of a driver taking a turn at too high a speed. Be sure to take turns and curves safely and slowly.
6 . Look into the back of the fifth wheel:
While inspecting a coupling, you should go under the trailer and look into the back of the fifth wheel. Ensure that the fifth wheel jaws are secured around the shank of the kingpin.
7 . To prevent a rollover, a driver should:
Turn quickly.
Rollovers can happen when a combination vehicle is turned too quickly. To help prevent the risk of rollover, it is important to keep the vehicle's center of gravity low by loading cargo as close to the ground as possible.
