8 . When lightly loaded, combination vehicles:
Should be loaded with most of the weight in the rear of the trailer.
When a combination vehicle is lightly loaded, it may have poor traction. It is very easy for wheels to lock up on lightly-loaded vehicles when they are being stopped.
9 . Fully-loaded rigs:
Should not be driven.
Because the weight of cargo gives them a higher center of gravity, fully-loaded rigs are 10 times more likely to roll over in a crash than empty rigs.
10 . If the emergency air line loses pressure:
The tractor protection valve keeps air in the trailer's braking system should the trailer break away or develop a leak. A loss of air pressure in the emergency line will cause the tractor protection valve to open and the emergency trailer brakes to activate.
11 . 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.
12 . Before a drive, ensure that air flows to all trailers by:
Rolling each trailer down a hill and testing the brakes.
Before a trip, ensure that air in the air brake system reaches all trailers. Do this by waiting for air pressure to build, then sending air to both the emergency and service lines and opening the shut-off valves on the rear of the last trailer. If air escapes from the shut-off valves in the rear of the combination, the air is being supplied to the entire vehicle.
13 . After coupling, there should be ____ between the upper and lower fifth wheel.
Three inches of space
Before a trip, be sure to inspect all couplings. There should be no space between the upper and lower fifth wheel.
14 . Using the trailer hand brake while experiencing a trailer jackknife will:
Continue the skid.
If you are experiencing a trailer jackknife, you can help your tires regain traction by releasing the brakes. Using a trailer hand brake while experiencing a skid will only cause the skid to continue.
