15 . 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.
16 . The trailer hand valve should:
Be used on slippery surfaces.
The trailer hand valve works the trailer brakes but should only be used when testing them. Using it while driving could create a skid. Never use the trailer hand valve while parking because doing so may release the air pressure from the braking system, releasing the brakes that are holding the vehicle in place.

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.

The trailer will stop.
A trailer tends to swing around, potentially resulting in a trailer jackknife, if its wheels lock up.
