Turn the steering wheel all the way to the left until the trailer straightens out.

10 . The trailer hand valve:
Should only be used when transporting cargo.
The trailer hand valve should not be used for parking. This could cause all of the air to leak out of the braking system, resulting in the brakes releasing. Instead, use the parking brake.
11 . 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.

It is raining.
Rollovers happen when an operator turns too fast. Drivers should be sure to slow down before entering turns and curves, especially when transporting a fully-loaded rig.

Slow, planned stops.
When driving a combination vehicle, it is important to brake well in advance and look far ahead of your vehicle to avoid the need for sudden stops. Making habits of these actions will help you prevent your trailer from jackknifing.
14 . ____ are the cause of more than half of all accident-related truck driver deaths.
